Post it in the game analysis forum (http://www.chess.com/forum/category/game-analysis). There's a lot of good people that will review your game and give you advice.
You can also submit it for computer advice, although I'm not sure on the procedure for that.
Good luck and congrats on the win.
I am a relative new comer to Chess.com and have just completed a game which I won. My White opponent failed to challenge for centeral pawn control, and did not develop one Knight and one Bishop. He tried to play the game with just 2 pieces, another lone Knight and lone Bishop. And I was able to capitalise on his lack of a sound opening plan.
So I know I was allowed to play a good game as Black, and I made a single pawn move in the middle game, which was "2 moves in 1" (!) - it discovered an open diagonal for my Queenside bishop to move to the Kingside and join in the fun, and it hemmed in his lone Knight on his Kingside.
So did I capitalise in a truly sound "best move" manner, or could I have made even better moves?
Can members suggest how I can get expert analysis?
