Weird game..worth analysing!!!!

[matematiko]

Hello all!

Unfortunately I was not expecting the weird end game result, so I do not have any sort of logs.

I was playing in POGO using two of my IDs each on a diferent computer, last move of the game was made by blacks and was a pawn promotion to knight.
Both WinBoards reported a stalemate, which is an incorrect detection, and POGO did not.

Who is the culprit for the wrong end game detection? Rybka3x64? WinBoard? or my ICS Emulator(which has a legality check and end game detection algorythm?

Cheers,

Edit: Both set ups were using polyglot

I would say the most likely explanation is that the promotion was not properly relayed to WB by the ICS emulator, so WinBoard assumed it was promotion to Queen. Hard to say without seeing what position WB was displaying when it made the claim.

[matematiko]

Confirmed, the culprit is my emulator.

Every move is evaluated twice. First when the move is received from WinBoard and second when the move is braodcast by ICS server (POGO or Yahoo in this case).

The problem with pronotions is that my emulator dont know what the pawn was promoted to, so it assumes it was a quen promotion, by the time it receives the coorect piece promotion is too late.

Thanks for looking, I guess I have a weekend project in my hands.

Cheers,

I have learn few things since the last post two years ago. But anyway, that is another story. Today I played a game with WinBoard and no engine of any kind. As usual, I am using my infamous ICS emulator and playing in Yahoo Games.WinBoard was blacks and my other ID was whites using Yahoo's standard java interface and playing also, logically without engine. Whites players makes stupid moves all with the whole purpose to allow blacks player to make the last move in question in this post.

The last move as the picture and the debug file will show is a pawn promotion, I am not using an engine, the option "Always Queen" it is un-ticked and a promotion to knight will be a combination of promotion to knight/checkmate. But viola, WinBoard promotes to queen without my permission, not "Piece Selection" windows pops up. Since the purpose of the silly game was accomplished, I ended the game with whites resigning.

The reason I was experimenting with this is because lot of my friends keep telling me that WinBoard promotes to queen always and the engine freezes when the engine promotes knight, and I keep telling them to un-tick "Always Queen", and few told me they did, but since this happens, what? Every two thousand games or so, it was always hard to follow up, until today a good friend (XsupremeX by the way) told me that this has been an ongoing issue for years but since it happens only every three blue moons nobody has make much noise about it. I do not think my ICS emulator has anything to do with this, but very well might be an ICS only issue.

Thanks for the help.

P.S. I was going to upload the PGN file but I just realize I have not set up WinBoard to save the games, sorry.

[H.G.Muller]

Probably the option -sweepPromotions is in force. Did the text 'to under-promote, pull pawn backwards' appear in the message field when you grabbed the Pawn?

This cannot have anything to do with engines freezing, as it is purely a method for entering user moves. Engines also don't get a promtion popup with -sweepPromotions false. The setting of -alwaysPromoteToQueen should also not effect engine moves. The engine sends promotion moves as text, including a promotion character. If an underpromotion is not understood, it must either be a bug in the WinBoard move parser, or the engine sends a non-compliant move format that is not understood. Of course disagreement on the position between WB and the engine can lead to later 'freezing' of the engine, because it refuses the move WinBoard accepted as illegal (e.g. the engine promoted to a checking Knight, the opponent does a move that doesn't resolve the check, because he thinks there is no check), or WinBoard refuses the engine's move with the Knight. Or the ICS refuses the move. All these situations can lead to stagnation of game play, GUI, engine or ICS all waiting for each other to repent and change their mind.

[matematiko]

Mr. Muller,

The -sweepPromotions did the job when playing without engines, I can not say if this will work for engines or not.

I do want to get a winboard debug file ( and perhaps a polyglot debug file) and get to the bottom of this. Find out if the move parser is at fault or the engine(s) is(are) doing something wrong.

