I don't believe that.  Exactly _which_ 100+ computer chess tournaments did
he direct???

I didn't even see him claim that.  I believe he said he had directed over
100 tournaments, including some computer chess events.  And I really don't
believe that last inclusion, because he seems so unaware of normal rules used
in computer chess events...

How can it be any tighter than it is right now?  Read rule 5 and rule 6
carefully.  They specifically define what the operator can do.  And doing
something other than what the program says is _not_ included in that list.
In fact, rule 5 covers the remedy when an error is made by the operator,
and doesn't even discuss the possibility of the operator actually intentionally
doing something different, because that has _never_ been allowed.

That's fine.  It was simply the wrong decision.  The operator made a mistake
by not claiming the draw when the program claimed it.  Rule 5 is clear and
requires no interpretation at all as to what must be done when an operator
mistake happens.  The ICGA then tried to justify the decision with lots of
circuitous reasoning, completely ignoring rules 5 and 6.

So if a player moves his King to b1, and his rook to c1, and calls that
castle-queen-side, I, as the TD could say "sure, that is ok, I choose to
overrule the normal rules of chess and let that new form of O-O-O stand?"

I don't see where _any_ group has the authority to override written rules.
They can interpret them if they are vague or ambiguous, or if a circumstance
comes up that doesn't directly fit an existing rule.  But they can't just
say "this rule is not going to apply here..."

Where do you conclude that they have that right?  IE what written instrument
gives them the ability to overturn a decision made by all the participants
at the start of the event, where the rules are discussed and explained?
