Well, Hermann 2.5 (the oldest version on Volker's website) seems to use the UCI standard; it has the UCI_Chess960 option.

The Chispa download seems to no longer exist; the links referring to it from the Chispa blog are dead.

Gothmog-frc manages to crash wine! :shock:

I could compile UCI2WB on my big machine where ACG did not delete Cygwin, though. And it seems to work: Gothmog played an FRC game against itself, in which both sides castled! 8-)

So in the next release of WinBoard it will be possible to play Arena960 engines by ticking USI/UCCI.

I can send you Chispa if you like - it isn't commercial so that isn't a problem.

Yes Hermann is Shredder UCI standard as far as I know.

Sometimes I've played dozens of games with an engine until a castling problem has then surfaced. I guess over the years I should have kept a database of positions that can trip up engines, but unfortunately I haven't.

If you have a Linux binary of Chispa, it would be nice if you could send it. Then I can test on Linux too. I will PM you my e-mail address.

I did test Hermann on Linux, and even the Shredder standard works through UCI2WB. Not that this is very important, because Polyglot would be able to handle that. But it is nice to know that it does. Only downside is that it makes use of an undocumented feature of WinBoard to make it use KxR notation, rather than converting the O-O to KxR by itself. That might prevent it from working with other GUIs than WinBoard/XBoard.

If the protocol gets it wrong, things will surely hang on the first castling that is played: there are no castlings where the notations in both standards are accidentally the same. If you see engines that have occasionally problems with castling, I am pretty sure that this then must be a proble withing the engine. (Which is not at all unlikely, because there are many special cases depending on piece placement where things can go wrong that in most cases would go right.)

Ah, thank you!

It doesn't seem like Chispa plays according to Arena960 protocol, though:

XBoard here sets the option PlayFRC to true at startup, and finally receives readyok. Then Chispa should be set for playing FRC, right? But when it receives the 'position fen' command, Chispa responds with the non-sensical message that there are no Kings (while K and k are obviously there). Then is starts to complain that the castling flags do not correspond to the Rooks. And then it turned out it ignored the entire FEN, and starts playing from the orthodox start position (Ng1-f3).

So it seems Chispa is neither UCI (no UCI_Chess960) nor Arena960...

Hmm.. I've played 2,200 games with it and I think all of those are probably through ChessGUI.

Well, so what do you have to tell ChessGUI to make it work? Obviously it is not enough to just choose between UCI and Arena960 protocol, as Gothmog and Chispa do not use the same protocol. What worked for Gothmog does not work for Chispa.

In the quite old version of ChessGUI I run, it is set up as UCI2 960_OO

Matthias changed how this is set up in later versions. If you like, I can play a game and send you the log.

It seems that in the ChessGUI variants tab there are 4 radio buttons where you can independently change the type of FEN (KQkq vs HAha) and the type of SAN (OO vs KxR). Is it that Chispa needs HAha FEN like Shredder and OO castling like Arena?

That would mean there are actually 4 protocols. And you can apparently combine this with the option UCI_Chess960 (Shredder) or PlayFRC (Chispa) or none at all (Gothmog) to activate it. That makes already 12 different protocols, where you typically would have no idea what to choose, as a noob user.

Given that this 'Arena protocol' is an illusion, it seems better to just let the user control the individual settings through separate options. XBoard already allows you to override Shredder FEN (HAha) for KQkq, and I could have UCI2WB simply pass that on unmodified. And the same hold for castling moves, where the option -firstFeatures "oocastle=0" would make XBoard write KxR castling moves, which could be passed to the engine unmodified by UCI2WB. So the whole issue can be controlled from WinBoard independently from whether the engine is WB or UCI, as UCI2WB would not change the type of FEN or SAN in translating from WB to UCI.
