2006 Apr. Toledo Swiss- R4

Hyslop,N (1648) - Prong,C (1904)
2006 April Toledo Swiss, 4.8.2006
Spanish Opening: Bogolyubov Variation [C91]

1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 b5 6.Bb3 Be7 7.Re1 0-0 8.c3 d6 9.d4 Bg4 This is the Spanish Bogolyubov variation
10.d5 Na5 11.Bc2 h6
I was out of book at this point. The book move was c6.
12.b3
The aim of the move is to take away c4 from the a5 knight. At the same time though, this seriously cramps the white light squared bishop, which was already bad due to the d4 pawn.
12...Bh5 13.h3 Qc8 14.Kh2 Nb7 15.b4
While this move does hamper the b7 knight, it also creates a weakness on c3.
15...a5 16.a3 axb4 17.cxb4
Black really had no way to get at the c3 pawn immediately, so instead he turned to opening lines for his rook.
17...c5 18.dxc6 Qxc6
The contrast between white's rooks and queen couldn't be any greater. The black queen is active on both an open file and diagonal. Both of whites rooks are defensively postured, meanwhile the black rooks stand ready to fire down the half open a-file or the open c-file.


19.Bb2 Qb6
I considered Bxf3 because the queen cannot recapture on f3. Therefore, the white king's pawn shield would be shattered.
20.Qe2 Nd8 21.Nbd2 Ne6
The once useless knight on a5 has been redeployed and now stands poised to jump to either d4 or f4.
22.g3 Rfc8 23.Bb3 Ng5
This move forces another pawn move in front of the white king.
24.g4 Nxf3+ 25.Qxf3 Bg6 26.Rac1 Nh7
The knight prepares to move forward to g5.
27.h4?
An oversight on the part of the white player. He missed the bishop perched on e7 controlling the h4 square.
27...Bxh4 28.Qg2?
White could have prevented the immediate loss of the f2 pawn with Rxc8+ or Kg2. 28...Bxf2 29.Rf1 Be3 30.Rcd1 Ng5 31.Bd5 Ra7 32.Nf3?
White gives away another pawn. Nb3 or Nb1 would have been better.
32...Bf4+ White has seen enough carnage and resigns. 0-1

2006 Toledo May Swiss

I took a carload of players down to Toledo for the May Swiss, since I can't afford the $70 entry fee that Ed Mandell charged for his 2 day tournament this weekend. The other players with me either had the same complaint about the cost, or they were unavailable for 2 day of chess. Anyhow, the tournament is rated already.

I scored 2/4 with wins against Michiganians Scott Rogers and Loren Schwiebert, winning with white and then black respectively in the first two rounds. I lost games 3 and 4 to Paul Maginley with white and then John Gattinger with black. Incidentally, I missed tactics in both games that allowed me to get checkmated. I will post those games before too long with annotations.

The other guys with me were: Al Foord 2/4 +0, Loren Schwiebert 2/4 -17, and my brother Paul Prong 2/4 +90. My brother played 4 people rated at least 200 points above him in each game and scored magnificently against tough competition. This brings his rating up to 1324, and more in line with his actual skill level.

Finally, it seems my scoresheet is not accurate enough to reconstruct my April game against Nathaniel Bromberg. This is only the 2nd time in 231 USCF rated games that this has happened to me. If I am able to get a hold of his scoresheet, then I will post the game with annotations at a later date.

Prong,C (1901) - Carter,A (1836)
2006 April Toledo Swiss, 4.8.2006
Caro-Kann Defense: Advance Variation [B12]

