Versions after Winboard 8.0 can't play Fisher random in FICS

[lantonov]

Sorry, read versions after Winboard 4.8.0 (e.g. 4.9.x). When I am white in FRC in FICS engine does not move and I have to abort. Winboard 4.8.0 starts and plays normally in this variant.

[H.G.Muller]

What engine are you using? And if it is UCI, are you using Polyglot or UCI2WB as adapter?

[lantonov]

I use Stockfish latest development version (UCI) with Polyglot adaptor.
The starting batch file is:
start winboard[version] -fcp "polyglot stockfish.ini" -fd C:\WinBoard /fNoOwnBookUCI /sNoOwnBookUCI /firstOptions {Syzygy50MoveRule=true,SyzygyProbeDepth=10,SyzygyProbeLimit=5} /zp /ics /icshost freechess.org /icsport=5000 /icshelper=timeseal.exe /icslogon=ics-fishtest.ini /zippyAcceptOnly lantonov /zippyAbort True /zippyGameStart="say [...]" /zippyGameEnd "say [...]"

[H.G.Muller]

OK. That makes it rather strange. I am not aware I changed anything specific to FRC between 4.8.0 and 4.9.0; the difference was mostly better piece-graphics handling in the XBoard front-end, which is why I did not even release it as a new WinBoard. I did release the development version as the WinBoard-AA beta package, though, where it uses UCI2WB rather than Polyglot as UCI adapter. And it would be quite possible that UCI2WB is defective for FRC. But if you use Polyglot this can be ruled out.

Could you make a debug log of a case where the engine refuses to start, by running WinBoard with the extra option -debug, and then posting the winboard.debug file that will be created here?

[lantonov]

Sure, I will do it right away.
Now I started it like this:
start winboard-7dda741 -debug -fcp "polyglot stockfish.ini" -fd C:\WinBoard [...]
Started normally this time (?) but in the chat window it wrote as if I have asked a draw at the start:
Issuing: FishTest (2982) exeComp (2500) rated wild 3 0 Loaded from wild/fr.
--** exeComp is a computer **--
Your wild rating will change: Win: +2, Draw: -17, Loss: -36
Your new RD will be 82.3
fics%
exeComp accepts the match offer.

Creating: exeComp (2500) FishTest (2982) rated wild/fr 3 0
{Game 77 (exeComp vs. FishTest) Creating rated wild/fr match.}

Game 77: A disconnection will be considered a forfeit.
fics% (told exeComp, who is playing)
fics% Draw request sent.
fics%
exeComp declines the draw request.
fics% {Game 77 (exeComp vs. FishTest) exeComp checkmated} 0-1

Such draw request does not appear with WB 4.8.0. Next is the beginning of the debug file (too long for the window to accept all):

The game started because the other computer (execomp) was white. It doesn't start when my computer is white.
Looking at the debug file, I found also a difference in how the fens are set up:
In 4.9.1 - 44639 >first : setboard rnbbqknr/pppppppp/8/8/8/8/PPPPPPPP/RNBBQKNR w HAha - 157+0 0 1
In 4.8.0 - 54585 >first : setboard rbbknnqr/pppppppp/8/8/8/8/PPPPPPPP/RBBKNNQR w HAha - 0 1
This problem also occurred before with Stockfish and asmFish but maybe I posted it in the wrong section:
viewtopic.php?f=19&t=53936

[H.G.Muller]

OK, I see. The fishy part of the debug was:

Code: Select all

44639 >first : playother

Here Polyglot immediately claims a 50-move draw with the 1/2-1/2 command, and then refuses to play on.

But as you pointed out, this is not Polyglot's fault, but the consequence of Polyglot receiving a faulty FEN. The 157+0 field should not have been there, but now that it is Polyglot interprets it as the 50-move counter. It also explains why it does work with black: the opponent will almost always start with a Pawn move, which resets the counter no matter how large it initially was.

This FEN field should only have been present in variant 3checks, where it indicates the number of checks each side still needs to win. (So for a starting position it would say 3+3.) That it is also sent for FRC is indeed a WinBoard bug. And I probably added that field recently, when Stockfish learned to play 3checks.

Thanks for reporting this!

[lantonov]

Thanks for being always so kind and helpful.
I suspect the problematic patch is from 13 Jan 2017
Implement check-count field in FENs

[lantonov]

This works (although not very elegant):
backend.c below line 18700

Code: Select all

    i = boards[move][CHECK_COUNT];
    if(i && gameInfo.variant == Variant3Check) {
   sprintf(p, "%d+%d ", i&255, i>>8);
   while(*p) p++;
    }

[H.G.Muller]

Indeed, that would solve the problem with the FEN. But there could be other problems. The underlying reason for all this is that the CHECK_COUNT variable in the game state is not initialized when you start an ICS game. In local games InitPosition() would take care of that, and only initialize it to a non-zero value for the initial position of 3check. But in ICS games the flow of information is different: the ICS will send a board to WinBoard after every move, and the new position is obtained by parsing this board, rather than derived from the previous position by applying the move. Applying the move updates the CHECK_COUNT in 3checks. But the board sent by the ICS does not contain any info regarding the number of checks; you would have to deduce that from the game history. This also applies for the initial position; it is just a position received from the ICS like any other position. The current ParseBoard12() leaves CHECK_COUNT undefined. (And it uses a local variable as temporary to build the board, which has undefined starting values for every board element.)

I had a similar problem in Crazyhouse, where the ICS board doesn't show whether a piece is a promoted Pawn or not (which I want to show in WinBoard). I had to add code in the ParseBoard12() to extract that info from WinBoards record of the previous position. For FRC castling rights too, btw. Something similar will have to be done for the check count, or it might revert to a random value after every move even if the initial position set it right. And apart from the FEN sent to the engine the value might affect adjudication in 3check. So 3check might be broken even more than FRC, in ICS games.

Unfortunately I have little time now, as my plane to Macau leaves this afternoon. I will take a look at it after the Computer Olympiad.
