To reach the desired goal, it's not required to change the rule IMO. It would be
sufficient *not to claim* the 50-draw. It's a "can" rule, not a must, so to
speak... Of course, both opponenents (or all participants in a computerchess
event) would have to agree not to claim 50-draws so that it can make sense to do
so. I think we can expect enough common sense to draw games which really can't
be won, by agreement nevertheless.

It would be not so easy to use EGTBs to help with the decision though, because
-and as it has been researched and reported by Helmut C.) - different table
format my report different results (DTM,DTC,DTZ,DTZ50). At least I think that
may be confusing. I'm not sure.

(But the progs would probably have to be modified anyway.)

Basically I'd prefer to find solutions within the FIDE rules rather than to make
specific rules for computerchess. In the 50 moves case, it seems possible to me
as it is not a forced draw according to FIDE, but depends on a player decision
to claim or not to claim.

Programmers must not forget: Chess programs are not for engimematches only. :-)
The "human user" might insist that it acts FIDE-compliant all the time.

(The focus is often too much on some high-ranking comp tournaments... what
happens there isn't so important. It's by far more important what the software
on the user's computers at home will do or can do.)