1.e4 c6 2.d4 d5 3.e5 Bf5 4.Nf3 e6 5.Be2 Nd7 6.0-0 Ne7 7.c3 c5 8.Be3
Benjamin played 8. dxc5 against Seirawan in the 1991 US Championships. MCO scores that line +-
8...Nc6 9.a3 c4 10.Nbd2 b5 11.b4 a5 12.Re1 a4
I must admit, I really didn't expect Ashley to close off the queenside. However, her plan is now clear. She intends to castle queenside and shelter her king behind that wall of pawns.
13.Nf1 Be7 14.Ng3 Bg6 15.h3 Qc7 16.Qd2 0-0-0 17.Bf4 h6
I was now seeking a plan. Ashley's king was safely locked away on the queenside. I needed to get my rooks into the game, however there were no open files. Therefore, I decided to temprarily move my king to h2, bring the king back to the queenside by hand, and then march my kingside pawns up the board with the rooks behind them. This is a very slow developing plan, but in a closed position like this there is much more time for positional maneuvering than in open games.
18.Kh2 Rdg8 19.Rh1 Bd8 20.Kg1 Ne7
At this point I realize that I have to consider the possibility that the e7 knight is coming to the f5. At that point, I expected that the knights would be traded off. 21.h4 Nf5 22.Kf1 Nxg3+ 23.Bxg3
With the capture by the bishop on g3 I maintained a solid kinside pawn structure, although if my king was more secure, then I probably would have looked to open the f-file.
23...Bh5 24.Ke1 Be7 25.Ng1 Bxe2 26.Kxe2
With the king perched on e2, I finally have room to bring my a1 rook over to the kingside and join in the impending attack. 26...g6 27.Bf4 h5 28.Nf3 Nf8 29.Bg5 Bxg5 30.Nxg5 Qe7?
This loses a pawn. Nh7 would have held.
31.Qf4 Kd7 32.Nxf7 Rh7 33.Nd6 Kc6 34.Rh3 Nd7 35.Qg5
In retrospect, I don't like this idea. After hxg5 there is no place for the white king to penetrate the black position.

Now the white king has no entry point into the black position.
35...Qxg5 36.hxg5 Rhg7 37.Rah1
I think Rg1 was more accurate as it lends support to the pushing and trading of the doubled g2 pawn.
37...Nb6 38.Rf3 Nc8 39.Nxc8 Rxc8 40.Rf6 Kd7 41.Kf3
The king belonged on e3 if I was going to move it as I needed to push both the f-pawn and g-paw. So on f3 it is in the way.
41...Rh8 42.Rh4 Ke7 43.Kf4 Rhg8 44.g4 hxg4 45.Kxg4 Re8 46.Rh2 Reg8 47.Rf3 Kd7 48.Rh6 Ke7 49.Rfh3 Kf7 50.Kg3 Kf8 51.Kh4 Kf7 52.Kg4 Kf8 53.Rf3+ Ke7 54.Rf4 Kd7 55.Kg3 Ke7 56.f3 Kd7 57.Rfh4 Ke7 58.Rh8 Kf7 59.Rf4+ Ke7 60.Rh6 Kd7
I allowed this draw with about 2 minutes left on my clock. However, with time white may still be able to play for a win. The idea would be to play Rf6 and then move the white king off the g-file. Next, white would play f4 and sacrifice the f-pawn on f5. This would open up play for a rook battery for white along the 6th rank.
½-½

2006 Apr. Toledo Swiss- R1

Prong,C (1903) - Amarasinghe,P (1287)
2006 April Toledo Swiss, 4.8.2006
King's Gambit Accepted: Schallop Defense [C34]

1.e4 e5 2.f4 exf4 3.Nf3 Nf6 4.e5 Nd5
This move deviates from the book line, which is Nh5 (a position deemed equal).
5.Bc4 Nb6 6.Bb3
From b3 the white bishop temporarily dominates the b6 knight.
6...Be7 7.0-0 0-0 8.d4 d5 9.Qd3
White should probably have played Bxf4.
9...c5 10.c4?
White drops a pawn with this line. After dxc5 white can maintain equality.
10...dxc4 11.Bxc4 Nxc4 12.Qxc4 Be6
An excellent idea. Black develops with tempo, and takes a nice lead in development to accompany his lead in material.
13.d5 Qxd5 14.Qxf4 Nc6
Black spots a weakness and piles on attackers against the e5 pawn.
15.Nc3 Qc4 16.Qg3
Black is only a pawn ahead, and I can probably get the pawn back later. Still the old mantra is to trade pawns when you are behind, and pieces when you are ahead. So i decline the exchange of queens.
16...Qg4 17.Qf2 Nd4
An intriguing idea was f6 threatening to unleash a rook down the f-file against the queen.
18.Nxd4 Qxd4 19.Be3
Black is succeeding in trading off pieces, and now he adds another pawn to his lead as I choose to decline another offer to exchange queens. White could have held onto the pawn with either Bf4 or Qe3.
19...Qxe5 20.Rfe1 Rfd8
Black can igonre the potential discovered attack on his queen for now. 21.Rac1 b6 22.b3 Qf6 23.Qe2
The battery Qe2 sets up a potential discovered battery attack down the e-file 23...Qg6 24.Qf3 Rab8 25.Nb5 Bd5 26.Qh3 a6
Black has left a piece unprotected. That signals an alert to look for combinations. 27.Bf4
Black has to calculate carefully now. He can hold his lead with Bg5 or Be6.


