I think it would be great if it were more widely adopted; perhaps there is a good opportunity for that here.
I remember you posted before about handling variants in uci.

There's no getting rid of UCI_Chess960, and it serves some purpose in letting the engine know it plays a shuffle game/should expect and use KxR castling notation, but beyond that halting this type of fake option proliferation is a good thing.

Re: Cute Chess 0.9.4 released
Exactly. UCI_Chess960 is not so much a variant selector as a protocol modifier, and could be used orthogonally to any variant setting to switch the protocol to a Fischer-castling-proof mode. (Of course even this is redundant as a setting, and could have been understood automatically from the position fen. But at least it announces to the GUI that the engine understands Fischer castling,and associated move and position notation.)

Re: Cute Chess 0.9.4 released
Cute Chess handles both "UCI_VariantName" (check) and "UCI_Variant" (combo) UCI options, but none of those settings are shown to the user.Ferdy wrote:Yes you cannot see it because what I really mean is UCI_<variant name>.

Re: Cute Chess 0.9.4 released
I was just informed by the Stockfish-variant team that they will support the UCI_Variant combo option. Most likely in addition to the check options, as they are compatible with each other: If no check option is set, the combo option decides, and the default value of the latter is normal Chess.
My recommendation to GUI developers is to ignore the check options when the UCI_Variant option does exist.

PyChess supports UCI_Variant from the time Evert suggested it, but not supports individual UCI_* options with the exception of UCI_Chess960.hgm wrote:I was just informed by the Stockfish-variant team that they will support the UCI_Variant combo option.

Re: Cute Chess 0.9.4 released
A wise choice. I will support it in UCI2WB too. Now we should only hope that all engines implemeting a certain variant will use the same name for selecting it...
