Toledo chess program

[veekoo]

Linux X86 only:

I took the code at https://nanochess.org/chess1.html screen and added

Code: Select all

#include <stdio.h>
#include <stdlib.h>

Then compiled it with GCC and run it

Code: Select all

./toledos a b c

Computer plays back and it uses 7-ply. Thinking time is about 4 secs. It is said that it's tougher to beat.

Code: Select all

./toledos a

Computer plays back and it uses 5-ply. Immediate response.

I have also tried mscp chess program in Linux X86. With it's opening book it is default playing 4-ply. It's fun to watch when you enter

Code: Select all

mscp>both

then computer plays white and black against each other. More plies can be entered for example

Code: Select all

mscp>sd 5

it uses 5-ply.

This means the compiler works but that the execution is really slow.
Now trying the same code on www.gigatron128k.com, running overnight...

Toledo has answered e2e4 after only a few hours.

It also work inside http://www.gigatron128k.com, but the problem was that the emulation is suspended when the browser tab is not in the foreground (e.g. when another tab is selected, or even when the screen saver is triggered!).
