(b) The FIDE rules were cited enough to make it clear that FIDE rules were the primary set of rules with modifications as appropriate to accommodate the silicon nature of the contestants. Chess computer tournaments have been going on for several years so the rule set should be reasonably clean by now, with the possibility of minor needed improvements. (c) Perfect rules are useless if not followed. (d) Wise tournament organizers are needed to rule on unexpected situations where the rules prove to be unclear or obviously wrong. Until the rule set is ABSOLUTELY perfect, a wise tournament director will be needed. The fact is that chess software is still evolving and this necessitates a corresponding evolution in the rule set as well. Bob D.