It will be unpractical to play and pray ( play and pray he he he he) that the engines will eventually play a game with a knight promotion. So, what I am going to do is create a stupid.bin book that will make these silly moves and stop book moves just right before the engine sends the move or more accurately move/promotion text string to WinBoard.

I am taking a five days trip to my home country (Mexico), with a little luck I will have these log files tomorrow, but if not I will post them here in a about a week from now.

Best regards and thanks again for taking the time to look into this.

[H.G.Muller]

I can assure you that -sweepPromotions has no effect whatsoever on GUI-engine communication. It only affects whether the promotion popup appears on moves enetered by the user with the mouse. Your approach to find out what exactly happens seems a good one.

Further note that -sweepPromotions true is the recommended mode for running WinBoard, and that in future versions the promotion popup might be removed completely.

Mr. Muller,

I think I found the problem. At the moment this is just theory since I have not done the experiment I mentioned earlier, but while reading your response, it daunted on me that Yahoo sends the pawn move and the desired promoted piece in two separate opcodes ( or commands if you wish). So, in other words, for a period of time, while the opponent (in Yahoo the opponent is expected to be human all the time) is thinking and manually selecting the promoted piece, the board is supposed to shown a pawn in the last rank, then later show the selected piece (queen, rook, etc.) Do you think that this could be the problem?

I do not know how WinBoard communicates with real ICS servers, but I assume that is the same as my emulator, every move takes two steps. Let me explain with a fictitious scenario (but very possible to be the real problem). WinBoard receives the move and promotion to knight from the engine, it does this flawlessly and sends the move/promotion command to ICS (my emulator) which in turn sends the corresponding opcodes to Yahoo. Yahoo validates the moves and accepts it or rejects it ( I assume real ICS do the same), Note: The move legality validation is made by Yahoo Java applet when playing normally as human, and by my emulator when this one is in use, in reality Yahoo server never does any validation, which I think is not the case in ICS. Anyways, back to the scenario: after Yahoo receives the move/promotion, Yahoo broadcasts this move/promotion back to the player that made the move, to the opponent and to every observer (if any). Like I mentioned earlier, Yahoo ( and therefor my emulator) does this in two steps, first the pawn move to the last rank, and then the desired piece for promotion. I believe that is here when WinBoard is choking, not because there is anything wrong with WinBoard, but because the way the move/promotion was handled by my emulator/Yahoo.

If this is the problem, can you elaborate more on how WinBoard is expecting the ICS to send the move/promotion string? I think I can extract this from the source code of my emulator, after all it works flawlessly with queen promotions, but I will love to have your input.

Best regards,

[H.G.Muller]

WinBoard sends moves to the ICS as a simple text line. For promotions, the = sign is mandatory. For the rest the ICS is very forgiving, and accepts almost anything. But WinBoard uses long algebraic, like

a7a8=N

The ICS doesn't send isolated moves; it sends complete boards. This is a legacy from the time when there did not exist any graphical clients, and people used text-based clients like telnet to connect to ICS. Then after every move (including their own moves) a new board had to be 'drawn' by printing ascii characters on their terminal screen. Depending on how capable your text interface was, there were several 'board styles' to make it look good. Later a 'style 12' was added for the benefit of graphical clients. This style packs all info (board position, clocks, side to move, castling rights, e.p. rights, last move in SAN as well as long algebraic, player names, game number, etc.) on a single line of text.

So the proper method would be to let the ICS simulator wait until it knows what the Pawn promotes to, and then send a new board with the promotion piece on it, as well as properly indicated in the last SAN move. (Peculiarly, ICS never put a promotion suffix on the long-algebraic move.) I don't think you can send WinBoard first a faulty or invalid board (with wrong promotion piece, or a last-rank Pawn), and then send it a second board to 'correct' it. Likely it would ignore that second board. (After all, it would have already started the engine after receiving the first board, so it would be far from trivial to correct the situation.)

[matematiko]

Thank you very much Mr. Muller, this is valuable information.

I will re-code after my trip.

Since my weekend starts today, I will wish you and everyone a nice weekend.
