All I really did was copy the Tenjiku Shogi preset's code to this preset and modified the code to suit the needs of the Chu Shogi preset.

A. M. DeWitt wrote on Sun, May 10, 2020 03:18 PM UTC:I also agree that Tenjiku Shogi's promotion rule should be the same as that of Chu Shogi. But for Lions, Horned Falcons, and Soaring Eagles, these rules are a bit vague. Of course, Chu Shogi is of no use to us here since these pieces don't promote in that game. So I decided to follow H. G. Muller's interpretation, which makes the most sense in my opinion.
In his interpretation of the first rule, the piece must start its move outside the promotion zone and end its move inside it. If a piece moves multiple times, the intermediate square(s) would not be considered since the piece did not start or end its move there.
In his interpretation of the second rule, the piece must start in the promotion zone and capture something with its move. It's well established at this point that a capture is any move that removes an enemy piece from the board. This presumably means that if a piece makes a capture on its first step and a non-capture on its second, this would still count as a capture since the piece captured something.
Now let's consider the effects of this interpretation on these scenarios suggested by dax00:
- A Lion that enters the promotion zone on a non-capture and then exits the zone while capturing a piece should be able to promote
- An unpromoted piece that starts in the promotion zone, captures a piece in the promotion zone on its first step, and makes a non-capture on its second step should not be allowed to promote
The first scenario is flawed because it breaks both rules. The Lion did not enter the promotion zone - both its starting square and its destination square are outside of it. This makes the capture on the Lion's second step meaningless.
The second scenario is flawed because it meets the criteria in the second rule. The piece started its move inside the promotion zone and captured something on the way to its destination, so it has the option of promoting on that turn.

A. M. DeWitt wrote on Fri, May 8, 2020 02:19 PM UTC:I completely forgot that the promotion rule was different. I'll get to fixing that right away.
A. M. DeWitt wrote on Fri, May 8, 2020 01:26 PM UTC:One question. Let's say a Lion, Horned Falcon, or Soaring Eagle skips a turn inside its promotion zone (They are the only promotable pieces with this ability). Would that piece be allowed to promote after doing this?
In my rule-enforcing preset for this game, promoting a piece after it skips a turn is currently disallowed. This is because the preset is based on my rule-enforcing preset for Suzumu Shogi (a game which explicitly prohibits promoting after skipping a turn). However, historical sources (which are already terse and/or incomplete) do not elaborate on this particular situation as far as I know. Should I remove the code disallowing promotion after skipping a turn?

Interactive diagrams. Diagrams that interactively show piece moves.[All Comments] [Add Comment or Rating]A. M. DeWitt wrote on Sun, Apr 26, 2020 12:25 AM UTC:About your idea of including piece descriptions in the piece table:
Overall, including piece descriptions in the piece table is a good idea that I think should be implemented. Here are my thoughts on it:
First and foremost, including piece descriptions for a piece in this way should be optional, so you don't have to do it for every single piece in the table, which would be quite tedious, especially for larger games like Hook Shogi and Taishin Shogi. Of course, you can put in default descriptions for predefined pieces, but the programmer should also have the ability to override these. For null descriptions you could simply replace the empty string with a hyphen.
Regarding implementation, I recommend putting all the piece descriptions in an array so you can use JavaScript variables to hold piece descriptions if need be. And when setting piece descriptions in the diagram script, I would suggest putting the descriptions after everything else in the colon-separated list, like so:
name:id:move:image:startingHand:description
This way already existing diagrams won't get screwed up by this new implementation.
If you do implement this, make sure to update this page to include information about it.

The rules state that the promotions of these pieces are contagious, but do not elaborate on which promotion has priority when a multi-capturing piece captures a Deva/Teaching King and a Dark Spirit/Buddhist Spirit in a single move. See the promotion rules in Taishin Shogi for some possibilities.

After this, I moved the black King to e8, and then I moved the black a-Pawn to a1. From there, the askpromote command activated, and I chose the obvious Queen promotion. And then the error occured.

I think this error could also be occuring in the Marseillais Chess preset when given similar situations.

DeWitt wrote on Fri, Nov 8, 2019 08:59 PM UTC:Fergus, I decided to try out your Extra Move Chess Preset, and when I did a pawn promotion with the extra move, the same error that occured when I tried to promote a Soaring Eagle after completing a double move with the mouse popped up, albeit in a different form.