27...axb5
However, he could not afford to take the knight on b5. White will not only equalize now, but take a small lead.
28.Bxb8 Be6 29.Qg3 Qxg3 30.Bxg3
White is now up an exchange for a pawn.
30...Rd2 31.Bc7 Rxa2 32.Bxb6 Rb2 33.Bxc5 Bg5 34.Be3 Bxe3+ 35.Rxe3 g6 36.Rc5 Rxb3 37.Rxb3 Bxb3 38.Rxb5
White has miscalculated. He still holds a slight lead, but black will be able to build a fortress. The key in this position is that the bishop will be able to protect the black pawns because they are all on the light squares. Furthermore, the rook has no entry points into the black position.
38...Be6 39.Kf2 h5 40.Ke3 Kg7 41.Kf4 Kf6 42.h3 Bc4 43.Rb6+ Be6 44.Ra6 Kg7 45.Ke5 Bc4 46.Ra7 Bf1 47.Ra2 Bc4 48.Rf2 Bb3 49.Kd6 Bc4 50.Ke7 Be6 51.Rf4 Bd5 52.g3 Be6 53.g4 hxg4 54.hxg4 Bd5 55.g5 Be6 56.Rd4 Bb3 57.Rd6 Bc4 58.Rf6 Bd5 59.Kd6 Bc4 60.Ke7 Bd5 61.Rd6 Bc4 62.Rc6 Bd5 63.Rd6 Bc4 64.Rb6 Bd5 65.Kd6 Be6 66.Ke5 Bc4 ½-½

Tactics from Derek Wilder

Derek Wilder (1711) played a sensational tournament at the National K-12 Championships finishing with 5/7. This is a position from his 7th round game against Daniel Rohde (1891). Here Derek is white and black is about to play Rf5 trapping the white queen. How did Derek save this position?

BND match vs. Eli Rogers

Rogers,E - Prong,C (1904) [C57]
Brand New Day Cafe, 04.20.2006
Two Knight's Defense: Ulvestad Variation [C57]

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 b5 6.Nxf7?
Clearly white had better options. Surprisingly, Bf1 is the book response here. 6...Kxf7 7.dxc6+ bxc4
For the knight sacrifice, white has gotten 2 pawns. Furthermore, he has fractured the black queenside pawn structure and destroyed black's hope of castling. However, the pawn on c6 is not long for this game, and the lead that black has in development will not be going away anytime soon.
8.0-0 Qd5 9.Nc3 Qxc6 10.d3 cxd3 11.cxd3
Forced. On Qxd3 comes Ba6 with a skewer of the white queen and rook. I struggled with this move. I knew I wanted to develop a bishop, but finally I decided that Bc5 was stronger because it pinned the f2 pawn.
11...Bc5 12.h3 Bb7 13.Ne4
Taking the e4 knight looked scaryto me because after dxe4 the black king is exposed and the white queen has access to the d-file, in addition to the b3, f3 and h5 squares for potential checks.
13...Rad8
Pinning the d3 pawn, and causing the knight on e4 to become unprotected.
14.Ng5+ Ke7 15.Nf3 Rhe8 16.Bg5 Kf8 17.Be3 Bxe3 18.fxe3 Ba6
Now on Rc1 black plays Qb6, and will threaten the fork of the b2 and e3 pawns, in addition to winning the d3 pawn.
19.Ng5 Kg8
I looked at Bxd3, and it looked very good. However, I decided to get my king tucked away and play it safe, since I was ahead.
20.Rc1 Qb6 21.Re1 Rxd3 22.Qa4 Rxe3 23.Kh1 Rxe1+ 24.Rxe1 Qb5
Since black is up a piece and a pawn it is time to trade off the queens, which should remove most of the drawing chances that white might find.
25.Qa3 Qc6
This move has two purposes. On the surface it seems like it is simply an attempt to control the h1-a8 diagonal and pin the g2 pawn to the king. While that is true, it also has the added benefit of helping to control the square directly in front of the passed pawn. White now hits e4 2 times and gains control of the square so that the e pawn may be pushed one stepped closer to the promised land.
26.Nf3 e4
I wanted to play this move right away, but it is improtant to examine what you give up when you remove a piece from one square to move it to another. In this case I relinquished control of the d4 square. I decided this wasn't critical because I could move my queen to d6 with a gain of tempo, since white probably did not want to trade queens.
27.Nd4 Qd6 28.Qa4 e3 29.Nf5 Qd3
Protecting both the pawn on e3 and the bishop on a6. Furthermore, the queen attacks the knight on f5.
30.Nd4 Re4 31.Rd1


