Hi all,

I just released belofte 2.1 on linux/windows 32/64. Mac, Android and Raspberry binaries (hopefully) in next few days.
Grab its code or binaries from https://sourceforge.net/projects/belofte/

This version should be feature complete. A huge number of changes since version 2.0.8. Supported in this version: Winboard 2/CECP protocol. UCI protocol. All chess rules (50-moves, minor promotion, 3 times position, e.p.). This is a complete rewrite from scratch from version 0.x.
It performs better than the old 0.9.12 version in bullet and closes in in CRCL 40/2 to the old version, even without much chess logic yet. Estimated 1000 Elo.

Tournament results at 5 seconds per move: (cutechess st=5)

Code: Select all

I don't have a Mac (and probably never will), so I can't create them. (I could try cross-compiling, but then I'd be compiling and releasing binaries blindly, and I don't really like that.)
Im getting a Mac Mini m1 soon and plan to help supply mac builds for the community (at least m1 builds).

Thanks Yves. I'll keep it in mind to test it as soon as I can.

I just released belofte 2.1...
I ran a quick test of 100 games at 1m+0.6s against Rustic Alpha 1.
Score of Rustic Alpha 1 vs Belofte 2.1.0: 100 - 0 - 0 [1.000]
... Rustic Alpha 1 playing White: 50 - 0 - 0 [1.000] 50
... Rustic Alpha 1 playing Black: 50 - 0 - 0 [1.000] 50
... White vs Black: 50 - 50 - 0 [0.500] 100
Elo difference: inf +/- nan, LOS: 100.0 %, DrawRatio: 0.0 %
100 of 100 games finished.
Some things I noticed yesterday are:
* Rustic threatens mate in 1 or 2, but this can still be prevented; but your engine often doesn't and just plays something unrelated.
* Rustic uses a piece or pawn to attack a piece of higher value, and Belofte doesn't react to this.
* Belofte sometimes captures a lower-valued piece with a higher-valued piece, even though it can immediately be recaptured. (No QSearch?)
* Belofte seems to have a great eagerness to capture on f7, even though that doesn't achieve anything most of the time.
* The engine sometimes makes strange moves, such as moving a defender in such a way that a piece is now unprotected (and hanging).
Author of Rustic, an engine written in Rust.

I noticed a segmentation fault running the Mac version upon program exit. The mac version runs fine but it needs to be fixed. Any help welcome.

Android (thanks Archimedes) binaries have been published. Mac intel as well. Still lacking Raspberry and Apple silicon, amongst others.
I also hope to improve playing level and style in next releases. A lot of work remaining here.

I tried building in Visual Studio Community but gave 359 error messages. Granted I'm new to VS so will keep trying. Anxious to try this out.
