Was I wrong to assume I was 50% against villains range?
I'm trying to utilize Renton's chat log post into my game especially where he talked about 3 bettting with position against someone you think your hand is 50/50 against. So from villains stats what do you think?

I felt like it was a pretty standard fold. I'm representing quite a bit of strength by 3betting him and he didn't care. SO AA,KK, AK would be my guess at his range.
