[The Armchair]

I can't see how you'd not lose your stack here. I'd be more likely to push on the turn in response to his raise -- I'd put him on a K and think I'm head, and if he has a better kicker, I still have a ton of outs (any 4, 9, Q, or spade). As it turns out, you only had 8 outs on the river, but who knew.
