Opinions differ - I don't like opening more than about 12% UTG in 6m, and I prefer a couple sc's to the small pp's. I open about half those Axs, randomly selected.

With the UTG range, everyone opens the same 8%. Anything else is mainly there to benefit from the respect those top hands earn us. If we get too wide in EP, our entire range is extremely difficult to play because other players can attack us using position.
