Durandal

[chrjly]

Hello everybody!

Durandal is a very simple (and very weak) UCI chess engine written in Pascal, and able to play traditional chess, Fischer random chess, Capablanca chess, Capablanca random chess and Gothic chess.

Source code, Windows and Linux binaries are here:

I wrote my first chess program in Pascal, compiled with the UCSD Pascal compiler on an Apple 2 computer. A long time ago.
Its speed was a few hundreds of nodes/sec. It was weak too.

Thank you Christophe for your message. Yes, the name of the engine comes from that.

By the way, while I made the version 0.1.1, I didn't think to the Capablanca variant.

Code: Select all

   8 Durandal 0.1.1 [random]     0  124  185    86    1%   881    2% 

I hope that the next version will be better.

Durandal has now a basic built-in GUI for playing Capablanca chess.

It's a Lazarus project.

Thanks very much, for offering this version of CapaBlanca Chess, probably by playing a more complicated version of chess it will force our brains to become more Alert and when we return to standard Chess, we can solve more tactical positions faster than before. Capablanca after being undefeated for a long time thought that Standard chess was too boring for him, but of course not for the rest of his competitors

Note: Now that you developed a basic GUI for Capablanca Chess, how many Chess engines besides Durandal can play this version of Chess, and can you make a self extractable version like Arena GUI ?

You can see in my previous post a list of engines playing Capablanca chess.

There are also:

• Fairy-Stockfish
• Heretic
• SMIRF

and maybe other that I don't know.

By the way, I made Linux and Windows binaries of Durandal GUI.
