Ed Miller's ShortHanded Article

[Dave H.]

I understood that I need to defend the big blind position more in shorthanded games, but after reading and rereading, I just don't grasp the reason behind it. Why is my equity better in a shorthanded game when a single person raises and everyone folds than it is when a single person raises and everyone folds in a ten handed game?

I have this awful feeling that I just asked a stupid question, but OH WELL!

Could someone explain please??
