Jan has 18 computers, from which usually at least 12 play at the same
time.

Average game length is not so long as chessbase auto232 players
quickly abort games when they fear they lose and fail low, despite
that i had put in a 50 minutes timeout to start next game.

So then they abort game after like 25 moves, but i learn then that
this opening is cool to play 'em.

Also some manage to get chessbase to use it as slave, i had big
problems to manage that. Could only get'em to work as master.

So quickly a new game gets started then, despite 50 minutes timeout...

So quite some games are under 30 moves and unfinished (so called
aborted). Other games are longer, but of course no game is longer as
60 moves. If one of the sides get mated then of course result can
get stored and next game can start. I forgot whether chessbase auto232
player directly starts game then, idem for shredder and diep. No idea.
I guess diep needs 50 minutes time out then in the few cases it is
master.

So a game on average hardly gets above 6 hours for the fast machines.
Some slower machines like celeron500 play at 5 to 6 hours a game though,
so that takes longer there. Those produce like 3 games a day (day=24 hours).
But the fast machines, and Jan has a lot of them nowadays, they produce
quickly games. Usually i get from Jan a bunch of games after a run of
3 to 5 days. Because of the many aborted games i hardly count the total
number of games. Usually a combination produced rapid games so
those are inside the testset too, though i hardly check them out.

But with nowadays 12 machines playing and in past up to 18 machines
playing the number of games produced is *huge*.

Way more as diep plays games on FICS + ICC and most important is that
i also have the scores of the opponent and other interesting info
which you do not have from ICC/FICS.

Best regards,
Vincent
