opponent is 18/15/3.5 with 1% 3 bet over 400 hands. His ATS% is 29%. Should we ever fold or just insta shove? My analysis is that I have good pot equity vs his entire range only if he raises with TT-JJ. Otherwise, my hand got crushed. Also, its likely that he slowplayed KK+ preflop given his lower 3 bet%.
