but what do you suggest to do if both program are not stupid to make a bad move
but continuie to play.

The game can continue 1,000,000 moves and it can take 100,000 hours(assuming
that every side use 2 hours per every 40 moves.

100,000 hours are more than 10 years.

Do you want the ssdf testers to wait more than 10 years to finish the game?

I think that they have better things to do.
