Funny, I have been struggling with this very question regarding AK. Lately I have been pushing if there is any significant money in already to pick up or the blinds have gone up to make them tasty to pick up. So, say we are in Level 2 and there are 3 limpers and I am SB. I'll push and take the t135 most of the time. Occasionally a jackass will call with AQ or 78s or something and I'll usually double up. Is this a bad strategy?

When there's not enough to push, the big raise followed by c-bet has been working really well for me. If the flop missed me it most likely missed villain and they are afraid I have a high pair. I think it is very positive EV to play it this way.

Then again, I'm playing at $11s, so there you go.
