I'm getting a little more than 3-1 to call, but the bet is almost 1/3 of my stack. If i had a smaller stack, i could easily push, but if i get all in i'm getting almost exactly 2.5-1 which is break even odds for a flush draw. If he doesn't have the ace, maybe he folds, but probably not. Push or fold? Or call 1/3 of my stack?

I didn't really have a read on this guy. Again i have an inside straight and backdoor flush draw. If i check, he will probably bet and i don't thnk i'll be getting proper odds to call. If i bet any amount here i am basically committed to the pot. I have a relatively small stack, and a decent chance of winning. Plus there's some chance he folds if i push. Should i push or fold?
