His play is screaming flush draw that hit with the flop cold call then turn checkminraise pot builder. Have any background info like reads or past hands with the guy? I hate getting into places like this because the pot has just gotten huge after the only draw hit with you holding your dick in your left hand and TPTK in the other hand. Its either push or fold time. If you have a read that says your hand is good then push it now for sure.

I find a fold here against most normal opponents. The situation here is what allows stacks to trade hands - someone hits tptk, someone else hits the draw and tptk gets overplayed. I like to be on the receiving end of these stacks not the giving end.
