given that JT got there I suppose it depends quite a bit on how you play your AK/KK/AA combos (there's quite a lot of them combined and might make a significant difference).

I'd go much bigger on the flop. That sizing is even fairly small for 100BB stacks.
You're not getting called by worse often enough, so check.

You don't have to be worried about JT too much because most players only defend JTs. And he could have folded turn or river with it.
The trouble hand here is a flush; specifically KsxS.

3b small is ok IMO. But yes bet bigger on the flop. I think JTo is still in vilain's range given the small 3b and deep stacks. I guess we should X/F this river. Don't expect to get called enough river to make it a profitable bet.

What about pre? Isn't this a hand we shouldn't be 3betting vs someone who's very likely to play back as shown by his stats, especially when deep?

Seems an easy vbet, around 120€. Obviously fold if he raises AI.

He can call us with any 2 pairs (and there is an ace on the flop, we are deep, so he can have any aces up combo, especially AK). And he seems very stationny.

i would x/f and x/c rarely. he s not calling with  much worse imo out of dynamics. look at how he will view ur range if u bet 110$ on river.

ps: im  a nit