Rxd4
Temporarily giving back some material, but this is inconsequential since black will promote his pawn, and win the game.
32.Qxd4 Qxd4 33.Rxd4 e2


With no hope of stopping the pawn from queening. 0-1

Black to move: Mate in 4

This position comes from a G15 OTB game I played today. Can you find the combination?

BND match vs. Bob Mayer

Brand New Day Cafe, 03.09.2006
Sicilian Defense: Closed Variation [B23]

1.e4 c5 2.Nc3 Nc6 3.Bb5
g3 and f4 seem to be the more common book lines for white. NCO does list Bb5 as an intersting sideline.
3...a6
Nd4 was the accurate response I didn't find.
4.Bxc6 bxc6
I captured towards the center in hopes of opening the center later with d5 and undoubling my c-pawns.
5.Nf3 e6 6.b3 d5 7.e5 Ne7 8.Ba3 Ng6 9.g3 Be7 10.h4
White is hoping to force the knight back to the eighth rank.
10...Qc7 11.Qe2 0-0?
While not losing material straight away, this seemingly logical move allows white to kick the g6 knight to h8, a horrible post for a knight.
12.Na4 Qa5 13.Qe3
h5 is still a better choice. It forces the retreat of the g6 knight to h8, and nearly stables the poor horse there permanently.
13...d4 14.Qe4 Bb7 15.h5 Nh8 16.0-0-0?
Missed tactic here. Nxd4 cxd4 allows white to win a pawn after Bxe7.
16...Rfe8 17.Nxc5
A terrible blunder.
17...Qxa3+ 18.Kb1


Bxc5
A positional error. The black bishop was controlling the critical g5 square. Now black will have to defend a fierce white attack.
19.Ng5 g6 20.hxg6 Nxg6 21.Nxh7
White gains tempo with Rxh7, because he needs to lift the h1 rook anyway to gain space for Rdh1. Sure the knight fork on f6 is good if white can get it in, but there is truly no chance that a good player will not find an adequate defense for that. 21...Kg7 22.Nf6 Rh8 23.Nh5+ Kf8
Black now has the option of fleeing with his king to the queenside if need be.
24.d3 Rd8
Preparing Bb4 followed by Bc3 and Qb2#
25.f4 Bb4 26.c3 dxc3 27.Rc1??
Qe2, Qg2 and Rh2 all allow white to play a few more moves.
27...Qb2# 0-1

2006 April Toledo Swiss

There was a good turn out today. There were 24 players in all, and a total of 5 in class A. Will Rhee shared first place with 3.5/4, and I shared the Class A Prize with John Gattinger and Ashley Carter, as we all score 3/4. I played Ashley to a draw, although I was up a pawn. I'm certain there was a way to win the game before I traded off queens. I will analyze the game sometime this week and post my analysis.

Rapid Tactics

I was playing white in this 5 minute game. It is black to move. He plays b6. How did I take advantage?

Missed Tactic from Mayer-Prong 3/2/06

This is a position from Mayer-Prong at BND Cafe on 3-2-06. White missed an opportunity to win material here. What should white have played?

