progressBTN vs CO open at 50 BB
8-max MTT · ante 12.5 % · chip EV
BTN facing a CO open at 50 BB
The cutoff opens to 2.1 BB and the action reaches the button with 50 big blinds. The book folds 76% of hands, calls with 13%, 3-bets to 7 BB with 11% and goes all-in with 0.1%.
Always 3-bet: AA, AKs, AKo, AQs, A4s, A2s, KK, QQ, JJ, TT, 98s.
Always call: AJs, ATs, ATo, A9s, A8s, A7s, KJs, KJo, KTs, KTo, K9s, QJs and 4 more.
The button is in position against the raiser and only the blinds are left behind, which is why it calls far more often than the blinds do.
