Under the Gun Push/Fold Range at 12 BB with BB Ante (9-Max)

Push 12% of hands

With a big blind ante, Under the Gun shoves 12% of hands at 12BB in 9-max — 4 percentage points wider than the 8% no-ante range.

Marginal hands on the threshold — A9s — can go either way; the Nash solution mixes them, so a consistent default (push or fold) is fine in practice.

The ante brings 9 more hands (58 of 1,326 combos) into the shoving range, including ATs, A9s, KQs, KJs, AJo, ATo, 66, 55.

12BB means every player starts the hand with 12 big blinds, before the blinds and the ante; the Big Blind pays the ante out of its own stack. The ranges are chip-EV Nash equilibria with no ICM, solved from 1 to 25bb against the Nash calling ranges of the players left to act. Under the Gun 12BB chart with no ante
