[Event "Budapest"] [Site "?"] [Round "0"] [White "Alekhine"] [Black "Bogoljubow"] [Result "1-0"] [ECO "A46"] [Opening "Indian: 2.Nf3 e6"] 1. d4 Nf6 2. Nf3 e6 3. c4 Bb4+ 4. Bd2 Bxd2+ 5. Qxd2 d5 {This position resembles a Queen's Gambit, but with the important difference that the dark-square bishops have left the board. Of the remaining clerics, Black's has difficulty having an impact on the game while a pawn sits at e6.} 6. e3 O-O 7. Nc3 Nbd7 8. Bd3 c6 9. O-O {A mistake which allows Black to free his game. 9. Rd1 would have left Black with a cramped game.} 9... dxc4 10. Bxc4 e5 { This move takes advantage of the exposed position of White's queen.} 11. Bb3 { 11.dxe5 Nxe5 12.Qxd8 Nxf3+ 13.gxf3 Rxd8 when Black stands a little better because of White's double f-pawns.} 11... Qe7 {11...e4 12.Ng5 Qe7 13.Bc2 after which White wins the Black e-pawn. 11...exd4 12.Qxd4 Qb6 with equal chances.} 12. e4 exd4 13. Nxd4 Nc5 {13...Nxe4 14.Qe3 when White would win the knight on e4 due to Black's pinned queen.} 14. Bc2 Rd8 {14...Nfxe4 15. Bxe4 Nxe4 16.Qe3 Re8 17.Rfe1 Wins the knight due to the pin on Black's queen.} 15. Rad1 Bg4 16. f3 Ne6 17. Qf2 Nxd4 18. Rxd4 Be6 19. Rfd1 { White's control of the open d-file gives him the advantage.} 19... b6 20. h3 { White prepares to advance his f-pawn but first takes control of the g4 square.} 20... c5 21. R4d2 { 21.Rxd8+ Rxd8 22.Rxd8+ Qxd8 would give Black control of the d-file.} 21... Rxd2 22. Qxd2 c4 23. f4 g6 24. Qd4 Rc8 25. g4 {White's control of the open d-file combined with his kingside initiative give him a big advantage.} 25... Bxg4 { Rather than waiting and getting pushed off the board with pawn e5 or pawn f5 Black decides on a desperate sacrifice.} 26. hxg4 Nxg4 27. Kg2 h5 { 27...Qh4 28.Rh1 demonstrates the point of White's 27.Kg2.} 28. Nd5 Qh4 29. Rh1 Qd8 30. Bd1 {Black resigned because of his material deficit.} 1-0
