Prob best to flat the $60 raise then, as you might be inducing the original bettor to shove, thus creating better pot odds for yourself.
Problem comes if bb flats or folds, which is a lot more likely.
If we blank the turn we lose a lot of equity and may be a nasty spot if the board pairs. Also if we hit we might totally lose our customer as the 9 diamonds are deffo scare cards, making the pot alot smaller.
Thing is OP is quite shallow stacked so i think hoping for folding equity is quite optimistic. Obviously we are not passing the hand so maybe trying to get the hand 3 way to the turn would be optimal dont you think? I think we don't need to worry about reeling in a customer if we hit as we would only have $90 back and the pot would be $200+. Chances are a flush card could make somebody a pair + 4 flush, which they dont pass in live poker or even a 5 flush. And a Jack may well fill in those JT, KJ kinda hands.
