Nice game! Yeah, letting that knight on e4 was unfortunate, but it didn't matter, after the queens came off you just ended up with a winning endgame due to the pawns...
You had quite a bit of pressure before the queens came off, the knight was a nuisance, but it seems taking the queens off was a huge blunder. Not only did it make the pawns more powerful, but it dislodges the knight temporarily as well, and after c4, its definitely not coming back to e4 anytime soon. Well played, very instructive...
This is a game I played earlier today. I'm posting it for a couple reasons, the primary one being the fact that this was one of the few games where I had complete silence and could focus specifically on the game. It was also the highest rated opponent I had ever played, so the accuracy of his moves would be greater than any other game. Anyway, I went through and anayzed the game, so if anyone else could add or correct the way I evealuated positions I'd be grateful.
