Having position is great, but on the other hand, if you're on the button and the raise comes from a couple of spots off the button, they're much more likely to have a hand than if you're in the blinds and the raise comes from the button.

I think you really have to open up your range of re-raising hands in the blinds if you have a loose raiser to your right. If a guy is raising on the button with 20% of his hands, just calling him with JJ or TT is terrible. I love sitting to the right of a nit in a 6-max game who won't re-pop me without a monster hand.
