Missed to post my hand guys. It was QQ without the diamond blocker.
I will reveal the action.
I totally agree with the aforementioned posts. His 3bet vs my EP open and the pot bet on the flop (it was insta cbet) that shows he is ready to call a raise-shove for me, made me put him only in AA-KK and AKs with the diamonds. I think that I am miles behind in this spot. I folded. When he made that cbet he had only 0,70$ stack, but, still, 0.70$ are 0.70$ - about the 1/3 of my stack. Not spewing your marks here and there at the micros making nonsense calls, I think it's positive.
