The most important change in this release is Syzygy tablebases support.

Should be ~40-60 ELO stronger than Combusken 1.0.0.
This version is not working in my android 10 device (realme 5pro) and the previous version working well.
Do something please!

I'm sorry for inconvenience. I thought that build compiled for Raspberry PI would be sufficient, but it is not the case.

I've added additional combusken-android-64 file, however unfortunately this build lacks syzygy support(syzygy-related uci commands are no-ops).

I don't get that code

Code: Select all

                kingDistance := Min(int(distanceBetween[fromId][whiteKingLocation]), int(distanceBetween[fromId][blackKingLocation]))
		if kingDistance >= 4 {
			score += distantKnight[kingDistance-4]
		}
distantKnight seems to be applied whereever the knights are

I think "fromId" is the knight's location.

I've managed to compile Combusken on my phone, and version that supports syzygy is now on github.

I see some of your patches for 1.1 where inspired by my work for Ethereal, like the stacked passers code or the distant knights penalty. Nice ! I'm happy the ideas helped.

I hope you can keep on gaining elo, and find some original elo-gaining tricks of your own that could help other engines too. :)
Thank you! I hope that true.
