I am not really confident in 3 bet pots yet, i have to work on that, that's why i called in this situation with 55 in position to see what can i do and to get some experience. I didn't really had a plan for the hand preflop 
i only knew i have to fight back in these situations sometimes.
On the flop after his cbet i thought i would try to float him. But on the turn he shoved so i folded. There was only potsize left, so maybe my float would be a simply push instead.
As you can see i need some training on this, so tell me what would you do in this situation.
Thanks,
