10x rule as normally used sucks. bad. for lots of reasons.

I normally open TT+ all positions. In MP I'll often open all the pairs, but certainly all the mid and high ones.

Ill open a lot of stuff from LP, with hands like the stronger suited connectors being strongly preferable to a hand like KJo or some other rubbish.

I play very tight, but I don't really have many hard and fast preflop guidelines. I'm also trying to work out the open-limping part of my game on tables that aren't generally loose/passive/fishy.

Just my $0.02...

edit: opening all the pairs from LP seems blatantly obvious to me so I just left that out...
