Push/fold is the only part of poker where every question has a correct answer. When the stack is short and nobody has entered before you, the decision comes down to two buttons — and for every hand, position and stack it is known which one is right. The problem is that at the table you get a few seconds for that decision, and knowing the table isn't enough — you have to answer without thinking. That is exactly what this trainer builds.
How the training works
The trainer deals a random hand, puts you in a random position — from early (EP) to the small blind — and gives you a stack from 5 to 20 BB. Nobody has entered the pot in front of you. You answer "push" or "fold" — with a button or the P and F keys.
After the answer, a 13×13 grid opens with the shoving range for that position and stack. Your hand is highlighted. The trainer shows whether the decision was right and explains why — in terms of the hand's category (pairs, suited and offsuit aces, broadways, weak hands) and the stack threshold: down to how many blinds this hand is still a shove from this position.
Borderline hands are flagged separately. If you folded A5o from the CO at 11 BB, that's not the mistake to fix first. If you folded 88 on the button at 9 BB — it is.
Score, streak and accuracy are tracked per session. The streak is the most honest metric: it resets on any mistake and only grows when you actually know the range instead of guessing.
What exactly you train
Three skills that usually get mixed up:
- The edge of the range. Not "should I shove AK" — everyone knows that — but where the range ends: K9o from the button at 10 BB is a shove, K8o no longer is. The edge is where the chips are lost.
- Position dependence. The same hand is a shove from the SB and a fold from EP. The trainer deliberately shuffles positions until this becomes a reflex.
- Stack dependence. The range at 7 BB is half again wider than at 12. Players most often err towards shoving too tight on a short stack — the trainer's stats make it visible within the first 50 hands.
A sample range
Position
Look at the small blind. Most players fold far too much here: against a single opponent, shoving becomes correct even with hands like J4s and K2o. If it feels like the trainer has "gone mad" suggesting such shoves — that's the most common reaction, and the most valuable correction.
What the trainer doesn't do
There are no spots with a raise in front of you (re-shoves), no limpers, no antes and no ICM. That's deliberate: the open shove is the base skill everything else builds on. Re-shoving and calling against a shove are covered on the chart pages; tournament adjustments live in the ICM trainer.
