Drill the short-stack shove decision — folded to you, do you move all-in or fold? Graded by position and stack, with the full Nash-style shove chart revealed each hand. Free, no signup.
A teaching model of unopened shove ranges — wider as your stack shrinks and your position gets later. Great for the ~5–15 BB tournament zone.
Under about 15 big blinds, tournament poker collapses into one decision made over and over — shove or fold. Drilling it is the fastest ROI in the game.
Once your stack drops under about 15 big blinds, most hands become a simple binary: when it folds to you, do you shove all-in or fold? Get this right and you stop bleeding blinds and stop busting with the wrong hands. It's the single highest-frequency decision in tournament poker, and it's almost entirely a memorisation-and-reps skill — which is exactly what this trainer drills.
Two things widen your shoving range: position (fewer players left to wake up with a hand — the button and small blind shove far wider than under the gun) and a shorter stack (less fold equity needed, and folding bleeds you out anyway). This trainer's chart shifts on both, so you build a feel for how the range breathes. When the money matters, layer in the ICM pressure from our calculator and the full tournaments course.
Deal, decide, see the whole range, repeat.
You get a random position and effective stack, folded to you, with two cards on the felt. This is the unopened-shove decision.
Make the call. Your score, streak and accuracy track how sharp you are — beat your best.
Every answer reveals the full 13×13 shove chart for that exact position and stack, with your hand highlighted — so you learn the range, not just the hand.
Hit Next hand and keep going. A few minutes a day and short-stack shoves become instant.
When your tournament stack is short (roughly under 15 big blinds), raising and then folding to a re-raise wastes chips. So you play 'push or fold': when it folds to you, either move all-in or fold. It simplifies short-stack play into one clear decision.
Around 15 big blinds and shorter, and especially under 10. The shorter you get, the more it becomes your only sensible option — a min-raise commits too much and leaves you no fold equity.
The later your position, the fewer players are left behind you who could wake up with a big hand and call. So the button and small blind can shove a very wide range, while under the gun you shove tight — several players still have to fold.
It's a teaching model that captures how the ranges move — wider as your stack shrinks and your position gets later. It's directionally aligned with Nash push/fold charts and ideal for building intuition; for exact solver ranges near ICM spots, use dedicated software.
