I have just tried secondchessW32 in Arena & was shocked after 1.e4 it didn't play ...d5 but Nc6!
I was so shocked I lost the game! :-)

I am glad progress has been made on search/perft and movegen.As a beginner C coder there is lots here I do not understand still!
I would like to look at the code more (when I can get time!) and try and understand it!
Thanks for your work on it Emilio and I hope you may patiently help me understand secondchess c code in time!
Best wishes

Probably in the last update I modified the piece square tables or the maximum depth: that's the only two sources I can think of that can make change its output. I suggest you to modify the piece square tables and see how the engine's play is different.

If you have any problem understanding secondchess' code don't hesitate to ask: actually its goal is to be a tool for people who want to understand how a chess engine works.

Besides, in the last months I haven't modified secondchess because at least its content is what I wanted it to be. I'm developing a new engine based on secondchess, kitteneitor, in which I try to apply more complex features.

Best regards

Just a little update; I added to the repository a png with the relations between the functions. It's quite a mess, but maybe it can help to whoever tries to understand the code.

Hi Emilio
I have done a video for my last game versus secondchessW32 on my chess youtube at http://www.youtube.com/watch?v=1X2Jqmwo8jY&feature=plcp

(I see you have recently updated both secondchess & secondchessW32 since I last downloaded the files-I look forward to checking these out when I can).

To Richard_1977
Thanks for your diagram...helps understanding secondchess function relations :-)

It's nice to see people having fun with secondchess :)

The introduction you do in the video is quite clear, and by the way, good game!

Regards

Doesn't work under Fritz-GUI, is it a winboard engine? does it mean I have to use WB2UCI adapter?

Hi Ahmed

Thanks for trying Secondchess. Unfortunatly I do most of my develop job under linux and I don't have any experience trying to run it on frizt GUI.

I guess that people who've tryed it under Windows have been able to play against it under Arena GUI.

On the other hand, if your interest is to study and modify its code (which actually is Secondchess' aim), you always can execute your compilations from an ms-dos terminal.
