cutechess/fishtest issued Illegal PV warnings for Shogi

[notruck]

The vast majority of Shogi (and shogi-family) games complete without any warning, but this one game (round 87) issued quite a bunch.

In particular, it really seems to dislike this i8h8 move. The log below is unedited and copied verbatim:

[ianfab]

Thanks for reporting. The fourfold adjudication looks correct, and perhaps cutechess treats any move in the PV after a fourfold repetition as illegal (whereas in SF play can theoretically continue). I think it probably is not an issue and might just be related to how SF creates the PV line from the TT, but I will need to check in more detail to confirm that it really is not an issue.

[alwey]

I think this is more of a cutechess issue. I cannot see anything wrong with stockfish.

[alwey]

Okay, it is what @ianfab said: The PV extends past the 4-fold repetition. Giving check +Rh8 (i8h8) would then be an illegal perpetual.

[notruck]

Thanks for investigating! This also appears to be the same issue, although cutechess adjudicated a result this time around.

They're repeating the exchange of Golds on d8 at the end.

Sorry about the long output :D but I guess otherwise I would have missed those warnings were they shorter.

This looks more problematic as cutechess and Fairy-Stockfish seem to disagree on the rules here. I suspect the definition of perpetual check might differ. In Fairy-Stockfish a perpetual check is defined as a (fourfold) repetition of a position where all moves of one side between the occurences of the positions were checks. This to my understanding is in line with the FESA rules, see articles 3.12 and 5.2.

3.12 A player is not allowed to continuously check the opponent’s king (perpetual check) such that the
same position is repeated more than three times.
5.2 [...] Note that some of the moves producing the repetition can be checks, but
continuous checks by one side are illegal

@notruck : Thank you for reporting this new problem.

@ianfab : Thank you for the clarification. Indeed, cutechess needs to check whether the sequence of checks is continuous, FESA rules 5.2. I did not have a copy of the FESA rules yet.

I will try to come up with a patch for cutechess as soon as possible.

Dobutsu is generating a lot of warnings. I have only partial logs as the output is so copious this time.

Searching for the "Finished game x" string, many games ended with an illegal move: (none).

Thanks, in the PGN I identified a couple of issues. From my perspective only for the first one it is unclear whether the issue is in Fairy-Stockfish or cutechess, since most phrasings of the rules are not very clear on that. The other ones to me look like bugs in cutechess. @alwey Can you please have a look?

[alwey]

From my perspective only for the first one it is unclear whether the issue is in Fairy-Stockfish or cutechess, since most phrasings of the rules are not very clear on that. The other ones to me look like bugs in cutechess. @alwey Can you please have a look?

underpromotion: Is a chick allowed to refrain from promotion when moving to the back rank?

The rules from second sources are not quite clear. The official rules say that a Chick promotes moving onto the final rank: When implementing this I used the Google translations to English and to German of the official rules page and found no problem here. From the Google translation of the official rules page

ひよこが相手のエリア（一段目の空や森）まですすむと、駒をひっくり返してニワトリに成長！
When the chick goes to the opponent's area (the sky and forest on the first stage), the piece is turned over and grows into a chicken!

...

checkmate detection

I think in this case cutechess is right, because in Dobutsu Shogi the Lion may expose itself to attack and can move to b2 or capture on c2 in round 1 and the Lion has 4 moves in round 5.

stalemate detection

For the same reason there is no stalemate, so in round 58 the Lion has 5 moves.

From the original rules page and Google translation:

＜つかまえかた・つかいかた＞

・ひとつのマスに２ひきのどうぶつは入れません。
・相手のどうぶつがいるマスに自分の仲間がすすむときは、そのどうぶつをつかまえて仲間にできます。つかまえたどうぶつは盤の上から取り、仲間として自分の手もとに置きます。＝『持ち駒』(もちごま）
・持ち駒は、自分の番のときに、空いている好きなマスに置けます。

＜かちまけ＞

1.　相手の「ライオン」を先につかまえたほうが勝ち!!　
2.　自分の「ライオン」が、相手のエリア(空か森)まで先にすすめたら勝ち!!
　　　ただし、すすめてもすぐに「ライオン」がつかまってしまう場合は負けです。

☆「ライオン」をつかまえたときは『キャッチ!!』相手のエリアまで無事にすすめたら『トライ!!』と言いましょう。

<How to catch / use>

・ You cannot put two animals in one square.
・ When your companion advances to the square where the opponent's animal is, you can catch the animal and make it a companion. Take the caught animal from the top of the board and keep it in your hand as a companion. = "Mochigoma"
・ You can place your pieces in any free space when it's your turn.

1. The one who catches the opponent's "lion" first wins !!
2. If your "lion" advances to the opponent's area (sky or forest) first, you win !!
   However, if the "lion" is caught immediately after recommending it, you will lose.

☆ When you catch a "lion", say "catch !!" and say "try !!" when you reach the opponent's area safely.

-- Now for some cutechess errors:

chick drop on back rank

Round 35: This is a cutechess error. I forgot this. I will change the code so that the Chick can be dropped onto the highest rank.

two chicks on one file

Rounds 42 and 59: Cutechess errors. This also slipped through when I implemented DobutsuBoard: There is no "nifu" rule in Dobutsu Shogi, so two Chicks of the same colour are allowed to be on the same file. I will change this.

I found an additional weakness in cutechess: When the opponent can catch a Lion that reached the farthest rank but fails to do so the game is only adjudicated late. The winning side has to make a superfluous move with some piece without removing the Lion from the farthest rank. So I have some work to do.

EDIT: I found the "mate by Pawn drop is forbidden" (uchi-fu-zume) rule active in cutechess, which is also a problem.

I just found videos about Dobutsu Shogi on youtube. The first video by account "Dobutsu Shogi" gives an introduction to the rules. There are equivalent videos in other languages.

A second video showis the implementation of the game on a N* console. At 1:22 you will find the chick promotion to chicken. At 1:42 Sky Team's Lion exposes himself to attack by Land Team's Lion and Land Team's Giraffe. The latter captures the Lion - game over. At 2:05 the rule of the Lion winning (or losing if captured immediately) on the far rank is shown.
