how to play LA maniac lucky idiot?

[snake_oiler]

how do you play against a loose aggressive maniac idiot who's very lucky? i'm at a table with a guy who plays 85% of his hands, raises and reraises with crap like 72o...and he makes sets on the river with the weakest of hands, and flush after flush.

do you walk away or just play really tight until his luck runs out? i mean, he's got money and he's willing to throw it away, but you can't read this guy at all...how do you read a hand on a guy who reraises with 72 offsuit and NOTHING - not even a bottom pair - at the turn??? i want to be there when his luck turns, but i don't want to get killed in the process...

if you flop a good hand, like TPTK, do you just call him and assume he's playing crap again?
