Big overbet into me on flop

[ahnuld]

playing some party 400nl 6max. Villan is a weird player, probably bad, but noone has looked him up yet. Hes made a few big overbets, but I dont know if he does this with solid hands or what.

Anyways, I get QQ and raise to 20. Poster folds, villan calls in BB. Flop comes 854 rainbow. Villan bets 150 into the 40 pot. Effective stack size is 350 total.

If he's done this regularly I'd probably move in here. But your post doesn't give much of a feel for the frequency of his overbets or their circumstances.

He hasnt done it in any real pattern

Fold. Find a better time to get your money in.

Well it sounds like he has done it fairly often. If this is the case i'd probaly move in.
