Push/fold ranges for heads-up. The chart on the front page is the lookup.
What is Nash, and what is push/fold?
A Nash strategy is a pair of strategies where neither player can gain by changing only their own. Push/fold means the choices are jam (all-in) or fold. There is no open-raise or postflop betting in these charts.
When should I use push/fold?
Often when the effective stack is short, under about 15 bb. Deeper stacks use smaller raises. These charts are heads-up only.
What is the difference between chipEV and ICM?
chipEV counts chips. Every chip is worth the same. ICM values chips by how they change a tournament payout. This app is chipEV, with no rake and no ICM.
How were these charts made?
The charts are heads-up jam/fold solves from our DCFR run on an exact 169×169 all-in equity table, every board, with card removal. The engine is poker_solver (MIT, © 2026 ashen). Stacks 3–15 bb, ante 0, 50,000 iterations. The 10 bb chart passed an independent CFR+ check on that same table. An outside published chart has not been compared. Ante other than 0 is not solved.
