Ok, I have removed extra whitespace from all piece sets and verified that they all now work in diagram designer.


Greg Strong wrote on 2020-09-19 UTC

I am referring to a space in the php file that defines the piece set, not the image file created by the script. The diagram designer executes php code to dynamically create and return a binary image, right? Why would whitespace in the php source code of a program affect its output?

Update: Ok, maybe I see. Since the space is outside the ?> it gets incorporated into the output stream?


Greg Strong wrote on 2020-09-19 UTC

With some extensive testing I've been able to figure out the issue, although I don't understand it. The piece sets that don't work with diagram designer all have an extra carriage return at the end. Remove it, and they work fine. Take a file that works, put an extra blank line after the ?> line, and it breaks. Very odd for whitespace to break code...


Greg Strong wrote on 2020-09-18 UTC

Oh, ok. I guess that makes sense. Unfortunately, that means the diagram designer can't show uncheckered boards, but that's not critical.


Greg Strong wrote on 2020-09-18 UTC

Some piece sets still won't render a board with diagram designer although all the individual pieces show correctly. My earlier speculation that it involves sets with "for" in the title appears to be incorrect, or there is more to it. The ones that fail all seem to have "for" in the name, but some others containing "for" do work.

Also, in Game Courier, if there is only one square color, it will draw outlines around the squares as shown in this preset: https://www.chessvariants.com/play/pbm/play.php?game%3DMaorider+Chess%26settings%3Ddefault But Diagram Designer doesn't do this. It just shows a solid board with nothing to separate the squares.

Something seems wrong with the code that displays comments on a game page. This page: https://www.chessvariants.com/41.dir/2pipe.html does not show my most recent comment on the page, but if you view all comments, then it does appear.

Although the rules don't state it, pawns on the first rank can move two spaces, subject to en passant capture. I determined this by looking at the Zillions implementation.

 Author: Hans L. Bodlaender. Inventor: Jari  Huikari. Insane. Pieces change to random type when they move. With program playing this variant.[All Comments] [Add Comment or Rating]
Greg Strong wrote on 2020-09-17 UTC

What if a piece randomly changes into a pawn on the first or second rank? Can it then move two spaces? What about the eighth rank? Does it then promote? Or is it stuck forever?

The rules don't seem to address any of this.

Edge should work fine but I don't know if it has plug-ins for ad blockers, nor do I know if it runs in a security sandbox. (It's Microsoft and they are not exactly known for putting security first. Or even second.) These are the important things if you are going to continue to run Win7. Firefox should work for you just fine, although Chrome should as well.


Greg Strong wrote on 2020-09-14 UTC

If you are still running Windows 7, you should discontinue use of Internet Explorer. I would recommend you install Firefox, and then add the uBlock Origin extension (an ad blocker). Firefox runs in a security sandbox, and the ad blocker will reduce the chances of even viewing malware in the first place. Running Windows 7 still won't be 100% safe, but this will be much, much better than running IE. Under no circumstances should you run IE on Win7 at this point.

Greg Strong wrote on 2020-09-11 UTC

I have rewritten most of this page with updated information from Jean-Louis Cazaux's excellent new book A World of Chess, co-authored with Rick Knowlton. The previous version had the initial setup incorrect (both of a player's bishops on the same color) and incorrectly identified the author of a book on chess variants as the game's inventor. Additional historical information has also been added.

I still need to make a similar revision to The Emperor's Game

Greg Strong wrote on 2020-09-11 UTC

This page is a mess which, in my view, should not have been published. If there are over 30 variants to Tiger Chess, they should be listed on that page, not here, were no one would find them anyway - since the name of the page, "Summary of Game variations, Clock times and other Information", does not indicate what it is.

If you'd like to format this variant information in reasonable HTML, I will happily add it to the bottom of the Tiger Chess page. But I am scheduling this page for deletion a month from now. If nothing further is done, I will add a comment to the Tiger Chess page linking to archive.org's copy of this page so that those interested in Tiger Chess will still be able to find it.

Posted. Interesting looking game!

I converted the graphics to PNG so I could make the backgrounds transparent. The backgrounds were white and the web page background is not white. I may make some small edits to the HTML formatting later, but for now it is pretty good.

You're welcome.

Yes, ChessV is still in development, off-and-on. New versions will be forthcoming, but I make no guarantees about what they will include. The effort involved with programming support for the Lancer is probably "moderate". But there is an almost infinite list of things that should be added, and honestly, there are many that are desired by a larger group of users. But it may happen at some point. It is an interesting piece.

