In the Benoni game, as far as i know, ...Be7 is ok. Ok, maybe its better on g7 but the bishop is not terrible on e7.

This game was kind of fascinating to me because I play the Benoni Defense.  The guy made a bad move with Be7, leaving him without counterplay if White plays properly.  You did and he tried in desperation to get counterplay.  This simply weakened his position and allowed you to win quite easily.
