Why is pocket 10 way better than pocket 9?

same reason why pocket J way better than pocket 10

The bigger question is why pocket kings are way better than pocket queens. Seems sexist as hell.

for that matter where are pocket non-binaries

Utterly dismissed. Yet for some reason Aces are revered.

But sometimes pocket 2 is better than pocket 8

When 22 hits your overall range is weaker therefor it has a higher chance of getting value or facing aggresion

And the removal effect causes hands like 55 and 44 to be less valuable than 33 and 22, because SB often 3bets A5s-A4s but not A3s-A2s.
