How do I get expert analysis of a completed game?

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 the truly sound "best move" manner, or could I have made even better moves?

Can members suggest how I can get expert analysis?

post the game and maybe we can help you
