Pay jump
A point on a tournament payout ladder where finishing one place higher pays meaningfully more, sharply increasing the real-money cost of busting just before it.
ICM pressure is strongest right before a pay jump, since the gap between the two nearby finishing positions is large relative to the chips in play. A short stack near a pay jump is worth more than its chip count alone suggests, because simply surviving past one more opponent locks in the jump, and a big stack should apply pressure harder here, not softer, since opponents can least afford to call off near a jump.