Carrel Chess Club- 3/23/2006

The meeting was called to order just after 6PM. There were 8 members in attendance, and Mike got a call saying that Loren Schwiebert was on his way. So we played some G/5 skittles while we waited. My brother Paul made his inaugural appearance tonight. After winning 2/3 speed games, the Schwiebert's showed and we got started. I was paired with Joel Schwiebert and my brother was paired with Rodney (don't recall his last name). Anyhow, I received an e-mail this afternoon from Will Rhee informing me that he wouldn't be able to make it this evening. Paul and I both won our games. Not sure who the other winners were, and in fact I'm not 100% certain what the other pairings were. Anyhow, a good time was had by all. I will post my game complete with annotations soon.

Carrel Chess Club

Mike Carrel has been running the Carrel Chess Club on Thursday nights at 6PM at the Brand New Day Cafe in Canton, MI. The cafe is on the northwest corner of Cherry Hill and Lilley, right next door to a Subway.

Anyhow, most of the players are either D or E players, but the club is not terribly far from my house. Furthermore, Mike has been running a one game a week rated G45 "round robin" with whoever show up each week. The best part about the whole thing is that there is no cost for these games. Rated chess for free!

I took last week off and had dinner with my wife. The next day I found out that Mike had recruited Will Rhee, a fellow class A player, to come and give me a bit of a challenge. Unfortunately, I didn't realize Will was making the trek from Ann Arbor. However, I will be attending this week, March 23rd. Hopefully I will have an opportunity to play Will.

BND match vs Sanjay Sharma

Sharma,S (939) - Prong,C (1798)
Brand New Day Cafe, 03.02.2006
Queen's Gambit Declined: Tarrasch Defense [D32]

1.d4 d5 2.c4 e6 3.Nc3 c5 4.cxd5 exd5 5.Nf3 Nc6 6.Bf4
I hadn't studied up on this particular line of the Tarrasch Defense, but I managed to play the next book move anyhow.
6...Nf6 7.e3 Be7 8.Bd3 0-0 9.0-0 Re8 10.Rc1 a6 11.a4
This move created a potentially big hole on b3, if the queen ever deserted its protection of that square.
11...Bg4 12.Be2 dxc5
seems to be a more effective method of protecting the weakness on d4.
12...Rc8 13.Qd2
This removes the protection on the b3 square. dxc5 would have been preferable. 13...Na5
Now the c6 bishop heads for the hole on b3.
14.Ne5?? Nb3
White did not recognize the potential knight fork on b3, so black take immediate advantage.
15.Qd1 Bxe2
Clearly betted than Nxc1 Bxg4
16.Qxe2 cxd4
I was looking for potential ideas that would win more material than just the exchange. This intermezzo requires the response Sanjay played and still allows black to gain the exchange. Additionally, black opens the c-file for his rook.
17.exd4 Nxc1 18.Rxc1 Qb6 19.Rd1 Bd6 20.Qf3 Qb3
Qxb2 is probably a better option.
21.Rb1 Bb4
The b2 pawn is pinned, and thus would not be able to capture on c3 should black play Rxc3 or Bxc3. The bishop give black one extra attacker so that the queen cannot recapture on c3.
22.Bd2 Bxc3 23.Bxc3 Ne4??
This allows Qxf7. Better was Qxa4.
24.Rc1?? f6 25.Ng4 Nxc3 26.bxc3 Rxc3!
A beautiful mating combination!

27.Qxc3 Qxc3 28.Rxc3 Re1# 0-1

BND match vs Joseph Moceri

Moceri,J (865) - Prong,C (1798)
Brand New Day Cafe, 02.16.2006
Sicilian Defense: Counter Attack Variation [B40]

1.e4 c5 2.Nf3 e6 3.Bb5
This move begs black to play a6. Then the bishop has to retreat to e2.
3...a6 4.Ba4?


