Just play axb5
I Was so Close

why does everyone at that rating level just push pawns and then swindle points it was quite annoying when I was that rating

Whenever someone defend like that in QGA, you have to play axb5 first then Nc3. I prefer the Nf3 e3 line rather than e4 because it's easier to play and you can play b3 against people who play like this.

so they can't hold on to the pawn after e3?
they can hold onto the pawn and lose the rook/minor piece or lose the pawn

the only thing is that you won't get two pawns in the center in these lines since you are committing to e3 and e4 would be a waste of tempo
Had I won this game, I would have gotten to 1400 again. Unfortunately, that was not to be
Also, if anybody can comment on the opening (the QGA), I'd appreciate it a lot.
