two pair river action

[jba]

I had been playing HU with villain for a few hands and nothing really interesting had happened, but I'd been folding a lot. we've played a bunch before, he seems somewhat reasonable. now it's three handed.


fishy button open limps, villain completes, I check K5s.

flop: K5Tr
check, I bet, fish folds, villain calls

turn: 2r
check, I bet, he calls

river: 8
check, I bet, he raises, I ????
