Re: [Scidvspc-users] patch for chess960!

[Steve A <ste...@gm...>]

Haha, after a little look, it looks ok :). Thanks. I think maybe your
backend changes are more robust than that of Bens' chess960 patch.

I have opened a ticket for it.
    https://sourceforge.net/p/scidvspc/tickets/4/
I thought Sourceforge had a patches page.. but i cant find it, so maybe
they have gone.

Otherwise, sorry, but i don't have much time, and the C backend is not my
forte.
You look like you know what you're doing more than me here.
If it's just general TCL help you're after, just shoot me an email.

A starting point for modifying the tcl is to notify chess engines about 960,
which works with Stockfish.

Ben Hague's chess960 patch is in the src/patches directory, and includes
some tcl changes.

I can probably look at that sometime. Any other things that come to mind ?

That'd be great. fics.tcl a bit of a monster, but i've tried to document it.

One other thing comes immediately to mind.. It'd be nice to handle/convert
the X_FEN castling conventions.

Hmmm - I have found a decent bug regarding vars and game saves. I'll post
it to the ticket page.

cheers, Steven
