Released Toledo Nanochess with Winboard interface
Hi everybody, I have uploaded a new version of Toledo Nanochess and it is 40% faster.
Also a version with integrated Winboard interface, the source and the optimized executables are downloadable as a pack. The source code sizes up at slightly less than 2 KB of C language. This is currently the smallest Winboard engine around.

Finally, an engine I can beat.
Nice programming by the way, although your code is a bit hard to read.

Re: Released Toledo Nanochess with Winboard interface
I must have bonked something when I was fooling around with the source code because I have never seen any engine play this crazy.

Re: Released Toledo Nanochess with Winboard interface
I compiled the source (as released) without the Winboard interface, and played from the command line. The same game is generated as the one you posted.Dann Corbit wrote:I must have bonked something when I was fooling around with the source code because I have never seen any engine play this crazy.
