cutechess-cli 0.8.0 released

[Ferdy]

Hi Ferdy,

I guess you shall set the suite type to epd somehow. Default suite type is pgn.

Yeah I did it here.

Code: Select all

-openings file=%startfile% order=random format=epd

I tried to run atomic variant game match using epd as opening file. There was a warning.

Code: Select all

Warning: The opening suite is incompatible with the current chess variant

The game continues from start position.

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

q1Q~N4/k2R4/ppppP1pb/3B4/3P4/3p1P2/PP4PP/R1B2RK1[PPNNNBrq] b - -

The on-hand pieces are in

Code: Select all

[PPNNNBrq]

The promoted pawn to queen is

Code: Select all

Q~

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

Lichess server:

Code: Select all

q1Q~N4/k2R4/ppppP1pb/3B4/3P4/3p1P2/PP4PP/R1B2RK1/PPNNNBrq b - -

The on-hand pieces are in

Code: Select all

/PPNNNBrq

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.

I've fixed the bug. Will update cutechess-cli release in the next few days.

Be aware of crazyhouse epd.

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.

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

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.
