Mehrunes Dagon raises to $350 in a $10/20 game; how to respond?

Man, Oblivion is sooooo -EV

Anyway, I was watching this dude playing shorthanded 10/20. He was jacking it preflop to $150, $250, $350 with regularity. Raising more than 50% of hands. He'd go straight from $20 -> $300 too, these weren't reraises.

Saw him call an allin reraise with J4 after one of his preflop bombs, his $250 bumped to $900.

He had a biggish stack and would tend to fire big if he hit any part of the flop, then call an allin if he had anything.

None of the other players were really playing back at him preflop.

So, vs. this insane guy, what's the best way to play? Buy in with 2K, just wait for TPTK+, and try to double up, sucking up $250 preflop hits while waiting?

Or buy in for like $900 and try to get allin preflop with, say, A9+, 77+, KQ?
