That is what I thought at the beginning, but when you read it in the context it
makes a little bit of sense. It is an etiquette rule whose spirit is not to take
advantage of inherent disadvatages of the the machines and humans. The human
should not be dragged into an endgame that last too many moves when it is a draw
and the machine will not lose on time because of the operator.

In the only case that it could be unfair is in some KQPKQ positions, I guess.
The rest of the tablebases draws should be pretty simple for Kasparov to defend
without being tired, but it will take them 4 hours to complete if the machine
decides to go on and on.

It do not think the rules is perfect, but it is not disgraceful. There may be
other better options or better implementations.
