"So at loose tables with many limpers who are very likely to call the PFR we tighten up our raising in position to big aces and PPs? (limping SCs and lower PPs?"



Correct. You need a stronger hand to raise multiple players than a single limper or just the blinds. But you dont need to be as strong as aces-queens. On a weak 6max table where the entire table limps to me on the button I would raise AJs+ and 99+, making my pfr 4bbs+ 1 bb for each limper. You cant limp with aq six handed.

That being said, I would limp with drawing hands (sc/ low pp) and fold decent high cards such as A ten, K9 etc. Again, with unpaired high cards its either raise/fold.

Punish the limpers bro
