As for the preflop folding this from the SB vs an old white dude opening 5 spots off the button in a 20 game cannot be missing much value. Like, there are people I fold this against, and many of them are old white dudes. If you're unsure if you can hero fold here, that's all the more reason to maybe not play this hand.

All that said obviously preflop is "standard"

I didn't notice the gutterball. You are right, you can't fold the turn.

(Meeting me? Were you playing 15/30 at the Oaks in Emeryville?)

EDIT: Should say what I would do. The villain's pre-flop raise makes the turn raise look a lot more legit and not spazzy. So I guess I would x-f any river that didn't improve my hand. That said, I can't blame anyone too much for calling the river given the size of the pot.
