trips with top kicker

PokerStars 0.25/0.50 Hold'em (10 handed) converterPreflop: Hero is MP3 with [As], [Kh]. 2 folds, UTG+2 calls, MP1 folds, MP2 calls, Hero calls, CO calls.Flop: (17.40 SB) [2c], [Ad], [Ac] (5 players)UTG+2 checks, MP2 checks, Hero bets, UTG+2 folds, MP2 calls, Hero calls.Button 3-bets preflop, then caps this flop. He's a little loose, so any AK-AJ is possible. Guessing the others are on draws, flush is the most likely.Turn: (16.20 BB) [Qd] (3 players)MP2 checks, Hero bets, MP2 calls, Hero calls.Well, he caps again. Was I was completely right in 3 betting this?River: (28.20 BB) [Jc] (3 players)MP2 checks, Hero checks, Button checks.Final Pot: 28.20 BBMP2 was obviously on a draw, and the most likely was a flush draw (who'd go this far with a gutshot), so I figure his check is begging for another round of raise/raise. The button has me worried, because I put him on 3 hands on the flop, 2 of which have me beat and one that splits the pot. Now, I'm confident checking down here was wise, please let me know if it was a bad play. My question is this: If button bet behind me and MP2 raised, would I have to let go of the hand, knowing it will probably cost me 4BB to see, or would calling it down no matter what be in order here?

I think checking through the river is okay... I don't like giving fishies the satisfaction of making their hand on the river and then attempting a check raise. If it were any other card, I think I'd cap the river again and just pray my opponent doesn't have a boat. When you think about his possible holdings here, you're either splitting or beat badly. The preflop three bet and continued aggression screams, ak, aq, or qq. I think you're probably praying for a split here. IMO you're either splitting or beat. But since he checked through the river, flush takes it?

its a split pot. I would have checked the river, too.

Still, the question remains.. If I checked, button had bet and MP2 raised, what would you do? Call it down, even though it will likely cost 4BB?

I dont think its a split pot.

If its not a split then MP-whatever wins with his flush.

right. But what flush can you put him on here?KQs really seems the only viable option unless he is a fool.and i think he leads the turn with that hand.you might be right, its probably split

Ok, enough debating what they had.. Button had AK and MP had 34o.But my strat question remains:

 If I checked, button had bet and MP2 raised, what would you do? Call it down, even though it will likely cost 4BB?
