HU 25/50 really weird spot deep

[gergery]

I think he's got to have a flush the vast majority of the time. he'd be crazy to run big check-raise bluffs out of position that offer you 4:1 much, and his reraise range on the flop should include sets more than weaker flushes. actually, if you are agro, his range should skew even smaller as he'll make more on check-raising the turn and not letting you get away from weaker flushes, bluffs and missed sets.
