From middle position at a 9-handed table you open about 16% of hands (206 combos): 44+, A8s+ with A5s–A4s, KTs+, QTs+, J9s+, T9s, 98s, ATo+ and KJo+. Six players still act behind you.

The range: 44+, A8s+, A5s-A4s, KTs+, QTs+, J9s+, T9s, 98s, ATo+, KJo+
15.5% of hands (206 combos)
Middle position in full ring is UTG with a little breathing room. The two extra folds in front of you remove the two tightest ranges from the pot, which takes the opening range from 12% to 16% — pairs down to 44, suited aces down to A8s (plus A4s), QTs, J9s, 98s and the offsuit ATo, KJo all become profitable.
The hands that get added are mostly suited, and that is the pattern to internalise for every early seat: what makes a hand playable from up front is not raw high-card strength, it is the ability to make a hand that can stand a lot of pressure. 98s makes straights and flushes; K9o makes second-best top pair. Only one of them belongs in an early-position range.
The single biggest full-ring leak is opening the 6-max middle-position range (the 6-max hijack is ~21%) from 9-max MP. Those extra three players behind are worth real money, and the hands you would add — K9s, Q9s, offsuit broadways — are precisely the hands that get dominated when someone behind wakes up.
About 16% — roughly 206 of the 1,326 starting combos: 44+, A8s and better plus A5s–A4s, KTs+, QTs+, J9s+, T9s, 98s, ATo+ and KJo+. That is wider than 9-max UTG (12%), about the same as 6-max UTG (16%), and well short of the 6-max hijack (21%).
Both make straights and flushes, but 98s does it with better high-card back-up: when it flops top pair it is a nine, not a seven, and its straight draws are more often to the high end. With six players still behind you, that difference is enough to move 98s over the profitability line and leave 76s below it.

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.
