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.

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.

Makes sense, and thank you for the compliment. I figure it would be more approachable and manageable for ChessV than 8-Piece Chess (despite my personal love of the latter).

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.

Hello Fergus, In the game below:

https://www.chessvariants.com/play/pbm/play.php?game=Apothecary+Chess-Classic&log=catugo-panther-2020-252-429

when black tries to move the king, a threefold repetition is claimed. Any idea why?


Fergus Duniho wrote on 2020-09-11 UTC

Any idea why?

The boardflags string was period delimited. Since this value was included in the value of posvar, whose value was being used as a variable name, and array elements are now period delimited, it was treating it as an array element. I stopped this by making the value of boardflags comma delimited.

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

I encountered a bug when using presets I made for large Shogi variants such as Chu Shogi. The bug prevents the blue boxes that highlight legal moves from being displayed for the second part of a double move. Apart from that, everything works normally. I also tried this with the Balanced Marseillais Chess preset, but the bug was not present there. Any ideas as to what's causing this?

Also, the Marseillais Chess preset is exiting with an error as soon as you click the button for it on the game's Game Courier Preset page.

It wasn't correctly handling the move "pass". I made an adjustment so that it now works.

There were a couple typos in the include file for that game. I have now fixed them.

For the log

https://www.chessvariants.com/play/pbm/play.php?game=Apothecary+Chess-Classic&log=catugo-panther-2020-252-429

When I click on 'Kevin Pacey to move', I only get to see the diagram, and the note saying to make and preview my move. Maybe a bug with the preset, or with CVP website/Game Courier? I have a handicap in that with my Windows 7 Windows Explorer browser, I cannot move by mouse-clicking on a piece, if that would have helped in this case (I need to type in my moves, which I'm unable to do in the case of this log's apparent bug).

It worked fine in Firefox, but when I tested Internet Explorer, it did not work. Since I have updated my computer to Windows 10, and Internet Explorer isn't giving me the debugging information I need, I am abandoning support for Internet Explorer. If you're going to stick to Windows 7, you should use a browser that is still kept up-to-date, such as Firefox or Chrome. However, I do recommend updating your computer to Windows 10, because Windows 7 is no longer supported, and it may become increasingly vulnerable to threats on the internet. So, here is a link on how to do that:

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.


Kevin Pacey wrote on 2020-09-15 UTC

I have a Windows 10 laptop (besides the Windows 7 one). I could try to use Windows Edge with it, if that's also an okay browser for with CVP website/Game Courier these days.

In the past I used FireFox after Fergus suggested it, but eventually that browser gave me some sort of troubles on one or more of my computers (not sure if it was on the Windows 7 laptop, which was actually converted from being an original Windows Vista laptop by a family member). A relative told me Chrome could cause me difficulties as well, but I don't know if she was really sure.


Greg Strong wrote on 2020-09-15 UTC

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.


Fergus Duniho wrote on 2020-09-15 UTC

Edge is now Chromium-based and can run all the same extensions as Chrome, as well as its own Microsoft extensions. I got uBlock Origin from the Microsoft store, and I got NoScript from the Chrome store.

MS Edge seems to be the browser that came with my Windows 10 laptop.

Using that particular laptop (which is strangely a bit sluggish when using its built-in mouse, even when I'm not on the internet), I was able to finally reply to Aurelian, in the game log in question. Thanks Greg & Fergus.

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.

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.

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.


Fergus Duniho wrote on 2020-09-18 UTC

It showed up when I looked at it. Since game pages are cached, and scripts are not, there will sometimes be a delay before a new comment shows up on the page it was posted to, but there won't be any delay in it showing up on the comments page. There is no problem with the code. It is simply that the code is not run when displaying a cached page.

I didn't notice any problem when I tried moving as him. If the problem is with using the mouse or touchscreen to move, he should update to a more recent browser or report which browser and device he is using.

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.

That's a feature of the Table rendering method, which the Diagram Designer does not use. Game Courier does not do this for the GIF, JPG, or PNG methods.


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 2020-09-19 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...


Fergus Duniho wrote on 2020-09-19 UTC

That makes perfect sense. While the Game Courier scripts create an HTML page, the drawdiagram.php script used by the Diagram Designer produces an image file. If that image file contains any text, even a white space, it is corrupted.


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?


Fergus Duniho wrote on 2020-09-20 UTC

Yes. Unlike Game Courier, which saves an image file to the server, drawdiagram.php simply becomes the image file. So, it's output has to be a pure image file. Since the set file gets included in it, that set file must be free of any text output.


Greg Strong wrote on 2020-09-20 UTC

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