Operation Winning is a Habit

Up a BI in two short sessions, one last night, one this morning. Thanks to this hand. Stats don't matter, he's tilting. And he's run this shove over line several times on me and others at the table. I stacked him HU originally for 1/4 BI to start the tilt, then he bought in bigger.

any reason for being 78bb? Arent you potentially missing value against BB by not being 100bb deep with him?.
