Andrew McKechnie (1477) v lcruz (1600)
The Falkbeer Counter Gambit was once thought to be the refutation of the King's Gambit but it has now vanished from GM play. 4.d3 and 6. Nf3 solve all of White's problems.
White need not fear Qh4+.
( 7...Bf2+ 8.Kd1 )
The book move is Na6
( 8...Na6 9.Bxc5 Naxc5 10.Nbd2 O-O 11.O-O-O Bf5 12.Nd4 Qf6 13.Nxf5 Qxf5 14.Nxe4 Nxe4 15.Qf3 Nd6 16.Bd3 Qd7 17.g4 )^
Nd7 loses the light squared Bishop.
( 13.Nd4 Qf6 14.g4 Bxg415.Qxg4 ). There is nowhere for the Bishop to go.
Nd4 must be played to win the light squared Bishop.
After Nd4 black is in a lost postion.
( 15.Nd4 bxc4 16.Nxf5 Qf6 17.Bd4 Qxf5 18.Bxe4 Qh3 19.Qxc4 Qxh2 20.Re3 f5 21.Bxf5) Black goes two pawns down with two isolated pawns on the Queen side. Black had to remove the Bishop from d4 so it can no longer protect the Rook going to h1.
Black should have taken with the Knight. After Nd4, black loses.
( 16.Nd4 Qg6 17.Nxf5 Qxf5 18.Qxb5 Ndf6 19.Bd4 Rab8 20.Qa4 Qh5 21.Bxe4 Rxe4 22.Rxe4 Nxe4 23.Bxg7 Kxg7 24.Qxe4 Qxh2). And black has four isolated pawns to white's six pawns in two pawn islands.
After NxBf5 black loses.
( 17.Nxf5 gxf5 18.Qxb5 Reb8 19.Qc6 Qxc6 20.dxc6 Ndc5 21.Bxc5 Nxc5 22.Re5 Ne6 23.Rd7 Rd8 24.Rxf5 Rxd7 25.cxd7 Rd8 26.Rd5). Black has four isolated pawns to whites seven in two pawn islands with a pawn on d7. )
Qf6 and black loses. Black can win back the advantage here with Nc3.
( 17...Nc3 18.bxc3 Qa3+ 19.Kb1 Nb6 20.Bc1 Rxe2 21.Bxa3 Bxc2+ 22.Ka1 Bxd1 23.Rxd1 Rae8). And black has won the exchange with two points material advantage.
( 21.Bxe4 Rxb5 22.Bxf5) And white has won a Knight.
( 22.Bxe4 Nxe4 23.Qh6 Qg624.Rg1 Nf6 25.Rxg6+ hxg6 ) Black is forced to exchange the Queen for Rook. If not:
( 23...Nf6 24.Rg1+ Ng4 25.h3 Qg6 26.Rxg4 )
And again black is forced to exchange the Queen for a Rook.
( 23.BxNe4 Qg6 24.Bxg6 hxg6 25.Rxg6 fxg6 26.Qxf6+ )
If not: ( 23...Qh5 24.Bc5# )
Again BxNe4 and black must exchange the Queen for a Rook.
