The iso pre is way too spewy. There is no way you will get all the players to fold and you'll be playing OOP for the hand. I would donk the turn and hope he folds. Though this will rarely happen you're going to call his bet anyway so if he ever folds its a huge plus

I like your thinking a lot, but you said this guy is a bad regular so he probably will not fold to a turn lead.  Being a bad reg, he might just see his two aces and go with it, but you have lots of outs, so I do not mind it.  Bad regs do not see your fancy plays, nor do they understand them after you beat them over the head with it. 

I say just lead into him, you are not folding to his bet on the turn if you check right? Does this guy ever check behind much? you want to stack him, so build it on the turn, if you brick the river, give up, you know he has aces, well 95% sure :)

I don't like the iso preflop.  I wouldn't even think of is as an iso raise, there's really no such thing in this situation.  You're pretty likely to get a string of callers and essentially all players acting after you on the flop.  Your hand is not really strong enough for that.

As it turned out, you got a bit lucky in a way that UTG isolated himself against you.  But you still end up in a pretty bad situation where you're probably putting money in bad a lot of the time.

On the flop... with this SPR, I don't see the merits of just calling.  If you want to play you should just get it in.  Problem is, you don't quite have the odds for that, especially when you consider rake.  I don't really see how there's any fold equity on this board against AA either.  So you kinda have to fold this flop, or accept that you're gambling with a -EV play.

As played, you're not ahead of AAxx yet, so you don't really mind if it gets checked through.  I don't think AA is ever folding to your bet here, so you don't really achieve anything by betting.  You'd obviously call if he bets since you get the right price, but you're also a 9:11 dog on the turn so you shouldn't be super excited about it.

As it turned out, you got a bit lucky in a way that UTG isolated himself against you. Agree` preflop agree

disagre with~   But you still end up in a pretty bad situation where you're probably putting money in bad a lot of the time.~ u re in 5 bet pot and have enough equity to stack off vs AA ~ shove on flop

because on flop some nittier player if he doesnt know you might give credit to your reraise allin where will you gain some little fold equity, plus your outs stand as they stand, on turn, its much more likely that you are representing exactly what you do have in hand, so if you got to that point i woulda consider check the turn and realise equity because i dont think you gonna get a fold on turn, tho allin isnot as bad. your equity isnt poor

Ok,tnx for answers. Definetly agree for preflop that is spewy bcs they never folding practicaly anything.
When he 4bets me I must call and that is completly "standard" ( I dont like that word :) )
When flop comes I have 35-40% eq against him. Thats not bad but I planed if turn hit 5-T I will donk out and try to him fold his hand, now question is what is best play if turn lets say K?

 I don't think AA is ever folding to your bet here, so you don't really achieve anything by betting.

Well I would not be betting to get a fold, I would be betting to milk a little more out of him in case I hit the river.  If I check turn then bet river when I hit, do I get called?  Maybe even a bad reg can see that one.  That turn looks harmless, so if I bet it he may think he is still good.  I can always back off the river when I know that I missed, it is still one bet either way, but here (betting turn) it does not look as strong as waiting to bet river.  If I hit the river I can get two bets called ( the turn and maybe the river).

Pot is 85€ and he have just 42€ behind, if I dont bet turn he probably will.

overcalling is best of all. utg is too short to call him and make money of it (right me if i wrong)

as played, AI OTF. i think, we do have enough ev vs aaxx (38% vs random aces)

and yeah ,no FE OTT

"What do you think about my pre iso?"

It's not an iso raise when there's already 4 players in the pot, and you're OOP vs 3 of them. You have a weak hand that has to flop well to make money, and you're given the option to check and see a free flop. Just take it and go from there.

The way you played it, you did indeed manage to "isolate". The problem is you isolated yourself with a weak hand OOP vs an aggressive player. Not a good money-making scenario.
