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
