Well, in general it is possible to paste the HTML of an existing Diagram into the Play-Test Applet, and then use the GAME code button. But this only works for 'run-of-the-mill' variants that the Play-Test Applet could generate. (I.e. pieces that move differently, but otherwise normal rules.) Promotion restrictions, multiple royalty or anti-trading rules can be added by post-editing of the generated GAME code (modifying or adding some tables).

I am not sure if all your variants are of that type. When the ID required custom JavaScript, no GAME code will be generated to perform its function.

@H.G.
Thanks, I have done, works very well.
Now it would be the topping if there could be a way to get the game code for Game Courier. Do you have a workable suggestion for a non-expert like me?

Would it be very naughty to ask you to provide me with the HTML-codes you have already created? This would be for the variants Avatar Chess, Borderline, Bull's eye and Conquer. It would be great if I could make the variants playable in my pages with your help. (If yes via e-mail perhaps?)

You can simply get the HTML code for the Diagrams by asking the browser to display the 'Page Source', and then copy-paste the relevant part of the HTML code that is displayed. (Search for "idiagram" on the page, because CVP pages always contain an enormous amount of HTML for displaying the menu bar, and the user text will start only after that.)

@H.G.
After my first trials with the 'Play-test applet' and the conversion to Game Courier thanks to the game code provided by the play-test applet, I have tried my luck with my other variants. To be honest, I am quite stumped and very sure that I will never get it right. Hence my question - better request:

If that is too much to ask, then please forget my request.

Short feedback: The 'Move definition aid' is a great tool. To get the Betza string for the Enhanced Pawn finally working it was necessary to define the standard pawn first and then to add the enhanced capturing possibilities. This probably has something to do with the en-passant rule. Maybe that is self-evident for the insider, for me it took some time. Anyway, the following string finally worked: fmWifmnDfceFscWbcF

That said, your small image seems to have worked. Perhaps the data of the image itself works, but for larger images you run into comment length limits in the scripts/database?

Yes, that's how it will be. Thanks Ben.

I don't think we have a way to upload images directly from our editor (ckeditor); you have to have a valid web url for the image.

I've been trying to reply for some time, but I can't get more complex answers with pictures posted. What could be the reason for this?

In the Game Courier Preset I don't find this checkbox and what happens if the checkbox is not ticked?

Then all moves would be rejected, because Game Courier would have already performed those before the rule checking code is activated, so that the piece would already be gone, and moving empty squares is illegal.

But the button should be the rightmost of the three in the 'Advanced' section, when you hit 'Edit' after loading the preset:

@H.G.
In the explanations for the Play-test applet for chess variants, under Automating Game Courier/GAME-Code, it says: 'You will have to tick the checkbox "Do not include moves in code" just above the Pre-Game section'.

Indeed, the Play-Test applet seems to be ingenious. You just have to understand the Betza notation, which is what I'm dealing with at the moment.

You said that in the play-test applet you only have to change the pawn movement to fmWcFscW. Do I understand correctly that this notation does not take into account the pawn's initial move? Shouldn't the notation then be written completely as follows: ifmnDfmWcFscW ?


H. G. Muller wrote on Tue, Aug 8, 2023 12:09 PM UTC in reply to Gerd Degens from 11:59 AM:

That is of course up to you. But it is usually more productive to start with the thing that is ~100 times easier. I don't think you would be asking help here in that case...


💡📝Gerd Degens wrote on Tue, Aug 8, 2023 11:59 AM UTC in reply to H. G. Muller from 10:31 AM:

Hadn't worked with either Game Courier or Play-Test Applet so far. I have started with Game Courier and would like to start with Play-Test Applet afterwards. I would be happy if it were a little easier to get to grips with.

Surely a GAME code already exists for Standard Chess; where can I find it (maybe a stupid question)? I would then modify the pawn move as you advised - thanks for that.


H. G. Muller wrote on Tue, Aug 8, 2023 10:31 AM UTC in reply to Gerd Degens from 08:14 AM:

Why not just let the Play-Test Applet generate the GAME code? It should be trivial to set up your variant there; you only have to change the move of the Pawn to fmWcFscW.

@Fergus:
I am trying to bring my variant 'Enhanced Pawn Chess' to Game Courier. I have created the preset, which still runs with the include file 'chess2.txt'. Actually, I intended to save this file under the name 'EnhancedPawnChess.txt' and then modify it in the segment 'Pawn Capturing' according to the enhanced rules. But I am not sure if such a procedure is desired.

My real problem, however, is to modify the game code so that it fits my variant. Despite the 'Developer's Guide' and 'How to Enforce Rules in Game Courier' I can't manage - the latter lists the subroutines for white Pawn Mouvment and Pawn Promotion, but how to adapt is the question! I am working on it, but it will take time.

At this point I would be grateful if I could get help in modifying the pawn rule.

I have adapted the description of my variant.
Thanks for the comments.

Indeed, 'enhanced' or 'augmented' describe something that is larger, but unchanging. 'Progressive', on the other hand, implies an ever increasing sequence of values. The number of moves of your Pawns is large, but it does not grow during the game. When you say 'Progressive Pawn' I would imagine a piece that gets more moves every time you move it. E.g. a single capture straight ahead on rank 2, a normal Pawn on rank 3, capture to the 3 forward squares on rank 4, capture diagonally forward or sideways on rank 5, etc.


Bob Greenwade wrote on Sat, Jul 29, 2023 06:26 PM UTC in reply to Gerd Degens from 05:33 PM:

No, that is not what "more moves per turn" means. You just give a choice between more moves, but the player can play only one of those. In Progressive Chess you would be able to move 2, 3, 4, 5, 6, ... different Pawns each turn.

You're way ahead of me there. Instead of two fields, the pawns can now conquer 6 fields. How else would you call the increase "progressive". What is your term?

What H.G. is getting at is that your Pawns can still only conquer 1 of those 6 fields at a time. They're not "Progressive" in the way that he's saying; they're just more powerful. That's why I suggested calling them Power Pawns. Jean-Louis' suggestions of Augmented or Enhanced would work too.


Jean-Louis Cazaux wrote on Sat, Jul 29, 2023 06:17 PM UTC in reply to Gerd Degens from 05:33 PM:

I agree with the previous comments, "progressive" is not the good word here. I would speak about "augmented" or "enhanced" pawns.

Here I do not understand you. 'Obsolete' does not mean 'out of date', but redundant. With my variation, the 'en passant' rule becomes unnecessary.

So people can still capture en passant, in this variant. Because whether it is unnecessary or not is not for you to decide, but up to the player. I would certainly prefer e.p. capture over replacement capture in some positions. In particular when the Pawn that made the double-step was protected on the square it landed on, but would not have been on the e.p. square, I would consider it better to capture it en passant. Whether it is 'necessary' or not to avoid loss of a Pawn can of course be debated.

then exactly your statement happens, namely that the pawn now has 6 possibilities instead of two to capture.

@ Bob:

... Maybe they could be called Power Pawns?

I have little interest in new figures. I am interested in the further development of standard chess - a rather chanceless endeavour.

@ Ben: Thank you for your kind comment.

When you say: 

"Progressive" in variants usually means increasing moves per turn; the title could be confusing.

then exactly your statement happens, namely that the pawn now has 6 possibilities instead of two to capture.

@ H.G.:

What does it mean: "is obsolete"? If you mean "not allowed in this variant", then better say it. Because there are plenty of people that wouldn't see any harm in doing obsolete things...

Here I do not understand you. 'Obsolete' does not mean 'out of date', but redundant. With my variation, the 'en passant' rule becomes unnecessary.
