hero? with my hand i block 2 combos KK and JJ, could 3b KK pre, and judging by he's 3bstat i assume he flats with JJ, could have 55 and AQd,Q10d, but i have no info that he plays draws fast.
what do you think?

bump.

get it in. if his got 55 its a cooler rarely has another set.
pretty standard shove.

Stove 55/JJ/KJs with maybe AQdd or QTdd and see if you have the equity to get it in. I think a lot of these guys flat flop with combodraws, but they can get raised pretty often aswell.
