Actually, position is the biggest factor in my own strategy. Let's see - I steal more frequently from the BTN and SB, and my range gets stronger in MP and EP. Regs know I steal frequently from the BTN and SB, so they're more likely to 3bet me or call when I open from those positions. Since I'm more likely to "lose" the bet I'm opening with, I open smaller in these positions than I do from MP and EP.
It's important, though, that I don't change the size of my BTN open raise based on the strength of my hand. That way, when I open from there, they can't really be sure whether I'm opening 76s or AA - obviously I'm delighted to get 3bet when I'm holding AA and less happy when I'm holding 76s.
I also look at who hasn't acted yet when determining my open raise size. Someone who calls alot when I open raise, and then folds to a flop cbet, deserves a bigger open raise - I'll get more money from them over the long run. Someone who's really tight and doesn't call much deserves a smaller open raise, since there's little risk they're going to play back at me.
There are some very good discussions of this on this forum - unfortunately, I don't remember exactly where, maybe someone could suggest? I think this was fp, chuckts, belgo, or zach, don't remember exactly?
