LMAO. Sometimes you just have to laugh and shake your head and move on to the next hand/tourney. I mean, you raise 4xBB UTG and get 4 callers. LOL! They can't all have monsters.

Then, even funnier, you bet out 3/4th pot or so on the flop and NOBODY folds, not even BB who checked it to you. THEY CAN'T ALL HAVE TRIPS. Clearly you are looking at KKs, QQs, or JJs, or maybe all three. Probably the biggest threat is BB who may have called with 22-TT because of the chips in the pot pre-flop. I'd put him on 88 or TT. There MIGHT be another set in there somewhere. But at least a couple of these guys have overpairs.

Back to the original question, do I go broke? Tough spot, but the correct play is probably to check/fold the turn depending on action. While you are clearly dealing with a couple morons, one of these guys likely has you beat, and even if they don't there is no shame on preserving a decent stack for when it really matters.
