King's Gambit Accepted: Modern Defense [C36]

1.e4 e5 2.f4 exf4 3.Nf3 d5
This move defines the Abbazia or Modern Defense to the King's Gambit Accepted. 4.exd5= Qxd5
This move is not recommended because it allows white to develop the knight to c3 with tempo.
5.Nc3 Qe6+
Now black forces white to develop another piece.
6.Be2 Bd6 7.0-0 Nc6
This is the first move I couldn't find documented in a book. Ne7 is the book continuation. This helps black move toward castling short, and it removes the threat of a pin of the queen along the e-file.
8.Bb5
White should have played Re1. There is more venom in that line. Also worth a look is d4. White doesn't need to move a piece he has already developed. He can finish his development first with d4 and then the c1 bishop is immediately active with an attack on the f4 pawn.
8...Qg6 9.Ne4
Once again white ignores standard opening theories moving a piece that is already developed. More accurate were d4 or Qe2+. Note that d4 threatens d5 and an attacked on the pinned knight on c6.
9...Nge7 10.d3
I really wasn't happy with this move. I wanted the d-pawn on d4. However, for soem reason I didn't want to part with the knight on e4. The only reason to play Ne4 in the first place would have to be to exchange it for the bishop on d6 and remove the key defender of the f4 pawn.
10...Bd7 11.c4?!
This move is horrible. The point was to try and trap the bishop on d6. However, it saddles me with a backward pawn and a bad bishop. Moreover, the trap of the d6 bishop is far from certain and the idea never comes to fruition. White has gone from leading in development to equality, and with more weaknesses than black... this position is clearly better for black.
11...0-0 12.Re1
White could have restored equality with 12. e5 Be5 13. Nxe5 Nxe5 14. Bxe7 Nxe7 15. Bxf4 getting the gambit pawn back
12...Bg4 13.Kh1
I was trying to deal with the knight coming to d4. However, simply playing d4 takes away both d4 and e5, which are the squares that the knight needs to attack f3. Kh1 does remove the pin along the g-file though.
13...Nd4-+ 14.Ba4?
I was looking to redeploy the bishop pn c2, but the knight on d4 will prevent any possibility of activity from the bishop there.
14...Nef5
Black could have further intensified the pressure on the f3 knight with Qh5.
15.Nxd6


Really no tactical advantage for white to play this move now. In fact, it allows a pretty little combination for black if he can force himself to ignore the knight on d6 for a few moves. 15. ...Ng3+ 16. Kg1 Nxf3+ 17. gxf3 and black has a tremendous attack.
15...Qxd6
This allows white to get some counterplay going.
16.Re4 Bxf3 17.gxf3
Opening the g-file was the idea behind Kh1. My log term plan is to place a bishop on b2 and either a queen or rook on g1 and force my opponent to defend g7.
17...Ne6 18.a3
Prepaing b4 to allow the bishop to come to b2.
18...Rad8-+ 19.Bc2 Ne7 Nfd4
threatens to remove the bishop on c2 allowing the pawn on d3 to be captured.
20.b4 Ng6 21.Bb2 c5 22.Qg1
So white has accomplished his plan of setting up the bishop on b2 and queen on g1 with a potential checkmate threat on g7.
22...Qe7
Note that cxb4 is met by axb4, and if Qxb4 then Ba3 skewers the queen and rook along the a3-f8 diagonal.
23.Bc3 b6 24.Rd1 Qg5 25.Qf2
White really doesn't want to exchange pieces while he is down a pawn.
25...Qh5 26.bxc5 Nxc5
Of the three ways that black can recapture on c5, this was the weakest. Qxc5 offers the exchange of queens, which white would presumably decline. However, if he tries to avoid the exchange, then the a3 pawn falls. Finally, the reason bxc5 is better is becasue black doesn't waste a tempo having to return the knight to the kingside. Furthermore, bxc5 doesn't give white the passed d-pawn like the text does.
27.Ree1 Ne6 28.d4
Passed pawns must be pushed!
28...Nh4 29.Be4 Rfe8
Black needs to bring another attacker against the f3 pawn, so Ng5 is the correct move. I thought that this was a blunder at the time, and it is a mistake that loses 2 tempi and 1 point of material. Black should still be able to hold a draw.
30.Bc6= Rf8 31.Bb4 Rc8
Black should have looked at the line 31. ...Rxd4 32. Rxd4 Nxd4 33. Qxd4 Nxf3 34. Qxf4 Nxe1.
32.Bxf8 Rxc6?
Nxf6 would have avoided the pawn fork on d5.
33.d5+- Rxc4
Rc8 would have protected the weak back rank.
34.dxe6 Kxf8??
Black has to accept the fact he is going to be down a awhole rook, and capture on e6. 35.e7+ Facing mate in 1 black resigns. 1-0
