q49z321: ???

why would he push if he hit the fd there? you call or fold here?

I hate to call here but I hate to fold, too.
He might have slowplayed a set on the flop and now pushes, fearing flush and straightdraws. He also might have only AK, KK, JJ, KQ, QT, KT etc. with one diamond. Or even hit his fd an wants to trap you with his push.

I think I will close my eyes an hit the "Call"-Button, but I don't know if it's the right play.

well, i held my breath and clicked the call button. then i won a "massive" pot and was really happy for a couple hours about my awesome call, but then i started to wonder if it was even the right call at all. i could've easily been smoked, maybe this is just a situation where calling and folding are equally good optoins. that doesn't make sense. poker is confusing.

Nobody at 5nl is overbet shoving when they make their hand. Checking (slowplayyy it works at wsop!) or another $1 bet is far more likely.

Fold top 2 there never.

id have called simply because as you said, pushing makes no sense.
