99 rivers boat

[KitCloudkicker]

10/20 full.

utg (plays fairly solid, is aggressive but tends to crawl into a shell when played back at) raises, 1 caller, I call next in with black 99, HJ calls, button (fairly aggro, range here is 77+, ATs+, KQs) 3 bets, all call (anyone cap?). 5 way.


Flop is K22, two hearts, checked to button who bets, everyone calls.

Turn is the Jh. Checked around.

River 9d. UTG (PFR) bets, next guy folds.

Question 1: wtf does UTG have?
2: raise or go for overcalls?
