1. Nf3 d5 2. g3 c5 3. Bg2 Nc6 4. O-O e5 { This opening goes by a lot of names: King's Indian Reversed, King's Indian Attack, etc. It's a hypermodern opening, in which White allows Black to occupy the center. White will then attack it from the flanks. } 5. c4 { And here comes that flank attack now! Capa plays the Reti opening (named for fellow competitor Richard Reti). The idea is to trade a less-valuable flank pawn for a more valuable center pawn. } 5... d4 { Janowski doesn't go for it. He blocks the center by advancing the pawn. The game will become what's known as a "positional game", a war of maneuver rather than of lightning attacks. } 6. d3 Bd6 7. e3 Nge7 8. exd4 cxd4 { Look at what's happened: Janowski is the one who's traded a flank pawn for a center pawn! } 9. a3 a5 { Janowski makes White's planned b2-b4 impossible. } 10. Nbd2 ( 10. b4 axb4 11. axb4 Rxa1 ) 10... Ng6 { By overprotecting the e5-pawn, Janowski makes it possible for any of the three defenders to move away when needed elsewhere. } 11. Re1 O-O 12. Qc2 Re8 13. b3 h6 14. Rb1 Be6 15. h4 Rc8 { Putting the Rook on the same file as the White Queen in anticipation of the file opening. } 16. c5 { This move serves two purposes: it lashes out at the d6-Bishop and clears c4 for occupation by the Knight. } 16... Bb8 17. Nc4 { This Knight is now quite well placed. It aids in the attack on the e5-pawn and eyes an outpost on b6. } 17... f6 { Necessary, as the pawn would have been lost had Janowski not defended it again. } 18. Bd2 Kh8 { It's possible that Janowski plans (for better or worse) ...Bxc4 and doesn't want to worry about the reply Qxc4 being a checking move. It's hard to say. } 19. b4 axb4 20. axb4 Na7 { The next stop for the Knight is b5. } 21. Qc1 { Capa might be contemplating a sacrifice on h6 (Bxh6) which will win two pawns but give up the valuable Bishop pair. } 21... Nb5 { The Knight's intended jump to c3 puts White's Bishop sacrifice on hold. } 22. Nh2 { Simplicity itself -- Capa uncovers an attack on the b7-pawn. } 22... Qe7 23. Ra1 { Controlling the open file and taking the sting out of ...Nc3. } 23... Rc7 24. Ra5 { Notice how Capa maintains the initiative by making repeated threats. } 24... Bd7 25. Nb6 { Although Nxd7 will be followed by ...Qxd7 (resulting in a minor-piece trade), Capa would then end up with the Bishop pair... } 25... Bc6 { ...so Janowski prevents the possibility while still defending the b5-Knight. } 26. Qc4 { Another move, another threat. Capablanca threatens to trade a Rook for two minor pieces by swapping on b5. } 26... Na7 { Janowski is finally forced to abandon the square. Go back and take a look at position after White's 18th move and compare it to the position now. Look how much space White has gained on the Queenside in the course of eight moves.
 
The interesting thing about this position is the sheer number of possibilities that Capa has created for himself. In addition to the forthcoming Knight fork, he might have played Qa2 (to again threaten to win two minor pieces for a Rook) or even Bh3 (to slice across the center and control even more squares on the Queenside). } 27. Nd5 { Yet another threat (a Knight fork)... } 27... Bxd5 { ...and Janowski responds in the only way he can. } 28. Qxd5 { Capa has won the advantage of the Bishop pair at last. } 28... f5 ( 28... Nc6 { Black might also have lashed out at the Rook to take the initiative and grab back some space. } ) 29. Qf3 Qf6 30. h5 { Capa keeps grinding away at Black, increasing his space and hanging on to the initiative. } 30... Ne7 31. g4 f4 32. Qe4 Nec6 { A double-edged move, defending the e-pawn and attacking the a5-Rook. } 33. Raa1 Rce7 34. Qg6 Qf8 35. Nf3 Re6 36. Nh4 Rf6 ( 36... Rxg6 37. Nxg6+ Kh7 38. Nxf8+ Rxf8 39. Be4+ { White, ahead the Exchange, keeps the initiative. } ) 37. Be4 { Threatening 38.Qh7#. } 37... Qg8 38. Bd5 Ne7 ( 38... Qxd5 39. Qxe8+ { White goes up the Exchange. } ) 39. Qxf6 ( 39. Bxg8 Rxg6 40. Nxg6+ Kxg8 41. Nxe7+ Rxe7 { Again, White is ahead by the Exchange. } ) 39... gxf6 40. Bxg8 Rxg8 { Guess what? White is ahead by the Exchange. } 41. f3 f5 42. Bxf4 { This only looks like a sacrifice, but it's a false one. } 42... Nec6 ( 42... exf4 { Recapturing would only shatter Black's position. } 43. Rxe7 ) 43. Ng6+ Kh7 44. Bxe5 Nxe5 45. Rxe5 Bxe5 46. Rxa7 { Janowski sees he has a piece and a pawn en prise, looks at his present material deficit (two pawns), and packs it in. } 1-0
