EvilEcstasy_ ???

Well, he's telling you he has a hand, problem is what hand? His raise preflop says overcards, overpair, medium/small pair. I don't put him on the str8 or the 5 but the flush draw is a possibility. You are only in bad shape against the overpair.

I think you either move in or fold the turn here. Not moving in is going to definitly get you to the river and what do you do if another spade hits the board? I would also not be ashamed to fold there.

His turn raise is scary. Is he trying to scare you off your hand but too afraid to push b/c he is on a draw? Does he think he has a lock on the hand and he's just trying to commit you to the pot? Is he semi-bluffing w/ a good draw?

Definitely a push or fold situation if you call you have 1/2 your stack committed to the pot. If you think you hand rates a call then it is an easy push expecially with the draws out there. I move in.

Push or fold situation, and I'm leaning towards a quick fold here.
