STARS 100+9 PLO. KT97ss.

[flawless_victory]

40 players, 30ish left. i have 5950 and thats top5.

blinds 25/50, i open pot UTG w/ KhTx9h7x. i know this is loose, dont worry about it. CO(9K) who is very loose and quite bad calls. he is the only player at the table who can bust me.
button(3.2K)call, he sucks as well.
ive never played anything but cash HE on stars, dont know these guys previously.
blinds fold, 3way.

flop come QhJd6d (T600)
i bet pot, CO calls, other guy folds.

turn is my best card 8h (T1800)
i bet pot again, he calls quick. almost defiantly.
i bet, he clicked call right away.

river, ugh 5d (T5400)
i have 3400 left, whats my play?
