This guy was playing aggressively, I didn't 3bet him because of ICM, But thinking know maybe if I had 3bet him I would have lost less cheaps because I would have fold to a 4bet all in. I think I should have check on the turn to control de pot. what about this hand guys ? I don't think he was bluffing me.

Guy was playing aggro... didn't want to 3b/f... then why not just jam pre?

Agressively but not crazy, I didn't say I didn't want to 3b/f, maybe was a better idea. I put in ICMIZER he oppening like 20 % of hands from utg that I think is huge amount and icmizer said only QQ+ should go all in. There was a guy with 2 bb alive )

Flatting pre is fine, 3betting is probably better though since you cover. But if you're plan is to 3bet/fold, then I prefer calling.

Bet flop bigger, like 2/3. There a lot of bad turns which we want to protect against, like an A/K/Q/6/5.

Check turn. As played, fold to turn check/raise. It's a horrible spot for them to bluff, and they can easily show up with A6, 66, or JT, which is obviously discounted, since you block some jacks. And since you say they're active, they could show up something like 56s/67s/86s. And you're folding to any river that's not a ten, which you're not getting the right price to draw to. And you can likely expect them to bet/shove the riv most of the time, which makes it best to just muck the turn.

So as played, it's definitely best to check back the turn to pot control and avoid situations like this. That way if you think he's bluffing, it's less of your stack to call off.

thanks for replying . Do situations like call on turn to see if he would slowdown on river ?

The concept has merit in general on boards where they're not repping anything/repping thin. Like rainbow unpaired boards, eg. 359T, where they can only show up with a few sets and nearly no two pair combos. But on boards where there is 4 to a straight and you, the bettor, have straights in your range, it's best to let it go. It looks so strong for someone to check raise a 4 straight board when they're raising into someone who could easily have it.

And because you're on the money bubble at a final table, there are ICM implications. You don't want to call on the turn and then potentially feel commited to a river bet with a hand that only beats a bluff in a spot where it's hard for them to be bluffing. It's best to play tight and fold rather than bluff catch in a marginal situation when your stack matters more.
