New engine: belofte

[Guenther]

That's the old 0.2.8 compile with a 2017 file modified date.

Ah, thanks Tony, then I take your compile.
Yet it is a bit unfortunate that I get 0.28 from a subfolder of 0.90.

The binaries in the dist directories are sometimes older versions. You should compile the source code. If you take the linux binary in the repository, it says version 0.9.0.

I understand the problem and will reorganise the binaries in order to include the version number.

I also suggest you take the master branch. It is now up to version 0.9.1.

[Guenther]

I made a quick Windows compile using Cygwin, and this is my first test game with Belofte 0.9.0, against good old Chad's Chess.

It was not shy to promote, but decided to underpromote to a bishop. I played a second game, and it also chose to underpromote to a bishop in that game as well, so that is something that needs to be looked at.

I uploaded my compile here, in case anyone wants to play with Belofte 0.9.0:

I guess this was played with an opening book/start position?
(opening moves look too good for both programs)

BTW Belofte also missed several mates in 1 at the end already before
the funny underpromotion.

Dear Guenther,

Thanks for the test and the compile. I included your binary in the master branch.
The problem of not seeing a mate in one should be resolved in version 0.9.1.

To all,

I reorganised the binaries to include the version number in the name. Sourceforge is up to date for both Version 0.9.0 branch and master branch. Linux 64 bit binaries have been added as well as version 0.9.0 for windows. I still need to add the other platforms, so please compile for those platforms.

Hi Yves, the compile and the test game was done by Tony, I just commented on the mate problem.

[ydebilloez]

Tonys compile is fine. Thanks Tony.
I added it to sourceforge and it has now become the 'official' release for version 0.9.0. (Renamed it to lower case.)

All different older versions are now available for Windows/Mac/Linux/Solaris/... in the dist folder in source control.

Belofte will take an opening book if available under the name belofte-0.x.y.book. If no book can be loaded, it will play without book. See the manual on how to create a book.

Attention, you can configure e.g. arena to take its own opening book.

Salut Yves,

Indeed, version 0.2.8 with black seem to refuse promotion...

Corrected. Following downloads are now redirected to sourceforge.
Win 32 bit, Mac OS x86 64 bit, Linux 64 bit.

Solaris and HP UX are repackaged as tar.gz.

Unfortunately, some older binary versions are not available at this moment such as Mac OS X PPC version or Universal 32/64 bit. I will make them available through the repository after retesting them. In the mean time, please compile those binary versions from the source code.

With this, testers wanted for missing platforms.

[CMCanavessi]

I see that the engine is already at 0.9.3 in sourceforge, can anyone make a windows binary?
