Game is 2-5 400-1k buyin.
Vilain (covers, bought-in for 1k) is a 30ish white guy arrived 1 orbit ago, seems active, 3bet twice (once out of his straddle to steal dead money), didnt saw his hand once, no other info on him since new to 2-5, but he might be a reg, I'm a 1-2 player so he might think I'm scared money and try to make moves on me, but that's just assumptions...
Hero (690): 24 white guy, not very talking at the table since i'm trying to play my A-game and really concentrate when I'm taking shot at 2-5, before including table talk.
Hand:
Folds to Hero in MP raises to 20 with A
K

Flop (367): Q
