playBunny: It did occur to me after my initial post that debating might also be a form of relaxation, like martial arts to some folks. What disquieted me was that there seemed to be quite a bit of acrimony involved in the debate, but I may have read more into it than was there.
On a totally different point, I am very interested to see what happens when Fencer re-runs the BKRs tomorrow. I am betting there will be huge changes, not just slight ones. I have noticed the difference already, and I doubt I'll ever see 2700 again! It wouldn't surprise me if we had a different #1 player after tomorrow.
