This page does not ship a 13×13 Nash chart and then pretend it solved Hold'em. Antes, ICM, and the specific calling stations in the blinds move every cell. Use a real chart or a solver for the pixels. Use this to understand the shape before you memorize one.
The idea, not the religion
When you jam 10bb UTG, you are not "representing aces." You are putting a price on the entire table that only big pairs and strong aces should call. When you jam 10bb on the button, the blinds have to wake up with a calling hand that can stand a 10bb raise into a dead pot. That is why the range gets wider as you go later. Position still exists when you are short. UTG 76s is still a fold. Button 76s is often a jam. Same two cards, different node. Full pillar: short-stack push-fold.
ICM makes this meaner. A chip-EV jam on the bubble can be a $EV punt. See ICM and the bubble fold that feels sick.
