How SB opens at 19 BB
When the action folds to the Small Blind with 19 big blinds (8-max MTT with ante), the book plays 87% of hands: a raise to 2.5 BB with 7.2% and all-in with 26%, and a limp with 53%. The other 13% fold.
Always raised: KQs, Q8o, Q7o.
Always all-in: AJo, ATo, A9o, A8o, A7o, A6o, A5o, A4s, A4o, A3s, A3o, A2s, A2o, KJo, KTo, K9o, K8o, K6o and 10 more.
Mixed hands (the book splits them between actions): AKs, AKo, AQs, AQo, A7s, A6s, A5s, KK, KQo, KJs, KTs, K7s, K7o, K6s and 27 more.
At this depth the open is a small raise, with some hands going all-in directly.
Next to it at 19 BB: BTN 41%. The small blind only has the big blind behind, but it is out of position after the flop, so it mixes raises, limps and all-ins instead of simply opening wider.
Closest decisions (the book opens them only part of the time): 93o 54%, 64o 66%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
