Depends on the crap hand. Anything that has a reasonable chance to turn in to a monster(74, 45, 46 etc). I play. They have outs when you get your draw and not a friggin person ever expects these hands if you hit 2 pair when their A horrible kicker drops.

The way I play is I will call only the BB with a large number (5-6) limpers (these are drawing hands remember). And fold to any raise except a MIN by the BB that makes it back to me. This is of course at a full table with standard # of fishy players and such.

2 fishy limpers and the rest folds I'd probably raise 3-4xBB to try and take it down here, or set up to rep that A when it falls, OR I hit and watch the complaints about the bad beat as they reload their stacks

I love poker
