For those who want to hunt bugs, you can download the executable from

http://home.hccnet.nl/h.g.muller/alpha.tst

Rename it to winboard.exe. You can select FRC from the "new variant ..." menu. It seemed to work, engine-engine as well as Human-engine. (Don't forget to save the debug files!)

Hello HG,

Just a quick question. Does the new version also fix the bug I mentioned
to you about not/wrong giving of time for the 40th/80th etc. move
in regarding time controls with moves/time?

Guenther

No, not yet. I want to overhaul the time-control code anyway, and I postpone ficing the bug till after that.

WinBoard_x already supported time-odds games, where you could write things like 5/2:30 in the time field to give white 5 minutes, and black 2:30. (The time was a string anyway, because of the colon.) I would like to extend that (and change the syntax a little) to allow things like:

40|20 (40 min vs 20 min time odds)
60+40/25 (60 min, andafter that, 40 moves per 25 min repeating)
60|30+40/25|12:30 (60 min followed by 40 moves per 25 min (W) vs 30' + 40m/12.5min (B))
60+40/25+0/5 (60 min followed by 40/25 min and then 5 min for the rest of the game)

The number of moves for the first time-control session already has a separate (numeric) input field (or command-line option), as does the increment (which will be only applied during a 'rest-of-the-game' session). How exactly I have to compensate the time for moves straddling sessions will depend on how I implement that.

I already fixed a bug that I discovered myself (it could long-castle through check on the square left of the King). Make sure you use an executable that you downloaded after I posted this message!

Hi,

I've been waiting to submit chess960 bugs tell shatranj was finished, it may be, i got in to late last night to test, i cant test at work unfortunately, connection to icc is turened off only web pages.

I noticed two issues with winboard_x have not tried f but assume it inherits a lot of code. One is castle moves are sent as O-O O-O-O in home play but as 8 different types of moves like d1g1 etc for icc play. The king typically isnt on the square that the move indicates he is on and you have to check when you get one of these moves if its a legal move for anotehr piece first.

This isnt so bad but adjourned game support is broken. I tried to resume a game and got a could not parst move from ics error when ics loaded the moves of the adjourned game.

Hi H.G.,

I have a problem with setboard command.

Instead, setboard rbnqnkbr/pppppppp/8/8/8/8/PPPPPPPP/RBNQNKBR w HAha - 0 1

I hope to receive, setboard rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1

All engines compatible with Chess960 and Arena receive this.

Hello again,

I am trying to make DanaSah to play in Winboard FRC. I added quotes at the command variant as you indicated in another message.

I have changed the function setboard at the beginning of a game for having full rights of castling, as I have suggested in another forum for compatibility with all engines with protocol xboard playing in Arena FRC, I will send to these engines in the setboard command "KQkq".

After doing this, I have a small problem when playing as a human and engine with Black. After the commands "time" and "otime", the engine does not start (if it does well in the normal variants)

If I decide that the engine start a game with White, then I if get the command "go", in this case you will see that the engine begins to play and that castling and recognizes the castling the contrary.

In game 1 it seems your engine suddenly exits, after receiving the user move d2d3. The GemeEnds() call with argument NULL suggest that WinBoard could no longer read from the output pipe of the engine. But from the debug you can see that WinBoard really did send the move.

So I think the problem is in your engine. It somehow does not accept the move, and even crashes from it. It should have known that white was on move from the FEN. Perhaps it gets confused by the 'B' in the castling rights, mistaken it for black-to-move?

I already commented on the FRC castling-rights notation on CCC. The engine has to be able to understand the A-Ha-h notation, or your setboard would fail for non-opening positions like

[diag]3kq3/3pp3/8/8/1PP2PP1/8/8/1K3RR1 w[/diag]

where during the game white moved one Rook from a1 to g1. Even Arena will use F to indicate the short castling right for this position, if the King and Rook on f1 have not yet been moved.

If you only want to work setboard correctly for opening positions, you can indeed ignore all FEN fields after the board, as you can be sure that in the opening white has the move, castling with both Rooks is allowed, e.p. is not possible, the reversible-ply counter is at 0 and it is the first move. Reading the castling field of the FEN is only useful for the purpose of handling positions that might not be openings.

Actually, it won't.

Not surprising, as Arena goes out of its way to be incompatible with the official UCI protocol by rejecting king-takes-rook and neglecting to set UCI_Chess960.

Posted: **19 Jan 2008, 14:13**

Well, this is definitely wrong. From the Q you cannot see if you can castle with Ra1 or with Rb1. The x-FEN standard clearly specifies that Q would mean the outer-most Rook (so Ra1 here) has the castling rights. As I understood it, Shredder-FEN doesn't ever use K and Q.

If Arena is buggy in this respect, we should not pay attention to what it does, as the aim is to have a system that works, and not to introduce the same bugs to remain compatible!

Well, first let me say that I remain neutral on the war-x-FEN and Shredder-FEN. My opinion is that to support the protocol you have to change something about your function FEN for x-FEN and for Shredder-FEN.

If an engine plays Teemu moves in the starting position that has given, then the engine will have no problem in knowing how the castle must be, as it has moved a rook, it knows that this rook he can not castle, is the engine internally who leads the account.

If we copy the FEN to the clipboard, we have:
brqknrnb/2p1pppp/pp6/8/PP1B1P2/3p4/2PPP1PP/RRQKN1NB b - - 1 7

Arena does not indicate anything about the castles, so it is not where the FEN has gone from Teemu.

