Nf3 g6 3. g3 Bg7 4. Bg2 O-O 5. O-O d6 6. c4 {The Fianchetto Variation is on completely different lines than other K- Indian variations. White's K-side is more solidly defended than in otjer variations.} Nbd7 {Equally popular is 6...Nc6. It goes against the dogma which states that after 7.d5 Na5 black's N would nit be well placed on the edge of the board. However, experience hs shown that the extra pressure on c4 is sufficient compemsation. Therefore, after 6...Nc6 white usually replies with 7.Nc3} 7. Nc3 e5 8. e3 c6 9. b3 e4 10. Nd2 d5 11. Ba3 (11. a4 {is the alternative.} Re8 12. b4 Nf8 13. a5 Bg4 {and black has a good game. Vajda,L (2599)-Cuhendi,S (2406) Dunajska Streda 2017}) 11... Re8 12. Rc1 {White has tried many different moves here such as 12.Qe3, 12.cxd5, 12.f3 and even 12.Bd6. The position is that equal.} a6 {An interesting alternative is 12...Nf8} 13. Qc2 {This does not turn out well. White needs to do something about black's center and so 13.cxd5 and 14.f3 are in order.} Nf8 14. Na4 {The N is misplaced here. Unlike in the note to black's 6th move, here the N has no influence on the position. Stockfish likes the mysterious 14.Nd1, but more human-like seems 14.cxd5 and 15.f3} b5 15. Nc5 h5 16. cxd5 cxd5 17. b4 {White's N has an outpost at c5 and he has the c-file. The only problem is that neither of these factors play a part in the gae,; all the action is going to be on the K-side where black has a makings of a strong attack.} h4 18. Ndb3 {Of course not 18. gxh5 wrecking his K-side.} hxg3 19. fxg3 Ng4 20. Rce1 {It's better to defend the P with this R because the other one offers some resistance on the f-file.} f5 21. Bc1 Nh7 {Very interesting. There is no way to immediatley continue the K-side attack, so Evans maneuvers this N way over to c4, not so much to blockade the c-file as to put pressure on the e-Pawn. White is pretty much helpless and can only wait.} 22. Na5 Ng5 23. Bd2 Nf7 24. Qb3 Nf6 25. Rc1 Nd6 26. a4 Nc4 27. Qa2 Be6 28. Rfe1 Bf7 29. Bf1 Ng4 30. Nxc4 dxc4 31. Qb2 Qg5 32. Ra1 Bf8 {Evans is going to transfer the B to a better diagonal from where it can participate in the attack.} 33. Ra3 Bd6 {The threat is ...Nxh2} 34. Bc1 Bd5 {He could still play ...Nxh2, but before he plays it, Evans prefers to make way for the R to come to the h-file.} 35. Qg2 Kg7 36. Be2 {This loses immediately, He could have held out longer with 36.h4} Nxh2 37. Qxh2 Rh8 38. Qg2 Rh7 {Doubling Rs on the h-file ends the game.} 39. Ra2 {All of white's maneuvering on the Q-side has come to naught.} Rah8 40. Bf1 Bxg3 41. Ree2 Bh2+ 42. Kf2 Qh4+ {White resigned, It's mate next move.} 0-1
