25bb push/fold chart with a 1bb ante
Even at twenty-five big blinds the ante keeps more than half the deck in the jamming range. As with the ante-free chart at this depth, treat it as a boundary marker rather than a recommendation: a strategy with a smaller raise available does better. What the page is really showing is how far the ante pushes the boundary out.
Small blind jams 52% of hands.
Big blind calls 30% of hands.
Loading the solved ranges…
These ranges are solved here rather than copied from a published chart. The solver runs an iterative approximation, so treat the overall jamming frequency as reliable and the exact borderline cells as the least certain part of the grid. Hands on the edge of the range are close to break-even either way, which is why they are also the ones the solver is least sure about.
