Villain bought in just two orbits before this hand for slightly less than full amount and is playing one table only. Plays almost every hand and has open limped a few times. Also isolated a shortstack limper from the SB with A7o by raising to 3xBB (then check-jammed flop with top two and showed his hand when villain folded). Seems terribad.
