Easy Way To Calculate Blind Defense?

[Wolffink]

Hi, I've heard that you can defend your small blind in 08 by not calling with a hand that you wouldn't call with on the button. Okay, that's easy.

But is there a quick rule-of-thumb to do the same with your Big Blind when facing a raise?

Assume a loose 08, typical of lower limits, with 4-5 players on most flops.

I've heard that no hand is much more than a 60% - 40% underdawg, but I think that's assuming heads up. I think I've been overcalling on my Blind defense, only to have to fold unless the flop hits me really hard. I have a feeling I really have to tighten up on my Blind defense--perhaps playing a hand 2-4-Q-Q, if they're single-suited as minimal requirements.

I've seen Cappelliti's point system for Big Blind defense, but he assumes it's Head to Head. This is totally different than the situation I often face with a herd of players some of whom probably have A-2, A-3, 2-3, or 4 high cards.
