Wasn't sure if this check fold is correct.

His stats were 32/11/7

If I do pro poker tools My hand vs an 11% villian Range on this flop I have 34% equity

If I do my hand vs 8% villian range as he opens utg, and exclude AA as he sometimes 4 bets I have 31% equity

At 1.71 SPR I need 39% equity is that correct?

However when I bet he folds sometimes and I have fold equity - when he calls I have less than the quoted equity because he folds his low equity hands.
So what value do I use for stack off equity required to bet?

I'm trying to work out how I'm supposed to think about this type of spot?

Interestingly If I have the Ac instead of As my equity only goes up from 31% - 33% (for vs 8%!aa range) but now should I bet because I block a lot of his continue range?


Thanks

Check fold seems ok as played.

There might be some bet/fold lines that can work but not easy to optimize. For example, Hero can bet 15 and jam some turns if called.

Well played.

Do I bet if I have the Ac?
