What could I have done?
10... Na7 was probably not a very helpful move, kinda wasted IMO
im not very good at giving it to you move by move, but my overall view: black failed to make any significant counter attacks AT ALL! most of his counters didn't even attempt to take any material, he just gave and gave and gave and gave, the only "attacks" he made was offering trades (like the queen trade)
Is this live chess or "on-line" correspondence type chess? I like how you handled the opening.
I'm probably not qualified to say what you could've done better, but honestly I don't think you did anything really wrong at all. I don't get the idea behind Qe2. About that same time I thought you could coordinate your pieces to go after his king-- which I guess is what you were doing-- and then you started pushing your g and h pawns. You probably looked into that during the game and concluded that what you did would better. You handed central pawn tensions well and I bet a GM or computer would say you had an advantage since like move 6 and only increased it as the game went on.
Wow your opponent's play was atrocious. He should be the one asking for advice.
- On move two, 2...Nc6 (Chigorin) is a suspect defence to be handled only with expert gloves.
- On move six, 6...e5 is kind of forced, otherwise Black is worse, if he isn't worse already
- I don't get 9...a6 and 10...Na7 - useless decentralizing moves.
- On move 13 he hangs the h7 pawn
- And things just went steadily downhill
The antidote is 2...c6! (Slav) or 2...e6! (QGD) and Black's position would be alright. Unorthodox openings are risky for the inexperienced - stick to the main line, for now.
@musicalhair: LOL at move six. Clearly, one doesn't have to be a GM to spot such a clearly good position.