This move guarantees the loss of the bishop for a pawn or two.
4...b5 5.Bb3 c4 6.Nd4
You can't attack with just one piece. White needs to develop some other pieces. Castling, Nc3 and d3 are all better moves.
6...e5
Probably should have taken the bishop right away to prevent an isolated a-pawn. 7.Nf3 Nc6 8.d4 exd4 9.Nxd4 Bb7
Taking on d4 would have centralized the white queen. Now if white takes on c6, then black will have his bishop targeting the e4 pawn and controlling the long a8-h1 diagonal. The rule of thumb here is that when trading material... the person who captures last generally will gain tempo.
10.0-0 Qf6 11.c3 Nxd4 12.Qxd4 Qxd4 13.cxd4
In this case white doesn't really gain a tempo so much as a full pawn center. 13...cxb3 14.Re1
Chris didn't want to double his queenside pawns.
14...bxa2
However, I noticed that if the white rook was on a2, then it would have to waste a tempo to get back to an active square. This assumes that I was going to prevent him from any activity along the a-file.
15.Rxa2 Bb4 16.Re3 Rc8 17.Rc3?
Chris said he hadn't realized that he could play Nc3 and avoid the loss of the exchange. Clearly he was afraid of a possible back rank mate threat.
17...Bxc3 18.Nxc3 Ne7 19.Bf4 Ng6
Fritz likes the knight on c6 better because it hits the d4 pawn. However, I didn't like the fact that it blocked my bishop.
20.Be3 0-0 21.Ra1 Rfe8 22.f3
After this move I had difficulty recognizing what the correct plan was. I figured I would double the rooks on the c-file and then drive the knight away with b4. 22...Rc4 23.d5 b4
I really dont know why i didnt double the rooks first.
24.Na4 Bxd5
This is good, if not for the weakness of the b6 square.
25.Nb6 Be6 26.Rxa6
White needed to win back the exchange here with Nxc4.
26...Rc2 27.Na4 Ne5
I missed the idea of Nh4 forking the pawns on g2 and f3. Black will win one of them with this idea.
28.Ra7 Nd3 29.h3 Rec8 30.Nb6 Nxb2
This idea is clearly inferior to simply moving the rook. However, I saw the passed pawn on the b-file would queen on a dark square, and the bishop would be of no help in preventing the pawn from queening.
31.Nxc8 Rxc8 32.Rb7 b3 33.Kh2
I thought it was probably time for a king move, but the king has to move toward the passed pawn to help prevent promotion.
33...Nd1 34.Bd4 h6
Not a necessary prophylactic move, but it does prevent back rank mates. Furthermore, black has time.
35.f4 g6
I played this move to prevent the loss of the d-pawn and to allow the bishop to remain posted on e6.
36.Kg3 f5 37.exf5 gxf5 38.Kh4 Kh7 39.Kh5 Nc3 40.g4 Ne2 41.Bf6 fxg4 42.hxg4
Allowing a forced mate.
42...Rc1 43.g5 Rh1# 0-1

Lack of Posts

Sadly it has been nearly a month since my last post here. I have had plenty of time to post, but I haven't been playing in tournaments. Therefore, I have lacked subject matter. This all corresponds with my lack of employment, which in turn has led to a lack of funds. Furthermore, the only work I have found has been teaching an ACT Prep class for Sylvan Learning Center in Novi. Unfortunately, the classes are on Saturdays, but will end at the closing of March. Hopefully, I will be employed again soon and be able to resume my chess activities.

2006 Feb. Toledo Swiss- R4

Prong,C (1798) - Clinton ,J (1133)
2006 February Toledo Swiss, 2.11.2006
King's Gambit Accepted: Schallop Defense [C34]

1.e4 e5 2.f4 exf4 3.Nf3 Nf6 4.e5 Ne4
The book line has the knight going to h5.
5.d3 Ng5 6.Bxf4 Nxf3+ 7.Qxf3
This has to be better for white. Black has played 6 moves and only has spaces on e7 and g8 to show for it. Meanwhile, white has developed two pieces and gotten two pawn moves in.
7...Nc6 8.c3
Preventing further advance of the c6 knight.
8...Bc5
This move simply encourages white to strengthen his pawn structure by allowing white do so with tempo.
9.d4 Bb6 10.Bc4 0-0 11.Qg3 Qe8??
Black is now going to be forced to give up the exchange because he didn't anticipate the mate threat after Bh6.
12.Bh6 g6 13.Bxf8 Qxf8 14.Rf1
I didn't want to castle here because it would have created a pin of the d4 pawn. I figured I would still have time to castle queenside if I needed to.
14...d6?
This gives away another pawn.
15.Rxf7 Qh6 16.Nd2
Protecting the bishop on c4, preventing Qc1+ and preparing to castle queenside if necessary.
16...Na5

