Strategic game (repost)

I played this game after being exposed to heavy rain during intermission between the two rounds. Having wet feet seemed to help as I finally played a game that I could be pleased with. In the opening my opponent committed a well-known positional mistake and then had a hard time escaping from the bind.It turned out though that converting the advantage was not as trivial as I expected.

Nbd2 Nc5 10. c3 Nxb3 This is a positional mistake, as now White's control over d4 and c5 becomes very firm. black now has 3 main moves 10... Bg4 11. Bc2 Be7 (11... Nxe5 12. Qe1)12. Re1 Qd7 (12...

Rxg6 Qxg6 now my main risk is that black will trade off the second rook the same way, so I tried to go back and forth, trying to make sure black rook is busy either guarding e6 or the a file 27.

Qf2 Ra7 38. Qh4 Ra8 39. Rg3 Qf7 40. Rc3 Bd7 41. Qg5 Qg6 42. Qe7 42. Qxg6 hxg6 now opposite colour bishop endgame has some promise if white brings king on b6 and takes on g7 with bishop, and creates passed pawn on kingside - but that's all very remote 42... Qe8 43.

47... Kg8 logical would be for black to take over the a file, but then I was hoping to generate enough pressure on kingside 47... Ra8 but then fritz finds a brilliant (but predictable) sac: 48. e6!!
