Villain is unknown. Is my line/play reasonable or too spewy? I think that I've good fold equity on the river vs some Jx top pair combos like AJ, KJs, QJs. I am repping a flush. Also B50 only needs 0.5/1.5 = 33% fold equity to be profitable. Can I reach that or is my limit too sticky? What do you think?
