Apparent contradiction to a newbie

[kld]

I have spent some time following recommeded links and am a bit confused concerning playable high cards in O/8.

The confusion comes from reading Russ G. (Poker Mafia) and the Hutchinson point system.

Hutchinson clearly states that a playable high hand should have all 4 cards ten or above with a pair.

Russ G. says that they should be 9 or above and have no
pairs.

Can someone enlighten me?

Thanks,
Ken
