Nf3 b6 {Definitly not a good choice of opening. Black has many better lines in Sicilian even simillar to this postion. Generaly speaking it is too early to push pawn on b6, many times it is normal to play b5. Also Black neglects develop and the fight for center. All in all, even if you don't like theory there areplanty of better ideas in the Sicilian.} 3. d4 cxd4 4. Nxd4 Bb7 5. Nc3 ({Someone who prefers a Maroczy setup with the pawn on c4 can play....} 5. Bd3) 5... a6 {Black goes into trouble already as you can see in two examples from top level.} (5... Nc6 6. Bf4 g6 7. Ndb5 Rc8 8. Nd5 d6 9. Qd2 Bg7 10. O-O-O a6 11. Nxe7 axb5 12. Nxc8 Qxc8 13.

Bg5 { Here is also possible to play 6.Be3 with the English attack setup but 6.Bg5 is alse a very good one.} g6 {Not the best choice according to 'theory'. One who is fond of this line is GM C. Bauer, he prefers 6...Qc7} (6... Qc7 7. Bd3 (7. Qf3 e6 8. O-O-O Bc5 9. Bf4 Qd8 10. Qg3 Nf6 11. Bc7 Qc8 12. Be5 Nxe4 13. Qxg7 Rf8 14. Nxe4 Bxe4 15. Bd3 Bg6 16. f4 d6 17. Nxe6 Qxe6 18. Bxd6 Bxd6 19.

Qg4 {[%csl Rg7] 1-0 (28) David,A (2605)-Bauer,C (2592) Paris 2009}) 7. Bc4 { There is one more aggressive example from Slovakia} (7. Qd2 $5 Bg7 8. O-O-O d6 9. Bc4 Nd7 10. f4 b5 11. Bd5 Qb6 12. Rhe1 Rc8 13. e5 {and White was clear better 1-0 (18) Manik,M (2370)-Mrva,M (2435) Slovakia 2012}) 7... Bg7 8. O-O { Even with this silent set up White has better chance from the opening.} d6 9. Bd5 $1 {This is very unpleasent for Black. If Black takes on d5 then the knight comes in with big attacking potential.} Qc8 10. Qd2 Nd7 11. Rfe1 Ngf6 { Black somehow finished development and is ready to castle but still white has the more pleasant postion.} 12. Bh6 O-O 13. Bxg7 Kxg7 14. Qg5 {White is now in attack mode and he threatens 15.Nf5-Nxe7} e6 {Calling for sacrifices} (14... Re8 15. Nf5+ Kh8 16. Nh6 {is also not so good for Black}) 15. Bxe6 {Of course white must take it. He will collect two pawns and a rook for bishop and knight. This is aproximately equal but also it depends more on the postion. In general B+K are better in midlegame but the rook usually dominates in the endgame phase. Here it looks like White can transform the position into an endgame which will be more favorable for him.} fxe6 16. Nxe6+ Kg8 17. Nxf8 Qxf8 18. Rad1 Re8 19. f3 {Here we are. Black hasn't any attacking possibilties and white can simply play it to the endgame.} Re6 20. Qd2 (20. a4 Ne5 21. b3 {was also possible to take a space on queenside. Black can only wait.}) 20... Qc8 21. Qd4 {Centralization is always good.} Qc5 $6 {This is not a mistake of course, but from a general point this pushes the game in to the endgame which is favorable for the rook. Black should stay and wait without exchanges.} 22. Qxc5 bxc5 {Probably Black missed the next little combination when he played 21. ..Qc5} (22... dxc5 $2 23. e5 $1 Rxe5 24. Rxe5 Nxe5 25. Rd8+ Kf7 26. Rb8 {With wins with the collapse of the queenside pawns.}) 23. Ne2 {White plays simple and strong. He threat 24.Nf4 and 25.Rxd6} d5 $2 {A mistake in a difficult position. Better was} (23... Ne8 24. Nf4 Re7 25. Kf2 {White can slowly improve the postion of his king and pawns in the queenside.}) 24. Nf4 {All these exchanges are in favor of white who will reach winning endgame.} Re7 25. Nxd5 Bxd5 26. exd5 Rxe1+ 27. Rxe1 Nxd5 28. Re6 {Here we are. Materially it is balanced but the white rook dominates and blacks weakness will come under strike.} N5b6 29. Re7 $1 {Again good move which cuts ogf the black king.} h5 { What else? There is no move with the knights or the king...only with pawns and so they become weaker.} 30. Kf2 Kf8 31. Re4 (31. Re6 $1 {was the more precise move which will freeze all black forces.} Kf7 32. Rd6 g5 33. b3 Ke7 34. Rg6 { and winning}) 31... Kf7 32. h4 Nf6 (32... Nd5 {is not so much better because after simply} 33. Ra4 Nb4 34. c3 Nd3+ 35. Ke3 Nxb2 36. Rxa6 {white is on the top again.}) 33. Re3 Nc4 (33... Nbd5 34. Ra3 Nb4 35. Kg3 Nxc2 36. Rxa6 {and the 'a' pawn is too strong for the knights.}) 34. Rc3 Nxb2 35. Rxc5 {and now there is no chance for a good outpost of the blacks knights. The rook dominates and Black is lost.} Nd7 36. Rc7 Ke8 37. Rc6 a5 38. Rxg6 Nc4 39. Rh6 { If you can always take material.} a4 40. Rxh5 a3 {Tries to create a last contra chance but there is no chance at all.} 41. Rh8+ Kf7 42. Ra8 Ndb6 43. Ra7+ Kg6 44. g4 {The rest of the game is a simple matter of technique and does not require further commentary.} Nd5 45. Ra6+ Kf7 46. h5 Nc3 47. g5 Nxa2 48. Ra7+ Kg8 49. h6 Ne5 50. f4 Ng6 51. f5 Ne5 52. Kg3 Nc3 53. g6 Ne2+ 54. Kf2 { Good victory for white in one 'standard day in the office'} 1-0
