It was a 3rd round in the new club, after 2 draws with lower rated opponents I needed a win. I got a kid, whom I played before and won. I had White, Ruy Lopez, Classical Defense Deferred. The book recommends 7. d4 with advantage.

The first pawn break came on move 12. Houdini recommends instead 12… Bxe3 13. fxe3 Ne7 14. Bxd7 Qxd7 with an equality. I could win a pawn after 12… d5 13. exd5 Nxd5 14. Bxa7 and then after both Rxa7 and Nxa7 I win e5 pawn. The difference with the line I played is that in this case the knight stands on d5 and in the game it would be a black queen defending e5 pawn. 19. Qc4 looked active, but 19. Rad1 Nd6 20. Nxd6 cxd6 21. Qd3 was winning a pawn.

Another pawn break came on move 32, also d5. I came close to winning a pawn, but didn’t play 36. Nxa6.  Getting two passed pawns on the queenside would give me a serious advantage despite of computer’s modest +1.05 evaluation. Computer also suggests elegant 36. Rxd5 Rxd5 37. Nxa6 with basically the same result. Then we transformed to a bit better for me R+N vs. R+N endgame, where I had to play Rc6 on move 44, not 45.

Then we exchanged rooks and came into an equal knight endgame. Move 62 was natural, but also provoking. Suddenly he took my knight. I had 1.5 minute left and needed to calculate that I at least will not lose the arising pawn endgame if I take the knight, otherwise I would have to take the pawn instead.  After I took his pawn my long time ago acquired knowledge helped me to win.
