Criminal is a multi-tabling TAgg, plays a lot like you probably do if you're reading this. He's already picked me off once going after his blinds, so we've been going at it a bit.
MP is the table sucker, too aggressive, calls too much. ETA of about 1-4 orbits until he loses the rest of his stack.

Oh yeah, this flop float really really sucks...
