difference bet raising first in vs w/ prev callers

[rowhousepd]

How do people feel about how/whether your range changes when you're raising first in vs. raising w/ previous callers?

Let's assume I'm in late position at a standard weak microstakes cash game w/ no particular reads on anyone at the table. In the CO, for instance, I'm open raising ~25-30% of the time and always w/ pairs, broadway, Axs. So does this narrow or expand if there's a MP limper? Is it the same? What if I have 2 limpers? I know the amount I raise by will change (generally 3xbb +1 per limper), but am I always going to punish limpers w/ the same hands I would play if it were folded to me?

(Btw, my point here isn't whether the exact particular opening PFR range is correct to begin with; I'm just trying to get a sense of whether it changes much depending on limpers.)

Basically, if you're happy to play against fish in position post flop, then raise your usual range, the limper is putting more dead money into the pot and usually plays badly out of position post flop. If you think this will get you into trouble, work on your post flop game, and in the meantime limp behind with yours pps, suited broadway and Axs, raise your premiums for value, and fold the marginal hands like Axo 78s KJo etc that you might have raised had noone limped.
