fold pre... we are OOP, suited 3 gapper is bad in general.
dont check dark, just check. people gets suspicious when suddenly we show aggression after checking dark.
turn, easy shove due to image, pot to stack size and he aint going anywhere.
having K9 as a blocker here we can safely eliminate KK & 99, so he probably have AK here most of the times. 33 isn't normally a 5x open from a solid player UTG.
I think this hand is just too weak to play preflop to a raise, especially OOP, plus has high RIO (which is why I don't play 3 gappers). Easy fold, imo.
Never check dark. Why purposely forfeit an option?
I would have donked the flop and hope there's a big K out there that can't fold.
I don't understand our check/raise play (again, checking dark is so bad). Are we attempting to get opponents to fold worse hands? When Villain calls our huge check/raise and continues on the turn, I'm actually starting to worry that we've been coolered. I'm strongly considering making a hero fold, although obviously this is a difficult spot with so much money now in the pot, plus our image.
ETA: Keep in mind that Villain was an overcaller preflop (I believe this changes the range most people are giving him).
