Vilain german reg, seems good for what I've seen. He plays 33/25/2 over 400 hands, raise first in pretty wide in every position (he probably opens 30%+ UTG+1). Doesn't have a high 4b stat over the sample, but I did see him 4B/call 88 CO vs an aggro 3bettor BTN.
My image is very bad, I've shown a pretty crazy bluff BvB on another table, and been relatively aggro at this table (mostly been 3betting every open from the fish sitting at my right).

Definitely a marginal situation, but I feel with stack depth he'll be very inclined to 4b this spot a lot. And he's opening very wide in the first place. Considering how the session has started, I'm ok splashing around a little bit, keeping with the spewy image and hopefully try to profit from it at some point.

Once I pair my 4 I'm ready to put quite a bit of money in the middle. Already considering the possibility of playing for stacks here.

eff stack = pot bet (when we take out rake). Vilain shoves in 8-10 sec. Very close spot IMO.
