I agree. This isn't physically impossible :-)

Ok, then why not use the Fisher-System and add 3 seconds per move?

Yeah, I saw cases, where Rebel had 0-Time lost after 20 moves out
of the book, and this cannot be.
Other programs i noted, used a second per move.

ooooooops, You will tell me, such programs exist after so much
experience and time?

I think, if all programs are implemented well and the 3-seconds-per-move
add-on is used, the time-difference will be really small.


To use an extra-machine (can FICS this do?) sounds for me, to shoot
with cannons for sparrows.



BTW: Of course I know the xboard, I use crafty with xboard under LINUX !

Use UNIX or die    :-)

Where is the comet-version for LINUX ?  ;-)
