@Adam: if it helps, look and edit the gc preset of Maasai chess. You will see this set

Yes yes, excellentes fêtes à tous, tantissimi auguri a tutti, very happy season's feasts to all, muy buenas fiestas a todos, tre bonaj ferioj al cxiuj. You are a great community. Take care of you and your beloved ones.

It is me who says you many thanks!

Thank you very much. It looks like a well though model. It makes a lot of sense.

I understand that the random positions are taken on the related board, so the result is indeed dependent of its dimensions (which is expected I guess).

That randomisation at the beginning explains why I get different results by re-doing the operation. For example with a Rook's value normalised at 5, on a regular 64-sq chessboard, I get Queen as 8.95; 9.2; 9.6; 9.8 on 4 consecutive trials.

I agree that this enough to what it is done for. I wonder if increasing the number of 10 positions would decrease the results' span.

Thank you again for this detailed explanation

I knew that Heavy Chess was far from being original, being strongly inspired by Sac Chess. But yesterday I realised that Kevin Pacey had even proposed exactly the same variant several years ago under the name of Royal Bevy Chess.

Therefore, I feel sorry and I have modified the text of this page to better credit him.

@HG: why the "estimated piece values" are varying when I reload the page. Even relatively one piece to another, I see some changes.

Is the way it is estimated explained somewhere?

Thank you

I like very much the concept behind this game. I'm eager to play it to see how it goes.

I use "Alfaerie for Metamachy" as a set for the GC presets of my CVs. Who could add 6 new pieces from Alfaerie , coded with 2 letters, to this set?

I would like to have added: the Snake (SN), the Ship (SH), the Bird (BI), the Tiger (TI), the Ram (RA), the Dragon (DR).

Thanks for the help.

@Adam: thank you, I had copied what was done for SAC chess, i thought that 4 parameters were necessary indicating both K and R moves. But you're right, it is not the case. I don't know if it may induce an error as it is, I don't find any case.

@Greg: according to the point above, the presets to be corrected are SAC chess, Heavy Chess and Very Heavy Chess. Thank you.

As a matter of fact, I had had only a minor contribution in support of Eric Silverman and I cannot be considered as a co-author. Just "inspirator" if I may say.

I have myself designed and published a similar CV which aim is indeed to complement Shako, it is Pemba, https://www.chessvariants.com/rules/pemba

In addition if you want to make the lineage with my games, it would be important to respect the choice of names and icons I've made for them and that I use in all my games. This matters a lot for me. Eric S has respected this in the Heavy Shako he made available on AI AI.

You could use the "alfaerie for Metamachy" set for that, it has them all.

Your Zebra (which plays AND and not Z) should be a Squirrel, Your Castle (WD) should be a (modern) War Machine, Your small queen (=Leo) should be a Sorceress, represented by a star, Your Lance should be a Crocodile (=Vao), Your Unicorn should be a Buffalo (NCZ).

Thank you

Thanks a lot

@Adam: thank you for the explanation.

I have then submitted the GC Preset for Hannibal Chess with moves displayed and enforced rules.

I was forced to mention this is the title because a short "Hannibal Chess" exists already, it is a preset with no rules enforced. I hope this doesn't cause any problem.

For what concerns Very Heavy Chess, any answer ? Again the available preset is bugged. Shall I update also a corrected version? If I do that someone will remove the bugged one?

Excellent! Thank you very much

Hello.I fear nobody will answer my last posts here, so I renew in case I'll have more success:

• There is a bug in the GC preset of Very Heavy Chess available from the Alphabetical index. I have given the reason in my earlier message and suggest what has to be modified. Can someone make the correction?

• I have made a GC preset for Hannibal Chess. It is available under my own GC Setting Files. How to place it in the list of "Games to play" and/or the Alphabetical index?

Of course I will do that myself if someone explains me how to do.

Thank you

Thanks HG.

"I hope you agree that it hardly matters for the intuitive understanding whether one would write F&R, F-R, [F-R] or [F,R]. " >> Yes,of course;

"With W[F-R] there is little doubt that the W is a separate move" >> I fully agree

"And how would you know that in N&$R 'outward' would mean 'in the direction of the long component'? " >> Not sure what you mean by long. The "R" part? I don't see what the problem is, it is not easy by messages. "Outward" for me means the move is always in the direction of going away from the starting square both in x and y. If after the first leg, the second leg starts by going to a square that is closer to starting square either in x or y than the intermediate square (between the two legs), then it is not outward on that definition.

"Is F&fR really any less intuitive than F&$R ?" >> no no it is not. Don't misunderstand me.I was just using these 2 characters & and $ just for the example and to avoid to select 2 true letters and thus choose the wrong ones. You can replace them by any letter or character.

" I think it would be a mistake to judge a description system solely on how well it does on a single piece that you happen to use, but is not very common, and even less representative for the general problem" >> I fully agree. This is a must.

"how can we describe the Mao then?" >> Again I agree with you, I don't know.

I was not proposing a new system, I was just trying to answer your question to me by making a thought to fuel the discussion, but of course I don't pretend to have solve this very difficult issue. I do rely on you and other skilled people in that matter.

I also have the feeling that maybe it would necessary to introduce more symbols.

I have the feeling that this page is not the latest version. I was looking for an information that I'm almost sure was there and now I see this page which seems not updated. Same thing with the "editors" page. Am I wrong?

A small detail: this article uses the word "heterdox" many times, except once it uses "heterodox". Is "heterdox" an English word valid in this context or just a typo here?

I have written a preset to play Hannibal Chess, enforcing the rules, which is therefore better than the one available. We are playing it with Kevin P.

My preset is here:

https://www.chessvariants.com/play/pbm/play.php?game=Hannibal+Chess&settings=default-v2

I don't know how to made it available for the Games menu. Maybe an editor can do it?

Thank you

Bright! Thank you

@Greg or another editor.

I think I know where the bug comes from in the Very Heavy Chess preset.

The "Pre-Game" block doesn't have the right squares, it has been cut-and-paste from Heavy Chess.

Instead of

setflag b2 b9 i2 i9 f2 f9; set k f9; set K f2; set ep false; set bpr 8; set wpr 3; set wcastle d2 e2 g2 h2; set bcastle d9 e9 g9 h9;

it should be:

setflag c2 c9 j2 j9 g2 g9; set k g9; set K g2; set ep false; set bpr 8; set wpr 3; set wcastle e2 f2 h2 i2; set bcastle e9 f9 h9 i9;

Could you make the correction?

Also the "Rules URL" is wrong, pointing to Heavy Chess instead of Very Heavy Chess.

I could do the correction myself but I don't think it will be saved for everyone.

Thank you

I'm impressed by this development. But it is complex for me to understand, despite of the very clear text, it is not intuitive for me. I'm particularly interested by bent riders. A Gryphon without W or R in the string is strange, I understand the explanation but it is too bad there is no a modifier to say "move outwards as X". I'm not at all a computer language expert, I confess.

I got the string for the Gryphon, I can derive the one for Manticore by replacing the F by W. I think this is right. But I failed in fiding the string for the Ship (an half-Gryphon, only sliding vertically, not horizontally) and the Snake(tongue) (an half-Manticore, 1 step v then sliding diag away, never 1 step h then diag). What is the solution?

Thanks a lot
