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.
Tenjiku Shogi. Fire Demons burn surrounding enemies, Generals capture jumping many pieces. (16x16, Cells: 256) [All Comments] [Add Comment or Rating]A. M. DeWitt wrote on Mon, May 4, 2020 03:16 PM UTC:I managed to make rule-enforcing preset for this game. It enforces almost every rule in this article, from the piece moves down to the Fire Demon's burns. The only rule I could not implement was the rule regarding repeated board positions since it is very complex. So it is up to the players to abide by these.

Tenjiku Shogi. Fire Demons burn surrounding enemies, Generals capture jumping many pieces. (16x16, Cells: 256) [All Comments] [Add Comment or Rating]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?
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 03:09 PM UTC:The rule-enforcing preset now properly enforces promotion rules.
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 Mon, Jun 8, 2020 08:54 PM UTC:Everything should be in order apart from the restrictions against indirect trading of Lions (and the repetition rules, which i won't implement because it's way too complex). 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.

Interactive diagrams. Diagrams that interactively show piece moves.[All Comments] [Add Comment or Rating]A. M. DeWitt wrote on Sun, Jun 21, 2020 03:24 PM UTC:The new AI is pretty impressive. But I must ask you something. As far as I know, there is no easy way to skip a turn with a multi-move piece has this ability. Can this be implemented?
A. M. DeWitt wrote on Sun, Jun 21, 2020 03:24 PM UTC:A. M. DeWitt wrote on Sun, Jun 21, 2020 07:05 PM UTC:It may be rare that you would skip a turn in a Shogi variant, but there are those instances where that is useful.
If you were to implement such a feature, I would suggest keeping the deselection of pieces the same, but having the squares where locust captures are possible trigger the 2nd leg code even when those squares are empty. However, it's important to differentiate between multi-moves that can br triggered by moving to an empty square and those that can only be triggered by capturing (i.e. the Lion's lion power vs. the Heavenly Tetrarch's igui move).

DeWitt wrote on Wed, Jun 24, 2020 09:44 PM UTC:Is there a way to have a piece jump 4 squares diagonally? As it is now, the diagram doesn't appear to have that option as a single move/atom.
A. M. DeWitt wrote on Thu, Jun 25, 2020 02:44 PM UTC:I think adding the Y extension and repeatable suffixes is a good idea. It might also be a good idea to allow the X and Y extensions to be combined in case there is a leap that one extension cannot simplify on its own. It may not be a perfect solution, but it should be good enough to suit the needs of most variants.
Shogi. The Japanese form of Chess, in which players get to keep and replay captured pieces. (9x9, Cells: 81) (Recognized!)[All Comments] [Add Comment or Rating]A. M. DeWitt wrote on Fri, Jul 3, 2020 07:00 PM UTC:I have one question about the rules regarding check. A few sources (i.e. the English Wikipedia page on Shogi) mention a rule against perpetual check, namely making perpetual check four times, or something similar. Yet most of the sources I found do not mention such a rule. So is this supposed rule against perpetual check really a thing?

If you were to capture both a Deva/Teaching King and a Dark Spirit/Buddhist Spirit with a multi-capturing piece such as a Lion or Lion Dog, which piece would you promote it to? 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.
