Queen's Gambit Accepted opening

Hi,

Previoulsy, I was predominantly a e4 player but recently I switched to d4 and offering queen's gambit almost every time. This is one of the games I played recently in which my opponent accepted the Queen's Gambit and though I was able to win the game easily, I think my opponent made few mistakes, specially the one on 23 rd step by moving f5. In my view, black should not try to protect the captured c4 pawn with b5 and a6 by doing so, it will expose it queen's side and in the mean time, white can activate it's pieces. Please review this game and let me know, the mistakes made by both white and black, so I can improve my game further with this opening based on your suggestions.

Thanks.

I don't play Queens Gambit but 4.Na3 looks just plain wrong, I suggest you look at some games where White plays immediately 4.a4!

I was wondering about this position:

Not sure if Black has some miracle save but Nxg7 looks standard.

3...b5 is horrible: Here's the trap it falls into

Geez, what's with people bashing on the QGA? It has a ton of good points, it's just not the most popular. The key is to not try to hold on to the pawn and set up your pieces to play against the center as white takes time to regain it. 3 e4 is most aggressive, but black has sharp replies to it.
