And here's the hand that i'll regret fer the whole weekend

The standard point to fold is the turn. Made hands that bet that turn beat you and the only draw (or almost the only one, except 35) on the flop got there. The only reason to continue is if you think he has air alot, and that is something only you can know. You will have to go on feel here, and probably make a really close decision on the river should you choose to continue (although villain should push about anyting he got to the river with, not all are capable of that. You should know if he is)
