No one's checking behind on this river here are you?

And if you choose to value bet as I did, you're not folding to the all-in check-raise, right?

I call and do a fist pump

I make a bigger bet on the river with your hand. My bigger bet makes a call obvious. However 2nd nuts there can't really fold, too many guys like this proving a fold would be a horribly -EV play.
