$10 NLHE 6-max: 150bbs deep - flat 4bet OOP or min 5bet

originally posted this in the microcrushers thread but lack of responses so anyone good with this?

No notes on what he 4bets. called the 4bet OOP planning on x/jamming a lot of flops. just thought b/c were 150 deep i didnt really want to get into his stacking range there cus i dont really know what it is and would rather keep his dominated bluffs in then get more value OTF.

prefer to min 5bet/call off, 5bet jam or flat?

I min 5bet call it off. We're out of position against a potentially fishy villain. His value range is never 4bet folding. When you have air in this spot do you fistpump bluff?
