Villain flats 48% and 3bets 33% from BB over 55 hands
I interpreted villains donk as 8x, didn't feel comfortable flatting (only really happy hitting 9 or A) or jamming as I didn't think I had much fold equity
However I still think folding flop is a decent mistake
flat flop and do something else than folding on A/T/9/spade turns. maybe even bluff some other broadway cards depending on his action/timing/sizing ott.
