Drill PokerThe small blind with eight bigs is 127 hands, 69% of combos. Against one opponent, with half a blind already in the pot, the shove stays correct with two thirds of the deck.
Push from SB, 8 BB stack
The range's anchor points: any ace and any king, any suited queen and jack (Q2s, J2s), suited tens from T2s, offsuit queens from Q3o, jacks from J5o, tens from T6o, all connectors from 54s up, and the gappers 75s and 86s.
Players err here in both directions, but differently. The tight mistake is common and cheap-looking: folding Q5o or T7o "because the hand is trash" — every such fold hands the big blind a pot a third of which is already yours. The loose mistake is a single, conspicuous one: shoving the absolute bottom like 82o and 72o, which lacks equity even against a random call.
An important caveat: this chart is about open-shoving when everyone has folded to you. Limping strategies in the SB exist, but at 8 BB with no antes the shove is simpler and gives the big blind no free flops. The neighbouring marks are 5 BB and 10 BB.
