as played i think its fine if you have a read he bluffs river, but you should also note his bet size on the river sometimes fish have bet sizes for air, bottom pair, mid pair and tp, nuts etc, so be sure to take note of that as well. flop cbet is fine he can call with 7x 6x T8 J8 22 33 44 as well as some over cards that he does not 3bet, turn check is fine since Ax is in bunch of his floats, river is a bit tricky especially with 3 over cards to your pair and with a str8 draw getting there thats why i say how much does he bet with his air, but if you have a read go with it and if you wrong make and note and learn from it. What do other players think?
