really bad play since i lost the maximum here : i alwys end up in trouble in this kind of hand especially vs Short stack.
how do u play this? i feel a turn check and calling medium size bet on river is a decent option.

I wouldn't say it was a bad play. I think you played it fine...just bad luck I would say.

Read on the opponent is pretty important in a situation like this one. If opponent is a CS, aggro player who hasn't shown any strength PF, I'm betting the whole way. If it's anyone else, I'm slowing down on the turn and calling a reasonable bet on the river like you suggested.
