KnightX 4.6a engine released

Post by chrjly2 »

This is a bug fix release. Since v4.5, the engine was considering the under-promotion as a queen promotion when it was played by the opponent.
Thanks to Gabor Szots for reporting the problem.

Thanks, Christophe, for the quick fix. I can see it's already 4.6b.

Note: Upon starting it displays 4.4 as the version number.

Yes, I have released version v4.6b.
I have Restored the pieces values to the v4.5 values. The Pesto table pieces values of v4.6 were not appropriate.
Regression tests give +110 elo.
In the next release I will update the wrong version you have seen.
