Trips facing 1,5x pot bet OTR

Would be nice to see what was your thought process.
I'm usually folding preflop with AJo. You are playing 200bb effective, so don't expect MP to fold vs 3bets a lot in position. He has a range advantage anyway.
I would check flop or bet 1/4.
When he raises, I believe you have a hand to 3bet/fold this flop. MP should 4bet preflop with suited-connectors more than flat call. But of course, I don't expect this players to 4bet with speculative hands. So he can have some flushes (98s, T9s, JTs, even QJs). AA, KK should 4bet too. You block the nuts, you block AK. Sure, you'll often isolate against better hands, but being deep you can 3bet/fold for sure.
The thing is that I can't see him having many bluffs too. So it is a tricky spot.
He'll probably overplay some random hands, but it's better safe than sorry.

Turn is interesting. Check/call and fold river is probably ok. Check/shoving with a pair and a flushdraw after the flop raise his asking for trouble probably.
Now when he checks back the turn after raising the flop... that is a gold opportunity for you. He should bet his flushes, even AK 100% of the times here. It looks like he has your hand ♦
That said, I would call the river overbet. Turn check is the reason I would do so.

I think I would just be flatting AJo Vs mp opn when you are over 200bbs deep. OTF i would go smaller with my cb say 33% psb. I think the line villain has took here you will more often than not see him show up with a full house here imo the way he played it raising flop checking turn then when the board pairs bombing river, so imo you made a correct fold..

I think it's also reasonable to bet/fold the river for value. I expect he will only raise with better so deep.

Im 3betting pré aslwell.
OTR i think its a good fold

I am folding this hand pre. Not playing big stacks, but I feel that I wont have much FE and AJo is a bad hand to play OOP with big stacks even vs fish. OTR is close I think, he represents a FH and he might have one, flushes and better aces are also in his range. I don't know how often will he bluff with an overbet. I will likely call I think, but still it looks like a guessing game.
