This hand is from DeepStack Table with ante.
Villan is thinking opponent, I would classified him as loose-agrressive. At the time when we played this hand I think he was trying to playback at me after I've won few hands against him.
Flop: He raised me second time at dry board , so I decided to call with A-high - I think he is raising with air.
Turn: I pick-up gut-shot and have two-overs, I'm still convinced that I have better hand.
River: I was thinking for long, because would he shove with flush rather than raise to $10-12 for value?

*I know playing abc I should fold on the flop, but what will You do when you have reads and put opponent on a bluff?

For me the only hands that fit both the flop raise and the shove are 75 & 53 suited hearts. Even then shoving the full monty on those hands when you could have the ace flush is brave. I would think some of the time these low flushes are content just to call on the end. A king flush combo with what is available doesn't fit the flop raise for me.
There is enough wrong here for me to suspect a bluff and call especially if you think he's tilting.

I would say a set or k9offsuit
