my pfr's up around 13% after 50k hands...

i think u should never say never. it's rarely correct to open limp but sometimes the game will call for it. for example, 55 or lower pps at loose passive will call for open limping at EP. esp in games where u're constantly seeing 4-5 limpers behind you.

usually i will auto-raise any mediocre hands- including low pp, when folded to in LP.