 By Omega  Fallon. Leaping chess. (Updated!) Chess centered around the gimmick of knight-like pieces.[All Comments] [Add Comment or Rating]
Greg Strong wrote on 2020-09-11 UTC

Hello,

The first step to getting this in a state to be published is including a diagram of the starting position. I have edited the page to include a diagram with how I believe the pieces are supposed to be placed, and using the graphics from the Alfaerie set that are typically used for the piece described, or the closest available. Please let me know if this looks reasonable.

Also, I think Leaping Chess is not really a good name for this variant. While there is no "Leaping Chess", there is a "Leap Chess", a "LeaperChess", and a "Leapers Chess". And I think the name "Leaping Chess" does not describe this game very well. Such a name implies something close to chess, but with extra leaping. This game is a significant departure from chess, with many new elements.

Some notes on your pieces... The piece you call the Advisor is usually called the Sergeant. (No need to use this name, but I wanted to make you aware in case you want to.) Also, personally, I would use a different name from Zebra. This is a common piece that is a (3,2) leaper. Using the name or the graphic could make the game harder to learn - players of chess variants expect the Zebra to move a certain way. Maybe "Horse"? (In the diagram, I used the Alfaerie Horse image, not the Zebra image.)

I think this game may have potential, but it could use some play-testing, which can be done on game courier. One thing I do not like is the arbitrary rule that is needed so Grasshoppers do not capture Rooks on the first moves. Additional arbitrary rules seldom lead to good, satisifying games. I would try to change the starting position so this is not necessary. Maybe move them to the first rank, and to make space, make only one catapult and elephant? There are many other pieces of which you have only one. These pieces are not colorbound so I don't think you need two.

Yes, "Full Cavalry" is just fine. I'll try to review it tonight. On a quick look it appeared fine.


Greg Strong wrote on 2020-09-10 UTC

Since members submitting new games with names that are already used has become a common problem, I have added a new alert message to the member submission page to make users aware of the issue.

Greg Strong wrote on 2020-09-10 UTC

I have not reviewed the page, but an issue is that a game named Copycat Chess already exists, so you will need to select another name. I can rename the page for you. You could always use Fallon's Copycat Chess if you do not have another idea.


Apothecary chess preset error[Subject Thread] [Add Response]
Greg Strong wrote on 2020-09-04 UTC

Yes. As I posted earlier, there was actually no problem with the preset. The problem was that there was an actual illegal move in the game log. The illegal move was originally ignored, but when you fixed it, it would not load the game (which is correct behavior.)

Greg Strong wrote on 2020-09-02 UTC

This link is dead, and since it is a link to a RAR file, it is not captured on archive.org.

Per Wikipedia, however, this is a variant of Cambodian Chess, which is itself a variant of Makruk. Cambodian Chess probably deserves a page (we have a Zillions file and a Java file, but not a game page), so I will make one. This variant should be mentioned on said page, but I do not think deserves a page of its own. When I have made that page, I will just delete this one.

 Author: Fergus  Duniho and Antoine  Fourrière. Inventor: David  Short. Double Chess. FIDE Chess x 2(with extra queen replacing what would be an extra king).[All Comments] [Add Comment or Rating]
Greg Strong wrote on 2020-09-02 UTC

I just tested this preset and it seems to mostly work. I tried all four castlings (king-side and queen-side, close-rook and far-rook) and they all worked. Moves often weren't displayed correctly, though. Queen-side castling with the close rook displays and works fine. King-side castling with the close rook does not display as legal, but it will work if you tell it to try anyway. King-side castling with the far rook does not display but will work. Queen-side castling with the far rook (a) does not display the legal move, but it will work anyway, and (b) displays a king move to the g-file as legal that should not work, but does.

Kevin also previously noted a castling in a real game that should have worked but didn't. This is Antoine's preset and he is no longer active. I will try to look at it in a few days if no one else does, but it would be great if someone else could take a look.

Greg Strong wrote on 2020-09-02 UTC

I have updated this page to replace the position diagrams, previously drawn as ASCII graphics, with images dynamically generated by the Diagram Designer.  I also added a link to download the game as a ChessV saved game file to facilitate further analysis. 

I've always been a fan of David Short's Double Chess (16 x 8).  This is both the first time I have seen a game go this long, and the first time I have seen a player castle with the far rook.
