What do you guys do at tables where the raises are usually weak (like 2-3xBB open raises or they only raise 2-4xBB even with multiple limpers before) and still garner multiple coldcallers? Do you guys still regard them as a raise and muck marginal hands like KJ, KQ if it's weak-raised before it gets to you or do you call and hope for a lucky flop to stack the weak raiser

Also, are there any adjustments to be made when playing PL versus NL? Are small PP not worth coldcalling late in hopes of flopping a set since your betting is limited to pot?

EDIT: Argh-- I thought I was posting this in Beginner's Circle. Sorry. Could a mod please move it?