17.Qf4
Trading queens is definitely playable, but whtie had better, namely 17. Rd7+ Nxc4 18. Rd8+ Kf7 19. Nxc4
17...Qxf4 18.Rxf4+ Nxc4 19.Nxc4 dxe5 20.dxe5
I chose to play for the passed pawn because of the open files that were going to allow my king o support the advance of the pawn.
20...Bc5 21.Rd1 Be6 22.b3
The idea was that after Bxc4 white would play Rxc4. However, white has allowed black counterplay if black plays
22. ... Re8. 22...b5 23.Na5 b4
This just gives the pawn away. After cxb4, the pawn is defended by the rook on f4. So the bishop is displaced from c5.
24.c4
I didn't look at the position long enough to realize I could take the pawn. I think I impulsively didn't like the look of cxb4 because of the bishop fork of the a5 knight and the king on e1.
24...Bb6 25.Nc6 Be3 26.Rf3
This move is playable even though it allows the skewer of the rooks by Bg4. White can trade answer Rxe3 and on Bxd1, white plays Kxd1 having gained two bishops for the rook.
26...Bg5 27.h3
To prevent the aforementioned skewer.
27...Bh4+ 28.Ke2 Bc8?
Playing a5 would have saved the b4 pawn.
29.Nxb4 Bb7 30.Nd5 Re8 31.Re3 Bg5 32.Re4 c6 33.Nc3 c5
This is a positional mistake that allows the knight right back into the game.
34.Nd5 Bxd5
This exchange is bad because it gives white a connected pair of passed pawns, surrenders the bishop pair, and neutralizes the pressure along the a8-h1 diagonal. 35.cxd5 Bf6 36.d6 Bd8 37.e6 Bb6 38.e7 Kf7
A wasted tempo, but black has nothing anyway.
39.Rf1+ Kg8 40.d7 1-0

2006 Feb. Toledo Swiss- R3

Mowery,E (1146) - Prong,C (1798)
2006 February Toledo Swiss, 2.11.2006
English Opening [A13]

1.c4 e6 2.Nc3 d5 3.e3 c5 4.d4 Nc6 5.g3 Nf6 6.Bg2
White must exhage the c-pawn before moving the bishop to g2.
6...Be7
Even in the opening one must pay attention because changing the move order will sometimes hang pieces.
7.Nf3
Again the c pawn hangs.
7...0-0 8.0-0 dxc4
Finally, I go up a pawn.
9.dxc5 Bxc5 10.Qe2 Qd3
I wasn't terribly excited about trading the queens off to gain a pawn on d3. I didn't think I would be able to hold it, yet I was ahead a pawn and it would not be catastrophic if I gave the pawn back.
11.Nd2
This was a blessing. I felt fairly confident that I could hold the c4 pawn.
11...Qxe2 12.Nxe2 Na5
The only problem with trying to hold the c4 pawn is that it will take awhile for black to get his rooks and light squared bishop active.
13.b3 cxb3 14.axb3 Bb4
This threatens to win the b3 pawn after the exchange on d2. Furthermore, Nxb3 will fork the d2 and a1 squares.
15.Nd4
Black could ill afford to lose the b3 pawn and yield a connected passed pair of queenside pawns to black.
15...e5 16.Ra4 Bc3 17.Nb5
This knight forks the c3 bishop, the a7 pawn and the c7 square, which would be uncomfortable for black.
17...Bxd2 18.Bxd2 Nxb3 19.Bb4
White had to be thinking that black would play Rd8, but the white rooks are susceptible to a bishop fork.


