If he is trying to be funny my advice would be to not repeat the same joke 10
times.

Of course, trench digging is an international sport :)

Lot's of reasons it doesn't work in practice though.

In principle it might work, if one could design a huge set of incredibly
balanced positions, ie containing both best move and avoid move cases.

The question of balance is really important.
Ie. too aggressive is just as bad as too passive, and since many suites only
test for aggression there's no way to know if those engines have the right
balance.

More fundamentally though, how will you ever _prove_ that you have created a
suite with the right balance?

Come on now, you germans should set the bar a little higher than that, at least.

I haven't read CSS much, for obvious reasons, but if Dieter is the only one
trying to hold down the fort in there, then I'd not be surprised if a lot of
nonsense survives unrefuted.
