what's best here? assuming some people are gonna be like "lolz ez shove" but I'm not sure how high my fold equity is in this spot and he might read a shove for what it is. tbh, this is another one of those spots that is just annoying for me b/c I think his range is pretty wide from Tx, oesd, flush draws, Qx, maybe set or 2pr. I'm guessin just callin the flop oop is no good, but what about a small 3bet to say like 40 or so? like if you guys had AA here and got raised, what would your line be?
