That type of thinking doesn't happen consciously at the table when you have 30 seconds to make a decision. His PF limp to me indicated a small/medium pocket pair, which I think is the wrong move. A push with a PP is definitely the +EV situation because take this hand for example:

Limp in with 99, flop comes KJT, opponent pushes with T2, 99 calls (-EV) and loses

VERSUS:
Push with 99 as the favorite, opponent folds with T2 or calls with T2 and loses

But anyway, I'll ask him what he was thinking later on if I see him at the tables
