progressCO vs HJ open at 20 BB
8-max MTT · ante 12.5 % · chip EV
CO facing a HJ open at 20 BB
The hijack opens to 2 BB and the action reaches the cutoff with 20 big blinds. The book folds 84% of hands, calls with 6.8%, 3-bets to 4.5 BB with 1.9% and goes all-in with 7.3%.
Always all-in: AKo, AQo, A5s, KTs, QQ, QJs, QTs, JJ, JTs, 88, 44.
Always call: AJo, ATs, ATo, A8s, KQs, KJo, 77, 55.
With players still to act behind, the cutoff needs a stronger hand to continue, so it plays fewer hands than the button does and prefers a 3-bet or a fold to a loose call.
