Damn, that is clearly a regression caused by this commit: https://github.com/cutechess/cutechess/ ... 2306127f7f

Maybe I should remove the variant check completely and only return an error if the starting FEN and/or the opening moves aren't compatible with the variant. I'll write a fix later today.

Be aware of crazyhouse epd.

Winboard:

Code: Select all

The on-hand pieces are in

[PPNNNBrq]
The promoted pawn to queen is

found in c8 square. This is the same as in Lichess server.

Lichess server:

could be mistaken as new rank.

But perhaps just use the winboard format where Sjaak, TJChess and Imortal have supported.

Support for uci engines that plays a variant.

Atomkraft is an engine that can play atomic variant. It is based on stockfish 2.1.1 which can be found in,
https://github.com/golmman/atomkraft

Jim windows compilation:
http://www.chess2u.com/t9565-atomkraft

I am developing an atomic xboard engine and would like to have atomkraft as sparring partner.

It would be nice if you can support this uci engine.

From uci command.

Code: Select all

...
option name UCI_Chess960 type check default false
...
But this engine would play atomic by default.

UCI_Atomic option could be used to inform cutechess that the game will be played under that variant for uci engines.

Cutechess supports Crazyhouse FENs like this:

Code: Select all

rnbqkbnr/pppp2pp/8/4p3/8/6P1/PPPPPP1P/RNBQKB1R w Pn KQkq - 0 4
It was such a long time ago when I implemented crazyhouse so I don't know how I came up with that. But I'll support whatever Winboard supports in the future.

Thanks, and it is good to know the zh fen recognized by cutechess, would stay away from zh opening epd use then at this time.

CuteChess already has this code in uciengine.cpp:

Code: Select all

static QString variantFromUci(const QString& str)
{
	if &#40;str.size&#40;) < 5 || !str.startsWith&#40;"UCI_"))
		return QString&#40;);

	QString variant;

	if &#40;str == "UCI_Chess960")
		variant = "fischerandom";
	else
		variant = str.mid&#40;4&#41;.toLower&#40;);

	if (!Chess&#58;&#58;BoardFactory&#58;&#58;variants&#40;).contains&#40;variant&#41;)
		return QString&#40;);
	return variant;
&#125;
So UCI_Atomic should work.

Cutechess-cli is now at version 0.8.2: https://github.com/cutechess/cutechess/ ... /cli-0.8.2

This is a good update for those users that play non-standard variants like Crazyhouse.

Thanks it actually works even without UCI_Atomic.