We can edit a position chess960 in Arena and give castling rights, which would have the FEN to Teemu.

brqknrnb/2p1pppp/pp6/8/PP1B1P2/3p4/2PPP1PP/RRQKN1NB b Qkq - 1 7

The FEN is incomplete, as you said Teemu and HG

The correct x-FEN would:
brqknrnb/2p1pppp/pp6/8/PP1B1P2/3p4/2PPP1PP/RRQKN1NB b Bkq - 1 7

The correct shredder-FEN would:
brqknrnb/2p1pppp/pp6/8/PP1B1P2/3p4/2PPP1PP/RRQKN1NB b Bbf - 1 7

Well, then Arena fails to edit the position because Arena forget this possibility that there may be 2 rooks on one side. (or because they still do not support X-FEN)

But you (HG) have a error, is that this error in Arena is also an error in Winboard, Winboard if we edit a position not question that the rook is good, the GUI Fritz also no asked its configuration and only GUI Shredder it does.

The only full GUI to play chess960 is Shredder GUI, therefore the engines xboard not currently have a full GUI for it, only to play complete games.

Posted: **20 Jan 2008, 15:04**

When I edit the position (Teemu) in Winboard, I receive:

brqknrnb/2p1pppp/pp6/8/PP1B1P2/3p4/2PPP1PP/RRQKN1NB b HAha - 0 1

Of course, this is wrong.

The fault of Arena is that they still do not support XFEN (and ShredderFEN?) and maybe with this they not ask which of the 2 rooks make castling. This is the same mistake made by Fritz GUI although they tend to using ShredderFEN

The Winboard fault is that even his edit has no chance of castling rights, nor can indicate other things ep, number (played) or rule of the 50 moves.

Posted: **20 Jan 2008, 17:42**

The 'edit' command I can actually fix, if there is any demand for this. In normal Chess, engines are supposed to assume that Rooks and King starting on the square of the initial position do have castling rights. For positions where the corresponding rights do not exist, because the piece was moved, biut somehow moved back, I could use a similar kludge as old WinBoard uses to load a position where black is to move. It then sets up a normal position, (with 'new'), plays a2a3, and then uses the 'edit' menu to clear the board and set up the new position.

Similarly, castling rights could be destroyed by never putting Rooks that should not have castling rights in a corner, but set up another position than the requested one, and use 'force' mode after the edit to move the Rooks to their corner (so they get there without having castling rights).

Similarly, I could enter the move number and reversible plies by first 'new', 'force', and then playing the Knights up and down for the required number of moves (throwing in a Pawn move at the right moment to set the 50-move counter), and only then start 'edit'. For e.p. rights I would simply set up the position before the double pawn move, and play the latter in 'force' mode.

A hideous kludge, of course. But it would solve all problems for existing engines, while staying completely within protocol 1.

For FRC it would be more difficult, as the engine is not aware of the initial position. But FRC engines using 'edit' mode should assume that any Rook on the back rank is virgin. When this is not desired, WB could set up the Rooks elsewhere, and move them to the requested square through force.

I wonder if this would be worth it though.

The error was in the FEN reader: it assumed that K always meant h-file, and Q always a-file. This is of course not correct in x-FEN, so it was only correctly reading Shredder-FEN. And if the initial rights were not correct, playing the moves and saving the FEN kept the faulty rights.

I fixed it now, by actually searching for the outermost Rook when K or Q are encountered in the castling-rights field. After pasting in the game above, it now saves the FEN:
brqknrnb/2p1pppp/pp6/8/PP1B1P2/3p4/2PPP1PP/RRQKN1NB b Bfb - 1 7

The corrected WinBoard_F executable can be downloaded from http://home.hccnet.nl/h.g.muller/alpha.tst (as usual).

Hmm? Is the outermost (white) rook really on b?

Posted: **20 Jan 2008, 19:40**

It was in the original position, described by the FEN with the Q castling right.

No, and that's why Arena's FEN was wrong.

Posted: **20 Jan 2008, 19:47**

Ok, it seems I just misunderstood your "actually searching for the outermost Rook".

Posted: **20 Jan 2008, 20:20**

I see. So for clarity: that applies to the routine that reads the FEN. While writing the FEN it just uses the rights (stored internally as file numbers) that WinBoard has kept during the game, and writes those. It would do that even if there are no Rooks at all in those files.

Note that WinBoard_F does not check for castling rights given as A-H if there is a Rook in that file. So in principle it is capable of supporting games where you can castle with pieces other than Rooks. (The current MakeMove does recognize such moves as castlings, though. You would simply capture your own piece!

)

Note that in KnightMate the Royal Knight (represented as Unicorn) can castle with its Rooks. Thinking of it, this might not be properly implemented yet...

Posted: **20 Jan 2008, 21:36**

OK, now I understand.

We can give to Winboard a position Shredder-FEN, we are going to the menu, "File" and "Paste Position From Clipboard".

Then Winboard sent to the command setboard with proper rights of castling in the same format Shredder-FEN.

We can not use in Winboard "Edit Position" of menu "Mode", in this way we can not give all information on the position.

In Arena, the routine that reads the FEN, does not recognize xFEN nor ShredderFEN.

Only one thing, I get the command setboard 2 times, the first with castling rights and the second without them, the second should not have those rights also? and perhaps should not coincide the turn and last 2 numbers with the FEN of clipboard?
