I'm testing it with Fritz 7b on a 1.2 GHz Athlon.  It took about 11.5 minutes
for it to choose ...Bxg3 as best, and 29 minutes to get a score better than 0.00
(it's at 0.22 for Black so far).

If it really does win in all variations, ...Bxg3 may be the strongest one ever
played in a real game by a piece of software you can buy on sale at your local
store for US$20!
