Fix wrong constant usage in go mate

Fixes an oversight in https://github.com/official-stockfish/S ... /pull/5094

In theory, master could stop search when run with `go mate 247` and return a TB loss (not a mate score). Also fixes the spelling of opponenWorsening.

closes https://github.com/official-stockfish/S ... /pull/5096

No functional change

Many thanks.

It’s seems that it’s not a good and reliable version. I haven’t test it yet.

Thanks Cengiz-Baba for your tests. (Three tests )Totally super strong engines should practice more with black pieces. They are not good players with black.

[Cengiz-Baba]

You're Welcome Homoyoun.

I do this on purpose and I use UHO test suite. Because a duel with a low DrawRatio will be bloody. Engines behave very differently with games between +0.90 and +1.0 and it becomes easier to compare engines.

Best regards, Fringe.
