I see ttanka posted his revised grouping. Comments about ranking hands aside, I still think it's too limit centric.

Group 0: AA KK
Yup

Group 1: QQ JJ AKs
I value QQ a lot more than JJ which I place closer to TT, but that's probably more of a personal thing...

Group 2: TT AK AQs AJs KQs
AKo is way better than TT and the big suited cards since you can protect it better in no-limit.

Group 3: AQ 99 ATs KJs QJs KTs

Group 4: 88 AJ KQ QTs A9s JTs AT A8s
Are A9s and A8s really that good? Both have kicker trouble and they can't make a straight.

Group 5: KJ 77 QJ KT QT JT A7s K9s Q9s T9s J9s
QJ KT QT JT are all trouble hands unsuited.

Group 6: 66 55 44 33 22 A5s A6s A4s A3s A2s
Baby pocket pairs deserve more respect than this. No limit gives them the implied odds to make them major power-houses with small blinds relative to stack sizes.

Group 7: A9 K9 98s 87s 76s Kxs(?) T8s(?) 97s(?) 86s(?) 54s(?)
A9 and K9 are just plain off my play list. No flush, no straight for A9 and K9 makes an unlikely sucker straight.


Here is a suggested ranking for an 8-10 player table:

Group 0: AA KK
Group 1: QQ AKs AK
Group 2: JJ TT AQs AQ AJs KQs
Group 3: AJ KQ 99 88
Group 4: 77 66 55 44 33 22
Group 5: ATs KJs QJs KTs QTs JTs
Group 6: Axs tight suited connectors (T9s - 43s)
Group 7: Kxs semi-tight suited connectors (J9s - 64s)

On a tight table drop KQ and AJ, tread carefully with AQ out of position. Play group 6 and 7 hands from more positions.

On a loose/wild table play group 5, 6 and 7 hands only in position.
