My first hand on this table.
What do you do here? Do you raise/call or fold?

Without a read I probably fold here. Villain is pushing the turn with his 50bb-60bb starting stack and this really messes with your implied odds. Also, you don't get much equity from overcalls in this spot since when the other two villains still in the hand check/call, it's going to be with a heart draw that beats yours a lot of the time. Keep in mind that with those two players left to act behind you, when they check/raise you're sort of screwed.

If the flop was just me and zweiasse and we had 100bb effective stacks, I would likely call the flop bet if I knew he would pay me off well if I hit. However, with the overbet pot, Villain's small stack, and the two players left to act, I don't think we can call here profitably.

Yup, you are right, this is a clear fold with 2 opps still left to act ...
