KQs against an unknown raiser. Preflop question

[martybonus]

interesting reading this one.
I'm rather surprised at so many recommendations to fold, but it does make sense. Especailly cos as someone said, 'there's another better hand coming shortly' or something like that.

If this weren't raised already, I'm assuming Hero would either limp or raise (maybe not?) pre-flop. I know the SSHE advice is to play *extra* tight if it's been raised in front of you, but it also says that if you've limped in, you should generally pay the extra bet if someone raises after you limp.

by somewhat stretched logic, doesn't the same sorta (but not exactly) apply here? if hero was going to pay to limp in for one bet anyway, why not cold-call? after all, SSHE says it's okay to cold-call every now and again.

i realise there's a big diff between money you *would have* put in the pot and money you *did* put in the pot.

but maybe we can assign a 'value' to each hand PF...AKs is usually worth 3bets or a cap, AA is obviously a cap, and KQ is, say, worth 2 bets preflop, is it worth a cold-call here?

dunno, like i said, this logic is a bit shaky. but it just seemed a bit passive to fold KQs to a raise when it might actually be worth a raise itself...

or maybe i'm overestimating how good a hand KQs is.
