Deep 100nl with one crazy villain

[MTBlue]

doesn't sound like a bad lag. Just sounds like he ran an aggressive bluff putting you on a flush when you minraised the turn. You'd be tough pressed to call there without the pure nuts or something close so its not a bad shove on the end.

If he hasn't gotten out of line except once its a clear fold. I play higher limits usually but when I drop down this is the type of stuff I love to pull. One obvious bad bluff double opponent up then double up and take his stack usually when he has an obvious overpair.
