Another limping question

[RcrdBoy]

rachelwxm's poll/post about when you will limp late brings up another issue I've been wondering about for a while.

How often do you let people limp on your BB? In the other thread Tosh said he open limps from the SB and bets the flop. I see this work a lot and it works against me all the time.

In general, how often are you raising your BB if CO, button or SB limp? Unless I've got a pretty good hand (AK-AT,66-AA,KQ, maybe KJs) or are really short stacked I'm letting people limp on my BB at will and feel like I'm getting bet off the pot if I don't hit.

BTW - I'm talking level 4 and up for the most part.

Any thoughts?
