Nf3 Bf5 8. Be2 {I decided to keep the knight on c1 to avoid Nb4 and forks on c2.} Be7 9. O-O O-O 10. Be3 (10. a3 {Shyam suggested this. Maybe, but I should learn something against the Alekhine, I keep getting tough positions!}) 10... Nb4 11. Na3 Bf6 12. Qb3 {Qd2 was an option, but then I didn't see how to move Ra1 or Na3... maybe with Rfc1 and then Nb5 followed by a3.} a5 13. Rac1 Qd7 {This was a nice idea, but white seems ok.} 14. Rfd1 (14. Nb5 d5 15. c5 (15. cxd5 N6xd5 {I rejected this since it gave black a very nice outpost.}) 15... Nc4 16. Bxc4 dxc4 17. Qxc4 Bd3 {14. Nb5 had been my original intention, but I saw this line and didn't like it.}) 14... Qa4 15. Qxa4 (15. Bg5 Qxb3 16. axb3 Bxg5 17. Nxg5 { I didn't like this endgame.}) (15. Nb5 Qxa2 (15... Qxb3 16. axb3 Rac8 {This I didn't like so much.}) (15... Nxa2 16. Qxa4 Nxa4 17. Ra1 Nxb2 18. Rd2) 16. Qxa2 Nxa2 17. Ra1 Nb4 18. Nxc7 Rac8 19. Nb5 {This line seemed okay.}) 15... Nxa4 16. b3 (16. Nb5 {I didn't look at this too much since it seemed that too many things were hanging. But it is OK.}) 16... Nb6 17. Nb5 Rfc8 (17... Nxa2 18. Ra1 {Important is that Nb5 covers the c3-square.} Nb4 19. Nxc7 Ra7 20. Nb5 Raa8 21. Rd2 {This seemed good for white.}) 18. Rd2 {Now white is in control again.} Bd7 19. Nc3 (19. a3 Bxb5 20. axb4 Bd7 21. b5 {I briefly considered this but 19 . Nc3 seemed more solid.}) 19... Be8 (19... a4 20. a3 axb3 (20... Nc6 21. b4 {is progress for white.}) 21. axb4 {The pawn will be eaten.}) 20. a3 Na6 21. Ng5 { Idea to go to e4 and force the bishop back. Also opens up f3 for the white bishop (but moving the bishop away from the protection of c4 might invite a4-ideas from black.)} (21. c5 dxc5 22. dxc5 Nd7 23. Ne4 Be7 24. c6 bxc6 25. Rxc6 {Computer suggestion with huge pressure for white.}) 21... c5 22. Nge4 ( 22. d5 {Also considered this and just play with the space advantage.}) 22... Bxd4 {This loses a pawn.} (22... Be7 {This seemed best but very passive.}) 23. Bxd4 cxd4 24. Rxd4 Nc5 25. Rxd6 (25. Nxc5 dxc5 26. Rd6 Bc6 {Black hoped for something like this (still bad for him), but he missed 25. Rxd6.}) 25... Nxe4 ( 25... Nxb3 {Black had counted on this.} 26. Rb1 {Double attak on the knights.}) 26. Rxb6 Nxc3 27. Rxc3 Bc6 28. Bf3 Bxf3 29. gxf3 {Either recapture should be OK. Maybe Rxf3 is better as I need not stress. I thought the rook was better on c3 though.} Rc7 30. b4 {Another plan is to just march the pawn to c6 to get the 2v1-majority?} axb4 31. axb4 Kf8 32. c5 Ra1+ 33. Kg2 Rc6 {Tricky move!} 34. f4 (34. Rxb7 Rg6+ 35. Kh2 Rag1 36. h4 R6g2+ 37. Kh3 Rg6 {Will be a draw by repetition.}) 34... Ra6 (34... Rxb6 {I thought black should try to defend this. } 35. cxb6 Ra6 (35... Re1 36. Rc7 Re7 {Computer suggest this; seems to hold the balance.}) 36. Rc8+ Ke7 37. Rc7+ Ke6 38. Rxb7 {White probably wins here.}) 35. Rxb7 Rg6+ 36. Rg3 Rgf6 37. Re3 {Threatens mate.} g6 38. b5 Ra4 39. c6 Rc4 40. c7 Kg7 41. b6 h5 42. Rb8 Rcxf4 43. Re2 {Rxf2 is not really dangerous, but there's no reason to allow any counterplay whatsoever.} Rc4 44.
