How SB opens at 15 BB
When the action folds to the Small Blind with 15 big blinds (8-max MTT with ante), the book plays 84% of hands: a raise to 2.5 BB with 2.0% and all-in with 38%, and a limp with 44%. The other 16% fold.
Always raised: Q7o.
Always all-in: AQo, AJo, ATo, A9o, A8o, A7s, A7o, A6o, A5o, A4o, A3s, A3o, A2s, A2o, KTo, K9o, K8s, K8o and 30 more.
Mixed hands (the book splits them between actions): AKo, ATs, A9s, A8s, A6s, A5s, A4s, KQs, KQo, KJo, K9s, K2s, QQ, QJs and 19 more.
At this depth the open is a small raise, with some hands going all-in directly.
Next to it at 15 BB: BTN 39%. 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): 72s 58%, 54o 64%, 62s 30%. These are the hands worth drilling, because a small change in the opponents or the stack flips them.
