Villain is an unknown... Pokerace is down so I dont have stats but he seems like a decent TAG, and he's not overly aggressive... not one of those TAGs that 3 bets everyone etc. I almost raised pre-flop since villain posted but opted not to since the [censored] regular shortstacker likes to limp-shove.
