its hard to pull off the runner runner flush for bluff. If it happens, awesome, but I am not going to put you on the spades. I would however put you on a straight with the 48 dollar raise on turn. If you spewed on river when a flush shows as it did, I would call the bluff with 2 pair or better. If you have the nuts, would you shove here? Some would 60-40 or less, but a value bet of $60 would make me think you had the straight and I might muck my 2 pair or better even with good odds. Seems to me, you represented the straight on turn and the flush on river. Its either one or the other, both, or nothing and any inconsistency will get you a call more often than not.
