Depends. Against grandma? Against 5 computer progs? Or against 420 different
masters and GM? -  Tony, before you get excited too early let me confirm you
that the SSDF games, maybe 800 of a new program version against 8 +/- 2
opponents is NOT sufficient so far. So I'm sorry, your invoice was rejected by
the Grand Jury. And sorry, games against Mephisto II and Complete Chess System
cannot be accepted because of different species.

P.S. Matador started with 2400 in Paderborn, which is a bit of a joke.
Unfortunately nobody seems to know what 2400 really means. <sigh>

Tony, if you in SSDF would lower your overall level from 2700 to 2300 I could
see some hope. But this should be started as late as March the first, and
without conditional delay. Otherwise my reports will be negative next month.

Time has run out for you!
