I play about 25/13 ish. I tend to raise all PP from anywhere not on the blinds (although I may start experimenting with just limping them, as advised by ISF). Raise all suited connecters + gappers starting at 9 10 UTG down to 5 6 on the Button. In early position I have stopped playing A 10, K 10, K J, Q J os and other such hands that don't play so well OOP. Also I raise most suited aces depending on table conditions. On the button depends on the blinds, if they are tight any two once every few orbits, but generally a bare ace is enough. I only really limp in the SB.

However I've only been playing for about 7 months, so this is still not by any means perfect I would be interested if anyway had other suggestions.
