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
