The button opens about 43% of hands (566 combos) as its core range, stretching to roughly 53% with the mixed band. Only the two blinds act behind you and you have position for the whole hand — which is why around half of all starting hands are in play here.

The button is the most profitable seat in poker for one reason: it is the only seat that is guaranteed to act last on every post-flop street. Position is worth so much that hands which are folds from the cutoff — Q4s, J6s, T6s, 95s, 53s, K8o, A4o–A2o — become profitable opens here, because you can see what your opponent does before you decide, and you can take the pot away on any street.
Two blinds means two hands to get through, and both of them are folding a big chunk of the time. That fold equity alone pays for a large part of the range. What makes the button different from the cutoff is not just that you steal more often; it is that when you get called, you get to realise far more of your equity, so hands that would be losers out of position turn into winners.
The button range is also where the mixed band matters most: the gap between the 43% core and the 53% wide version is 136 combos of genuinely marginal hands (Q3s–Q2s, J5s–J4s, T5s, 74s, 43s, K7o–K6o and offsuit gappers and connectors such as Q8o, J8o, T8o, 97o, 87o, 76o). Against blinds who defend and 3-bet correctly, open the core. Against blinds who overfold, the wide version is free money.
Around 43% as the core range — about 566 of the 1,326 starting combos. Against blinds who fold too much you can push toward 53% by adding the mixed band (the weakest suited queens, jacks and tens, K7o–K6o, offsuit connectors such as 98o, 87o, 76o). Against blinds who 3-bet a lot, stay at the core; the marginal hands are exactly the ones that have to fold to a 3-bet.
Yes. On the button only the small blind and big blind act behind you, no matter how many seats the table has — everyone else has already folded. The same is true for the cutoff and the small blind. The early positions (UTG, MP) are where 6-max and 9-max ranges genuinely differ.

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.
