Topple

[konsolas]

So I've finally finished implementing UCI and I've created the first release of my engine on GitHub:
https://github.com/konsolas/ToppleChess ... tag/v0.0.3

Windows binary (mingw-w64), but it's a cmake project so it should be easy to compile on other operating systems.

Any feedback and suggestions would be greatly appreciated

Thanks for the release. I have a couple of questions though.
Would it be possible to compile a non popcount version, which runs on older 64-bit systems?

What country should be listed with your program Vincent?

Hello Vincent,

it seems that Topple current win64 engine looses sometimes on time before the fortieth ply will be executed on WinBoard 4.8.0 GUI

During implementation of both programs ("UCI-compatibility") into WinBoard Interface I used the option -debug, but I cannot see a special saved debug file of WinBoard 4.8.0 (like Arena and ChessGUI does). Why?

'During implementation of both programs ("UCI-compatibility") into WinBoard Interface'...

No idea what you mean with the above sentence, probably you wanted to say installation instead of 'implementation'?

The debug option is set in the start dialogue (or as a flag in a batch file), but not as an engine option.
(BTW 4.80 is very old)

You can also set debugMode=true in the wb.ini but it is not persistent I believe.

Hi,

I've posted a new release which provides a binary without POPCNT for older systems, and also improves the time management in repeating time controls.

You can download it here: https://github.com/konsolas/ToppleChess ... tag/v0.0.4

[Dann Corbit]

I must say that I really like your current code base.
When I see code that well written, I see success in your future.

Thanks for this one!

I don't have the resources to test Topple against a lot of other engines, so I don't really have a elo estimate, unfortunately.
