Live 40/80 hand

[tradingman123]

Borgata 40 game. Table is playing normal, maybe slightly on the tight side.

Villain in this hand is Joe (Korean guy) for those that play in these games.

Joe opens UTG, I call with 88.

Flop is K/3/4, rainbow. Ck/ck.

Turn is a 7. I bet, Joe calls.

River is another 7, what do I do? Bet/fold, ck/call, ck/fold?
