you can play it this way or you can flat
your original raise had a lot of fold equity
after he 3bs you pretty much have no fold equity

so you need him to fold sometimes or have 42.5% equity in the pot or something
I think you have about 35% equity (he can also have T8 and AA here too)

so his flop and preflop sizing gayed it up for you since the pot was small on the flop
so kind of tempting to actually call the flop and c/c the turn as well because with the pot size this small you'll have more implied odds
