Fist pump shove

I would callanyway, I don't think he would check-raise a flush on river, because you didn't showed aggression on flop and turn

I def agree with flat calling here.  He could have a flush a decent percentage of the time, and if you rr its unlikely youll get called by any hands you are beating (unless he is just lol bad).

I had a huge comment ready about 2 pairs and straight draws then looked over the action again and saw that he c/r the river (i thought he donked out).  In this instance I agree with the flat call, I think this is a flush more often than not, but it's a bluff enough of the time to make a call profitible.Additionally, lol @ c/r when he makes the flush on the river, and sick spot for you :(
