The small blind with ten bigs is 111 hands, 59% of combos — and at the same time the biggest mass leak in tournament poker: most players shove here at half the width of equilibrium.
Push from SB, 10 BB stack
The range holds any ace and any king — from K2o — any suited queen and jack, tens from T3s, offsuit queens from Q6o, jacks from J7o, tens from T7o, connectors from 65s, and the gappers 75s and 86s.
If shoving K4o or J8o feels like suicide, run the numbers on the alternative. Folding surrenders half a blind instantly. You face one player who, at equilibrium, calls roughly a third of hands: two thirds of your shoves pick up a blind and a half with no showdown, and at showdown even J8o holds about 40% equity against the calling range. The total is comfortably positive — and unavailable to anyone "waiting for a hand".
What the ten took away against 8 BB: 54s, T2s, Q3o–Q5o, J5o–J6o — the bottom rim, nothing more. The "shove nearly everything" structure survives this stack too; it only starts to crumble in earnest towards 15 BB.
