Nf3 g6 3. Bg5 {With the huge increase in the popularity of the K-Indian in the 1960s, the Torre Attack was tried as a way of meeting it. White develops his pieces and temporarily avoids placing his Ps in the center in an attempt to limit the influence of the B on g7 by using the P-wedge c3-d4-e3. This allows black a wide choice of setups and he can choose between K-Indian and Gruenfeld-type formations.} Bg7 4. Nbd2 O-O {Black is preserving his options. Now, white usually plays for the P-wedge as mentioned in the note to his 3rd move. His other options are 4...c5, 4...d6 and ...d5.} 5. e4 {This is a decent alternative, but it also gives black slightly better chances than he would get after the P-wedge setup.} d6 6. c3 c5 {Another reasonable plan is to play in the traditional K-Indian style with 6...Nbd7 intending ...e5.} 7. dxc5 {This is the most popular, but white has several other options of about equal value. He can also play 7.d5, 7.Bd3 or 7.Be2} dxc5 8. Bc4 Nc6 9. O-O Qc7 10. Re1 {In this setup white will always protect the e-Pawn either with this or by placing his Q on e} e5 (10... Na5 11. Bf1 Be6 12. Qc2 b6 13. h3 Rad8 {equals. Dreev,A (2683)-Ye Jiangchuan (2676) Dubai 2002}) ( 10... a6 11. h3 b5 12. Bf1 c4 13. a4 Rb8 {equals. Prie,E (2435)-Nevednichy,V (2593) Montpellier 2003}) 11. Nf1 {Intending to reposition the N to d5.} (11. a4 h6 12. Bxf6 Bxf6 13. Nf1 Bg7 14. Ne3 {White's position is the more promising. Prie,E (2435)-Nevednichy,V (2593) Montpellier 2003}) 11... h6 { Forcing white to make a decision about what to do with his B is frequently seen here or, if he chooses, black can also play it earlier.} 12. Bxf6 { Very good. White will gain time as black will be forced to waste a move going back to g7.} Bxf6 {White is better.} 13. Ne3 Bg7 14. Qe2 Rd8 15. h4 {[%mdl 32] White launches an immediate K-side attack.} Na5 16. Bd5 {So, white can’t get his N to d5, but the B will do. Black can’t easily drive it away and his N is not doing anything on a5.} Rb8 {Black’s position is already difficult. He decides to develop his B on b7 to challenge white’s B on d5, but the B never reaches b7.} 17. h5 {White’s advantage is already approaching decisive! hxg6 is the strong threat.} g5 {This is way too risky. Black does best to stand pat with his K-side P-formation and just play 17...Kg7 and wait for developments.} 18. Nh2 {[%mdl 32]} Kh7 {Unable to come up with a reasonable plan to gain counterplay black decides to shore up his K-side.} 19. Nhg4 f6 {Black has apparently succeeded in shoring up his K-side, but as will be seen, he has left himself with fatal weaknesses on the light squares, especially f5 and g6.} 20. Qf3 Rf8 21. Nf5 {White’s pieces occupy beautiful positions.} Nc6 { With nothing to do on a5 the N returns to, hopefully, a better location.} 22. Rad1 Ne7 {Challenging the N on f5.} 23. Nxe7 Qxe7 24. Ne3 {Heading for f5} Rd8 25. Rd2 {White will double Rs on the open file.} b6 26. Red1 Kh8 {Before black can undertake anything he has to ply his K here to avoid deadly checks on f5 or g6.} 27. g3 Qf8 28. Kg2 b5 {Black’s bid for counterplay is too little, too late.} 29. Nf5 Bxf5 {Aaron eliminates the annoying N, but it's no help.} 30. Qxf5 Rb6 {This allows a brilliant refutation, but even with a better defense in the end white’s positional advantages will prevail.} (30... a5 { Black has to keep all three heavy pieces on the 8th rank, but even after something like this he is going to lose anyway. For example..} 31. Bc6 b4 32. Rd7 Rbc8 33. R1d6 Rxd7 34. Qxd7 {and positionally black is hopeless.}) 31. Bg8 {[%mdl 512] Black resigned. His Q is lost.} (31. Bg8 Kxg8 (31... Qxg8 32. Rxd8) (31... Rxd2 32. Qh7#) 32. Rxd8) 1-0
