bet .75 on the flop, so that if UTG shoves youll have the option to repop. plus the board isnt exactly drawy.

seems played fine, im calling the shove

i think a fold is best

although given the aggressiveness of villain, its slightly slightly possible villain is bluffing with a missed flush, but you prob have to fold majority of the time

I disagree that fold is best. Maybe against a TAG with a 29% river aggression or something. But against 83/17/3 over 40, I would call here with like KQ, much less Q7. I mean, c'mon, this dude seems like a total monkey. I think we can make a case for check/calling this river in the first place, therefore a) inducing a bluff b) keeping the pot kinda small. However, as played, this is a definite call for me.

def not a call, villain is not holding a Q, not bluffing a missed flush draw, villain is loose enough to be holding a 2 and his aggression would have maybe caused him to RR at some point before the river with QTo+

2 v 2, any other opinions or is this just a really marginal call?
