Drill PokerThe small blind with five bigs is the limiting case of push/fold: 143 hands out of 169, almost 80% of combos. Four hands out of five correctly go all-in.
Push from SB, 5 BB stack
It's easier to list what folds: the offsuit bottom with no connection and no paint — 72o, 82o, 92o, 62o, J2o and their nearest neighbours. Everything else is a shove: any king (K2o included), any queen from Q7o and any suited queen, connectors down to 54s, J4s, T8o.
Why so wide: against a single opponent the fold equity is large, half of your blind is already in the pot, and if you fold, one hand later you'll pay the big blind — a fifth of your stack — with no say in the matter. Shoving "junk" from the SB at 5 BB isn't gambling; it's collecting your own money back.
The spot's main mistake is folding "embarrassing" hands like T4s or Q8o. Over a month of tournaments those folds add up to a real loss the player never even notices: each one looks sensible on its own. The grid above is the best way to see the scale. How the picture changes as the stack grows — on the 8 BB and 10 BB pages.
