History: I'm at the Hippodrome in Leicester Sq. Villain has been at my table for about half an hour. Early 30's ish, he arrived from another table with a big stack and is clearly familiar with some of the players and the waitresses. Has played almost no hands so far. Imo, your typical London nit reg.
Has been on his phone/talking to people so idk how he'd perceive me. I've been pretty solid so far though i guess.
He has ~£1600 I have about £900.
