No stats on Villian. He limped in Ep. A set seems very likely. This is a very common encounter with AA/KK/QQ. Do most of you guys fold and if the stacks were smaller, then it becomes a push?

Fold. Both players showed strength, and I'm guessing that at $1/2 limits players must know what a $7.50 bet usually indicates. Well, they ignored it.

I'd prefer a read, but I'm usually pushing here.

No read, I fold.

No reads means that best case scenerio = open ended straight flush draw, which is less than even money. Let it go and look for a better spot. Try to gain more reads on villain in the meantime.

yeah i think i fold this to a likely two pair maybe a set. I think if this was 6max i would just shove
