Hello,
I think on the turn you have to check this. If you bet range flop(very high%), you just end up with too many overcards to ''7'' there (JTs-KQs, 98/T9 Q9/J9, some KQo, and much more) which can be bluffed this turn and have same qualities (a)not blocking villains folds: at most he should be folding with everything below KJs b)have equity when called - but quite low)

Yes your logic holds truth on the turn - that some better are folding and some worse calling but keep in mind that 65/54 are super often raising flop so we get calls from 44 only)

Here is a short, effective video on FE: https://www.youtube.com/watch?v=6QDTCIodjaI

I gave inputs of 110, 0, 160, and 8% in this calculator: https://redchippoker.com/fold-equity-calculator/ and assuming no further action (i.e. not taking into account you improving and villain ch/f weak Ax on river, you improving and losing to a set, better two pair, etc.) you need it to work 33% of the time on the turn given your equity vs his turn continuing range. From the video, if his turn continuing range is the 35 combos you listed out you would need him to XC, XF an additional 35*33%, ~12 combos to breakeven. Of course, this is only as good as your estimate of his flop continuing range and preflop calling range (e.g. if he has more AXo combos, he needs more XC, XF hands).

Thank u both very much.

is it a pre flop 3bet spot?
