1. e4 e5 2. Nf3 Nc6 3. Bc4 Nf6 { The Two Knights' Defense, a popular reply to the Giuoco Piano. } 4. d3 { A bit passive. White will usually fight for the center by playing c2-c3 and d2-d4. } 4... Bc5 5. Nc3 d6 6. O-O Bb6 7. Na4 Bg4 { Played to prevent White from playing Ng5, doubling up on the f7-pawn. } 8. Bb5 O-O { Now the c6-Knight is no longer pinned. } 9. Bxc6 bxc6 { The doubled pawns are weak but White has no way to immediately exploit the weakness. } 10. h3 Bh5 11. Nxb6 axb6 { Janowski plays this (instead of the undoubling ...cxb6) so that his Rook can control the half-open a-file. He now has a huge space advantage. } 12. Qe2 h6 { Janowski is looking ahead. He wants to develop his Queen but doesn't like the possibility of White playing Bg5 followed by Bxf6, forcing ...gxf6 which destroys the pawn cover in front of his King. The h-pawn's advance prevents Bg5. } 13. g4 { Maroczy attempts to relieve the pin on his f3-Knight, but this only invites a sacrifice by the tactics-minded Frenchman... } 13... Nxg4 14. hxg4 Bxg4 { The Knight is still pinned and the area around the White King is pretty drafty now. } 15. Qe3 f5 { Played to force open lines toward the White King. } 16. exf5 Rxf5 17. Nh2 Bh5 18. Qg3 Qf6 { Notice that if White's Bishop had not been on the c1-h6 diagonal, Black might have played ...Rg5 to win the White Queen. The reason for 18...Qf6 is to prevent White's Bxh6 (...gxh6 would be impossible since the g7-pawn is pinned by White's Queen). } 19. f3 Rf8 20. Be3 Kh7 { Unpinning the g7-pawn. } 21. Rf2 Qe6 { Made possible by the removal of the pin. Now the Queen is out of the f8-Rook's way. } 22. b3 R8f6 { Aiming to play ...Rg6, winning the White Queen. } 23. Kh1 { Maroczy saves his Queen. } 23... Be8 24. Rg1 { Maroczy finally grabs the initiative by threatening mate on g7. } 24... g5 { This grabs some space and shuts down White's play on the g-file. This makes more sense than forcing a Rook exchange by playing a Black Rook to the g-file. Trading Rooks would only weaken Janowski's attacking chances. } 25. d4 { Maroczy wants to trade pawns to open up lines for his Rooks. } 25... c5 26. dxe5 dxe5 27. Re1 { Why not Rd1? Because the Rook would have no good penetration square into Black's position. The squares d5, d6, and d7 are all defended and Rd8 threatens nothing. } 27... Bc6 28. Kg1 { No terrors for Maroczy here -- Black closed the g-file with 24...g5, so there's no way for a Black Rook to pin and win the White Queen. } 28... h5 { This move is a mystery. Janowski has weakened his Kingside (the h-pawn and g-pawn no longer work together). } 29. c4 Bb7 30. Qh3 Kg6 31. Rg2 Qe7 32. Rd1 { THe plan is now Rgd2 and Rd7 with a successful penetration of the Black position. } 32... Rd6 33. Rgd2 Qf6 34. Rxd6 cxd6 { Now the Black pawns are finally undoubled and are all on dark squares (so they don't interfere with the b7-Bishop). } 35. Qg2 Kh7 36. Qh3 Kg6 37. Qg2 Kg7 38. Rf1 Kg6 39. Qc2 Kg7 40. Qe2 { Maroczy really has no idea how to proceed. Black's defenses are pretty strong, but there's always the chance of an error. } 40... Qe6 41. Bd2 Kg6 42. Bc3 Rf4 43. Qd2 Rf6 44. Rd1 Bxf3 { It's hard to figure out what Janowski was thinking here. Most intermediate players wouldn't touch this move. Perhaps fatigue got the better of him. } 45. Nxf3 Rxf3 46. Qxd6 Kf5 47. Bxe5 h4 48. Qxe6+ Kxe6 49. Bc7 g4 50. Bxb6 g3 51. Bxc5 { Not only winning a pawn but also covering the g-pawn's promotion square. } 51... Rc3 52. Bb4 Rc2 53. Rd2 Rc1+ 54. Kg2 Kf5 55. Be7 { Both Black pawns will now fall and Janowski has no chance of preventing a White pawn from promoting. The Frenchman throws in the towel. } 1-0
