Looking back over this I think I would have checked the turn 3 handed. I realize it's probably not the highest EV play, but I would rather keep the pot small when I'm in the dark. It was three handed by the flop so I don't think a bet would win it on the flop. Your hand would probably stay good on the river, and if it doesn't you can usually expect a large pot between the other two in the hand. I just feel that betting will only build a bigger pot OOP while you're holding an overpair on a pretty dry board where you don't beat much of his range.
