Played a hand which to a large extent is just a bad beat but I wouldn't mind running it past you guys anyway. 

$250 6max tournament, blinds at 15/30, 5k Starting Stacks. I open to 75 with KK in CO, BTN is good aggressive reg 3Bets to 190, I 4Bet to 550, BTN flats. Flop is 942r , I CBet 550, Call. Turn Q, I bet 1175, Call. River 9. I feel like this is a pretty bad card for me actually as I think the Villain can definitely have a 9 in his hand quite a lot the way the hand has played out. I move all in for 2800 effective and am shown the J9s. 

I think my opponent does have a lot of suited 9 combos, as well hands like TT, JJ, AQ. I don't really think he has that many sets given the action. Is jam river the only move here, or would anyone ever play it any other way? Villain and I have reasonable amount of history and I think view one another as being capable aggressive players.
