No reads on BB but he hasn't played many hands and shorty stack is just shorty stackific.

I have a sneaky suspicion that the Beluga Theorem will be espoused by at least one of you. Also, is it a good sign that your game is coming around when you play ~1500 hands in a session get felted 5 times while ahead, never really win any big pots except for 1, and still come out ahead at 2.85 ptbb/100?

Thanks in advance.
