"vilain runs 15/12 and quite passive on ~100 hands
quite a nit fish"

fold flop

definitely fold flop, at the very best u chopping with AK. Passive fish is not turning his QQ into a bluff on this board.

I think you probably see AA like 95% of the time if you call, afterall it's a 3x pot shove

First I didnt like the 4bet flat rather 5bet but I guess it might be good vs this passive of a player. On the flop you are actuayyly not at the top of your range with this hand. You will presumably have TT,99 and QJs (depending on how you play them pre). Anyway despite your range here its an easy fold IMO. Not like this tight of a player is going to go crazy on a flop like this.

PF seems an easy fold.

Flop seems even an easiest fold. You split at best, sometimes he can show a worst hand, but it will be very rare.

I don't think a PF 3bet and fold to his 4bet is that bad to be honest, as gross as it feels. I suppose I might only fold with a few 100 more hands on villain though but it's close.

Flop seems like a super easy fold. I very much doubt your constructed range for villain here, a 15/12 won't be 4betting in position and deep with TT,99,AQs,KQo,K9s, and T9s really ever.

Guys ,i look for some help in this 200bb deep spot in BTN vs Blinds
do you have some literature for this subjekt?THX

if this game 100bb situation ,is super easy ,but this 200 BB is much more harder play good our strong range {AK-AT,QQ-99}

vs this nit easy fold to his overbetshove flop bet.
On a separate note, against this kind of player, I may choose to flat on the big blind.