Now I have a very important question to ask: do commands like ask and askpromote only append one move to the list of past moves, or do they append something different? If the latter is the case, then that is the source of the problem. I think the askpromote command might be changing the move immediately preceding the promotion move to a list of all moves in the sequence, including the promotion move, and appending that after the choice is selected instead of just the single promotion move. This effect isn't noticeable with single move promotions because the move before the promotion move is the very first move, and because there is nothing before the first move, the sequence would remain in a legal format after the change.
A. M. DeWitt wrote on Fri, Nov 8, 2019 02:39 AM UTC:These are some very good questions. Here are my answers:
- When I said that the moves of the Fire Demons and the range-jumping generals were unplayable, I was talking about when I was still experimenting with piece moves. This was before I had even joined the Chess Variant Pages. Back then, the range-jumping pieces could only jump a single piece, and I was still experimenting with moves for the Fire Demon. I'll be honest with you - some of them got very crazy. At one time I gave it the move whose XBetza notation was the incredibly long
BsRvW5KaKaaKmabKcaibQ5cafKcafafKcafafafKcafafafafKafcabKafcafKafcafafKafcafafafKafafcabafKafafcabK
afafcafKafafcafafKafafafcabafafKafafafcabafKafafafcabKafafafcafKafafafafcabafafafKafafafafcabafafK
afafafafcabafKafafafafcabK.
I know. It basically defies description.- I prefer the promotion rule from standard Shogi because not only is it much simpler to understand, it is also easier to program in Game Courier. By using the standard prommotion rule all I have to do is keep track of where the piece started and where the piece ended. If I would have used the Chu Shogi promotion rule, it would have made programming the Game Courier preset much more difficult, to say the least.
- The reason the Fire Demon cannot jump is because allowing it to jump wouldn't fit well with the theme of the game being based on Tenjiku Shogi. Furthermore, this would potentially make the game of Mitsugumi Shogi (Suzumu Shogi's smaller counterpart) too fast-paced, even though there is only one Fire Demon in that game. Nonetheless, I have to admit that giving it the move you suggested, at least in Suzumu Shogi, could make for an interesting twist. Though I didn't really plan on giving the Fire Demon jumping moves, it's a good idea to think about.
- Now that I think about it, I think you're right on this one. I'd say it's slightly more valuable than a single Great General or Vice General, and I definitely think it's more valuable than a Rook General or Bishop General. Make no mistake though - even though it is not as powerful as it is in Tenjiku Shogi, the Fire Demon is still a force to be reckoned with. As for the values of the Lion Hawk and the Queen, sure, the Queen can slide in all directions, but the Lion Hawk has a fully-fledged Lion move, plus the move of the Bishop. Because of this, I would, in many cases, find it hard to believe that the Lion Hawk is less valuable than the Queen in Suzumu Shogi. The only reason it would be less valuable in Tenjiku Shogi would be because you are using the TSA rules (Bishop + 2 square area move, rather than Bishop + Lion).

DeWitt wrote on Thu, Nov 7, 2019 12:23 PM UTC:The repeated move is most definitely the problem, but it's the code that is doing this, not me. Other than this bug, the code works perfectly fine. For example, when I type in the move se 3f-4e; se 4e-5d; se$-dest or a similar move, the error doesn't pop up.
A. M. DeWitt wrote on Wed, Nov 6, 2019 09:57 PM UTC:Here is an example of the error that comes up. Note that this only happens after I complete a double move with the mouse and the askpromote command is used after.
ILLEGAL: se 3f-4e; se 3f-4e; se 4e-5d; se$-dest on turn 3:
There was no se on 3f. It is an empty space.
Go back with your browser's BACK button, reload the page, and try again.
For diagnostic purposes, here is the full movelist:
1. se 5m-3k 1... SE 12d-14f 2. se 3k-3f 2... SE 14f-14k 3. se 3f-4e; se 3f-4e; se 4e-5d; se$-dest
In case there is a bug in the code, the settings file can be edited at play.php?game=Suzumu+Shogi&settings=promotest&submit=Edit
As you can see, the first part of the move somehow got repeated during evaluation, which, of course, shouldn't happen. I think it might have something to to with something in the Post-Move sections, but I could be wrong.
