I play limit holdem......

8's and under I don't even play from early or middle position. I'll limp from late position and won't call a raise from any position. 9's and 10's I'll limp from middle or late position. 9's I'll throw away for a raise and I'll call with 10's from any position. If I miss the flop and there are overs, facing a bet I'll fold. If there are unders I reraise.
