Scorpio chess engine by Daniel Shawul

[Dann Corbit]

It is a nice sample engine to understand the basics:

Dann (and Dan),

Thanks for this executable. I didn't look at the code, but it looks like the perft values are slightly off, e.g.,

perft 3 = 8909

which is neither leaf (8902) nor total (9322).

It appears to play fine, though, which interestingly makes chess engines seem less brittle than some other kinds of software.

Hi Micheal
Yes,I know perft values are not displayed correctly.
That is because some moves are generated twice by the incremental move generator. If you comment out the incremental move generator code in moves.cpp , it will display correct numbers.

Thanks for the explanation, Daniel.

I should have suspected you already knew about it... After all, why have a perft function if not to use it for debugging?!

Hi Dann:
There are two executable. Which is the difference between them?
Nothing to do with Scorpio but try to remember to fix Hoichess,
Best regards,

The two binaries are built by different compilers.
The MSVC binary is a little faster on my machine.

Thanks Jim!!
one of the benefits of not naming your enigine "...Chess" gets
you beautiful logos. Those that end with chess usually have a chess
board on their logo.
