Villian attempts to steal 21% of the time and folds to 3bet 74% of the time. In light of this is my 3bet pre correct.

Villian also had a 67% fold to cbet. I think my turn bet is correct because the fd doesn't get there and his range doesn't have many 10x because of the preflop action.

i think you're overthinking this and putting too much value on specific stats and not looking at the overall picture. there's more variables to the problem here, and your conclusion is too quick.

why is your 3bet correct based on the fact that he folds 75% of the time? it might be +EV but have you compared it to the value of flatting? the vast majority of your edge will come from playing postflop, not pre.

what sort of value can you get out of him if you flat and keep his whole range on certain boards? will he spaz out and jam with a lot of air on you on a 5xx board?

if you 3bet him, how often will he bluff or value town you on an overcard board?

i don't think your play is particularly bad, but i think you're approaching the game as if you can solve it with a few stats.
