1/2 the time your opponent has a bottom 50% hand. A raise will win the blinds. often.
1/2 the time you will have a top 50% hand and should be willing to play for a raise.

when your hand is in the 30%-50% range, a raise will push your opponent out 50% of the time ( his bottom 50% hands), when he does play , he will miss the flop 70% of the time and you will hit it 30% of the time.
gawd that is a complicated sentence.
I play all but the bottom 10%
the bottom 10%-20% is read dependant
I guess I treat it just a bit tighter than heads up. Maybe it should be treated just the same. Except that with 7 hands folded you know there aren't any top 10% hands out there ...yet.
sorry if this reads connfusingly, someone made f'nn decaf this mornning...
