[Event "London"] [Site "?"] [Round "0"] [White "Steinitz"] [Black "Deacon"] [Result "1-0"] [ECO "C39"] [Opening "KGA: 3.Nf3 g5 4.h4"] 1. e4 e5 2. f4 exf4 {Black accepts the gambit pawn. But what does White gain from this? The f-file is now open for White's rook after castling. White also has an abundance of central pawns.} 3. Nf3 g5 4. h4 {This move introduces the Kieseritzky and Allgaier variations to the King's Gambit.} 4... g4 5. Ne5 Nf6 { 5...Bg7 6.d4 would leave White in control of the center.} 6. Bc4 d5 { The only move to block White's attack on the f7 pawn.} 7. exd5 Bd6 8. d4 Nh5 9. Nc3 Qe7 {This move is a mistake as it breaks the opening rule that one should not develop the queen before castling. 9...O-O getting the king out of the center was a better move.} 10. Bb5+ c6 {This move leads to Black's defeat due to tactics on the a4-e8 diagonal. 10...Bd7 11.Qxg4 when Black's light squared bishop is unable to capture the White queen due to White's control of the a4-e8 diagonal. 10...Kf8 perhaps is the best move although Black's king would not be very safe on the semi-open f-file.} 11. dxc6 bxc6 12. Nd5 {Initiates a beautiful combination made possible by White's light squared bishop pinning Black's c-pawn.} 12... Qe6 13. Nc7+ {A clearance sacrifice which opens the a2-g8 diagonal for White's light squared bishop.} 13... Bxc7 14. Bc4 Qe7 15. Bxf7+ Kf8 16. Bxh5 { White has a won game due to the exposed position of Black's king.} 16... Bxe5 17. dxe5 Qxe5+ 18. Qe2 Qxh5 { 18...Qxe2+ 19.Kxe2 when Black has no way of preventing the loss of his f- pawn. } 19. Bxf4 {White is a piece down but Black's exposed king and backward development give White a winning initiative.} 19... Bf5 { Black tries to block the f-file leading to his king, but it is too late.} 20. O-O Nd7 21. Bh6+ {A decoy move which aims at driving Black's queen from the protection of his bishop.} 21... Kf7 { White now has a combination that wins Black's queen.} 22. Rxf5+ Qxf5 23. Rf1 Qxf1+ 24. Qxf1+ {Although Black has two rooks for the queen his position is lost because of his open King's position.} 24... Kg6 25. Bg5 h6 { 25...Rhf8 would allow White to win material.} 26. Qd3+ { Black resigned since he either loses material or gets mated.} 1-0
