The converter didn't like this hand very much at all.

What's the play here? I'm getting like 4:1 on the call and I'm sure I'm seeing lower aces and assorted crap enough to call it profitably, but what really makes this hand bad(to me) is the size of the pot on the flop, and I don't like my line.

Anyway, this situation happens to me fairly often, so my question is more about general principles than this specific hand. Huge multiway pots means no opportunity for error as a PSB is half my stack. Should I be trying to limp with AKs in L1? I limp the pot is only t60 4way, so I can get away from this hand if I'm beat.
