You don't give tournamnet conditions (other stack sizes, where the bubble is, etc), but just because he's an idiot for calling all-in with Q3o doesn't make you not an idiot for committing 2/3 of your stack pre-flop for no good reason. I know it's rare that we get to see post-flop poker in this forum, but, geez, why the hell wouldn't you just call here and play some poker?
