At 6Max NL I'll open every PP for a standard 3-4xBB raise regardless of position. At FR, I'll open PP 77+ from EP. All others I either limp or fold. But I hate open limping from EP because it screams small PP.

With low PP 22-66 (and sometimes 77-QQ) the villain must have around 15-20x the amount to call the bet left in his stack. Same goes for SCs since the odds of flopping a set and a flush/OESD are about the same. And of course we'd rather have position on the raiser.

Therefore, to go "set-hunting", we would prefer to have as many full stacks as possible at our table, us included. I always get a kick out of these guys that buy in for 20-30BB and proceed to go 4/2 over a 100 hands looking to catch that set or shove AI with AA/KK.

I also get a huge laugh when I see players at LHE playing PP's as if it were NLHE, not realizing the implied odds aren't there. Well, that and buying in for less than 12BB, but that's for an entirely different topic.
