Studying short-stack play? Enter a hand, position and stack (in big blinds) and see whether the shove is correct — straight from the Nash equilibrium charts. No sign-up.
Once your stack drops to about 10 big blinds or less, a "normal" open-raise stops making sense: you're already committed to the pot. In this zone the mathematically correct decision becomes binary — all-in or fold. The ranges in this calculator come from Nash equilibrium charts, the mathematical solution to that game, by position, stack and table size.
Pick the table size, your position and your stack in big blinds (chips ÷ big blind). Type your hand: the answer shows whether it's inside the shoving range — and the matrix shows the full range for that spot.
Push/fold is the only part of preflop with an exact mathematical solution — and that's what you get here, no frills. Deep-stack ranges and responses to raises don't have a single answer; in Pokwise they come from tested strategy charts, always labeled honestly. Study material: use it before and after you play, never during a game.