19...Bd7 20.Bxf8 Bxb5 21.Rb4 Bxf1
With the two pawn advantage, black just continues to reade off material.
22.Bxf1 Nd2
I should have jumped at the opportunity to rid my opponent of the bishop pair by playing Rxf8 or Kxf8
23.Be7 Nxf1 24.Kxf1 b6
Nd5 with the fork of the bishop and rook was tempting, but I was going to give up the b-pawn to force an exhange. I figured the two pawn advantage was enough to win. 25.Bxf6 gxf6 26.Ke2 Rd8
This move keeps the king away from my baby queens on a7 and b6.
27.e4 Rd6 28.h4 a6 29.Ke3 b5
One step close to the promised land. With things secure on the queenside, I decided to lock things down on the kingside before proceeding with the coronation.
30.f4 Kg7 31.h5 Kh6 32.g4 Rb6
Preparing a5.
33.f5?
A terrible mistake. This alongs the black king access to the g5 square and forces the white king further from the queenside queening squares.
33...Kg5 34.Kf3 a5
Only a matter of time now that the pawns are rolling.
35.Rb1 b4
The passed pawn must be stopped.
36.Rd1 b3 37.Kg3 b2 38.Rd8 Rb3+ 39.Kg2 Kxg4
Not accurate, but good enough in this position. b1/Q was best.
40.Rg8+ Kxh5 0-1

Prong,C (1798) - Rhee,W (1884)
2006 February Toledo Swiss, 2.11.2006
Sicilian Defense: Sveshnikov Variation [B33]

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Nd5 Nxd5
Forced.
8.exd5 Nb8
GM Neil McDonald gives this move an exclamation mark.
9.c4 Be7 10.Be3
The book indicates that Be2 is the usual move at this point. Furthermore, this bishop will be driven away soon with f5-f4.
10...0-0 11.Be2 a6 12.Nc3 f5
White will sometimes meet this with f2 and Be3, with the idea of parking the bishop on f2 if he gets the chance.
13.0-0 f4 14.Bd2
I am sure Bc1 was better because I wind up spending two tempi trying to maneuver my light squared bishop onto the b1-g7 diagonal. Bd3 would have been the immediate response if the bishop had withdrawn to c1. This begs the question, why did the dark squared bishop get developed to e3 to begin with. If white is going to play this, then he needs to plan to play f3 and shelted the bishop on f2.
14...Bf5 15.Bf3 Nd7
Note that Bd3 would have been met with Be2.
16.Be4 Qe8
Surely this move was played to develop the queen to g6.
17.Re1 g6
This is curious, and seems to conflict with the move Qe8 played just one move earlier. The queen is now blocked in and has no impact on the game whatosever.
18.Rc1 Nc5
With an eye on a potential rook fork on d3.
19.Bxf5 gxf5 20.Qe2 Qg6
After Qg6 my eye was immediately drawn to the unprotected bishop on e7. Bxf4 doesn't quite work because of exf4 Qxe7 and Nd3 forking the white rooks.
21.b4
My goal was to drive the knight away from c5, so that I could play the combination to win the bishop on e7.
21...f3
This tactic enables black to play e4 with tempo and simultaneously give the knight an advanced support point, namely the critical d3 square.
22.Qxf3
White is forced to capture the pawn.
22...e4 23.Qh3
This was necessary to keep the g-file accessible for the rook on e1. Otherwise, white will not be able to prevent black from winning the exchange.
23...Nd3


24.Re3 Bg5
This skewer really changes nothing. The rook can still take control of the g-file and this will open up a discovered attack on the g5 bishop.
25.Rg3 f4??
I was certain Will was going to play h6, but f4 seals his fate.
26.Rxg5! Qxg5 27.Nxe4 Qg6 28.Qxd3
The point behind the temporatry sacrifice exchange.
28...f3 29.g3 Rae8 30.Re1 Qf5
This allows Bh6, but I didn't realize that the black response Qh3 produces a forced mate after Nxf6 Rxf6 Rxe8+ to follow and then mate in 3.
31.Re3 Qg6 32.h4
I played this to prevent simple back rank mates.
32...Re5 33.Ng5
Bc3 was stronger.
33...Ref5
Black doesn't want to trade off pieces.
34.Bc3
This stalemates the black king.
34...Qh5 35.Qd4
Threatening mate.
35...R8f6 36.Qe4
Discovered attack on the f6 rook.
36...Rf7 37.Qe8+
Avoiding cashing in too early with Nxf7 allows white to win the queen.
37...Rf8 38.Qxh5 1-0
