Duck Chess

JohnWoe · Post by **JohnWoe** » Sun Oct 30, 2022 6:41 pm

Yes, I compiled wrong version. Now I see DuckChess. I don't want to play but test my engine.

I use uci2wb

./xboard -fcp "uci2wb ./mayhem-duck-1.1-x86-linux-classic-64bit" -pieceImageDirectory 'svg' -debug

I guess some variant stuff in MayhemDuck needs recompiling. Somehow xiangqi is "supported". It's not. MayhemDuck only plays DuckChess. Nothing else. Debug:

Well, if an UCI engine does not announce what variant it plays, UCI2WB will assume it can be a Chess or a Xiangqi engine (as these commonly use UCI).

Are you sure Mayhem annonces it plays Duck Chess, by having 'duck' as one of the possible choices in the UCI_Variant option?

After Herculean effort I managed to get it work.
I compiled uci2wb also.
So it was duck in variants.
But XBoard doesn't use the correct form of notation. MayhemDuck expects e2e4@e6. I want to block e6.
MayhemDuck is very picky on moves entered as Mayhem.

Well, WB protocol uses a comma, and is pretty picky too. An @ sign is reserved for drop moves. Do not use it for other cases.

You will also have to repeat the to-square. Like e2e4,e4f5 if you want to place the Duck on f5.

Hi HG, is it possible to get a Winboard 4.9 binary with duck chess support?

hgm · Post by **hgm** » Sat Nov 05, 2022 9:27 am

Probably not today. I would still have to port the modifications in the WinBoard front end from the Alien Edition to the v4.9.x branch, and I have a busy schedule today. And I would want to have Duck Chess be selectable from the menu. But if I am going to alter the New Variant dialog, I want to alter it such that the engine-defined variants can be selected from a combobox, as some engines now support a ridiculously large number of variants, for which radio buttons are no longer practical. But I will work on it.

Okay, I'm not in any hurry for it, but if you get to it someday, great.

OK, I brewed something, and it actually works. I am sad to say that the XBoard version in my repository did not. I had no Duck Chess engine on Linux, so I had not tested it, but when I equiped it with a WinBoard front end it turned out to contain several crippling bugs. Actually it would not even compile, due to another untested WinBoard front-end patch.

I uploaded it to http://hgm.nubati.net/Duck2.zip . It has duck images at sizes petite (33x33), middling (49x49) and bulky (72x72). At other sizes the Duck shows up as a black hole. (But apart from that it should still work.

[Edit] The bug-fixes are now in my on-line repository, so an XBoard built from the v4.9.x branch there should now work too.

Thank you! For a test, a two-games match Quack 1.3b vs DuckChess.zrf (Zillions of games), I think, in this chess variant it is the first engine match ever.

[Event "Edited game"]
[Site "DESKTOP-UG2MCF4"]
[Date "2022.11.06"]
[Round "1"]
[White "Quack 1.3b-"]
[Black "DuckChess.zrf"]
[Result "0-1"]
[Variant "duck"]

1. Nc3,f3 Nf6,b5 2. Nf3,d4 Ng4,d5 3. e4,g1 c6,g8 4. b3,f6 h6,d3 5. d2d4,e3

This was an illegal move from White, the pawn cannot jump over the duck on d3,
so Black won

[Event "Edited game"]
[Site "DESKTOP-UG2MCF4"]
[Date "2022.11.06"]
[Round "2"]
[White "DuckChess.zrf"]
[Black "Quack 1.3b"]
[Result "1-0"]
[Variant "duck"]

1. Nc3,b5 e5,c6 2. Nf3,e7 Nc6,e3 3. d3,f6 Bb4,g4 4. Nd5,d2 Bc5,f4 5. Be3,d4 a5,d6
6. Bxc5,f6 b5,h6 7. e4,f6 g6,b3 8. Kd2,f6 Nge7,b4 9. Nf6,f8#

In its engine output Quack wrote "Black resigns" - after it was mated.
So the match ended 2-0 for Zillions. But I think, the bug fixes (that only knights can jump over the duck, and to be able to recognize an immediate mate) won't be too hard, and that in one of the next versions you will manage to catch up with or to surpass the Zillions version

Thank you HG.

I ran into the problem below using my own duck chess engine (work in progress):
Second engine sent move g8f6,f6f4. But WinBoard sent g8f6,f4g6 to the first engine instead of g8f6,f6f4.

My engine sends moves using two lines, since I followed the example of Quack engine.
move g8f6,
move f6f4
