Getting Check-raised on the river.

[Huh]

Good $6-$12 home game.

One early limper to me in the big blind with black Jacks.

I raise, and it's heads up. Limper is starting to improve his game, but can be overly tricky at times. His hand selection is a bit questionable, but it's better than most at this game.

Flop comes down K55 rainbow.

He checks, I bet, he calls.

Turn is a offsuit deuce, he checks, I check.

River is a 9. He checks, I bet, he raises, I call.

Opinions on all streets appreciated.

Also, I was wondering what most people do if bet into on this flop.
