6bb push/fold chart with a 1bb ante
Add a one big blind ante and six big blinds becomes nearly the shallow end again: 92% of hands jam, against 79% without it. The ante is dead money in the middle, so the same shove is now risking the same stack to win half as much again, and hands that were marginal become clear. The big blind widens too, to 83%, which is why the jam is not as free as the raw number suggests.
Small blind jams 92% of hands.
Big blind calls 83% 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.
