I've been wondering a long time about this. We're in NL SH.
I'm an avid 3better on the BU, I 3bet with a polarised range, meaning with my monsters QQ+ AK and my bluffs 78s A2s etc.
Let's say we're in this situation: CO is a tight reg who opens quite a bit from the CO, folds a lot against 3bets (+85%) and 4bets unusually tight. So I'd 3bet the guy with a bunch of air and quickly get away if he 4bets me since it's most of the time KK+ AK, sometimes QQ. I call with all my hands that are in front of his range (any PP to JJ, QJs+, ATo+) except for my monsters.
Let's say I've 3betted him 3 or 4 times over like 50 hands and he always folded. When I get QQ for instance I always wonder what's my best move. Should I think he knows that I'm 3bet bluffing a lot and expecting him to make a move right about now or do I think he's a robot that will fold again to my 3bet. Of course I will just call if it's the latter, or 3bet if I think he's going to make a move, but it's still an uncertain spot.
So my question is: would you guys keep 3betting the guy and shove against his 4bet with QQ expecting him to make a move, would you guys 3bet/fold or just call in these situations? So overall question what's more important history or stats?
