When it folds to the small blind you raise about 37% of hands (494 combos), up to ~45% with the mixed band. You already have half a blind in and only one player left to beat — but you will be out of position for the entire hand if the big blind calls.

The small blind is a strange seat: the widest single-opponent spot in the game and the worst position at the same time. You are getting a good price to attack one player, and the big blind folds often enough that a raise shows an immediate profit with a lot of hands. But if the big blind calls or 3-bets — against a small-blind open our reference big blind defends about 52% of hands — you play every post-flop street first.
That is why the range is wide but shaped differently from the button: it leans much harder on suited hands and on hands that hold their value out of position. Suited aces (all of them), suited kings down to K3s and the suited connectors are core opens; the weaker offsuit hands (K8o–K7o, Q8o, J9o, T9o, 98o) sit in the mixed band and are the first thing to cut against a big blind who defends aggressively — and offsuit filler a step below that (Q7o, J7o, T8o, 97o, 76o) is a fold here even though the button opens some of it.
The alternative strategy — limping part of the range — is genuinely viable and used by solvers at deeper stacks, but it is much harder to play well, and against most opponents a raise-or-fold strategy at this width captures nearly all of the available EV with far less complexity.
About 37% as the core raising range (494 combos), stretching to ~45% including the marginal hands solvers mix. That is much wider than any other non-button seat because only one player is left to act — but it is tighter than the button (43%) because you have no position post-flop.
A raise-or-fold strategy at around 37% is simpler and captures most of the EV. Solvers do use a limping range in deep-stacked cash games, but it requires a well-constructed follow-up strategy for every board — get raise-or-fold right first, and only add limps once the rest of your preflop game is solid.

Cash-game ranges are a curated GTO reference, drilled question-by-question in the trainer. The mixed band lists hands solvers play only part of the time; we do not have exact frequencies for it, so the percentages on this page count the core range and the core-plus-mixed width separately.
