villain is 9/3 AFq 100 in 32 hands w/ 20% 3bet in blinds, no reads or SD.
when 3bet me i put him on TT+,AQs+,AKo. I 4bet planning to fold on a 5bet shove and hoping to make him fold AK,TT,JJ,QQ which will make +EV my 4bet when he folds these or if he calls and i hit K/A flop, case in which he probably aint calling anymore w/o a flop set.
his 4bet flatting range i suppose is TT-QQ,AK.
i have no reads, so all ranges are an assumption.
should i just flat the 3bet pre?
what would be the best line here? shove, raise/fold or call and c/f non A/K/diamond rivers?

I 4bet planning to fold on a 5bet shove

4bet/folding AK here is really bad, he's very unlikely to fold QQ-TT AK. If we 4bet we have to call a shove.

Flatting the 3bet is a better play as we keep his range wider + it's a small 3bet + position.

Personally I like flatting the 3bet with position and evaluating flop. As HD says, I would only 4bet if I was willing to call a shove.

Flop bet sizing seems a bit ridiculous to me but I sometimes see this line from fish who flop a set and think that any bigger bet will scare you away. Personally I'd still be calling flop and c/f turn and river unimproved. I might call a small bet on turn or river if I improve and the flush and straight draws do not complete.

I don't see a problem with raise/fold flop though as I also see this min bet line taken with the old "bet to find out where I'm at" mentality.

Frankly I have no idea of that is +EV or not though.
