I don't want to punish anybody, I do however want to allow the user to do as he
pleases without hearing me complain.

At the point of release we relinquish all control of the engine.
Expect the settings to be altered, expect the engine to play in all sort of
weird environments.

Don't complain about it saying that's not how it meant to be played.
If you won't acknowledge that the user is boss at his end then don't release the
engine to him.

There are problems with determanistic behavior of the engines.

Done often.

Why not, it might help you locate weaknesses.

That's certainly an interesting configuration.
Does that mean all other configurations are worthless? No!

If you make it impossible I think Crafty will be kicked out of a lot of
tournaments.
People want to control the engine, if they can't the engine becomes less
valuable to them.
