 By H. G.  Muller. Veteran Chess. Most pieces can or must irreveribly promote when they capture.[All Comments] [Add Comment or Rating]
H. G. Muller wrote on 2019-10-18 UTC

Alfaerie is one of the six preconfigured settings in the design wizard for the interactive diagram, (setting the right values for the image directory, square size, white/black prefix and graphics type at the press of a button), and in fact the default choice. Other buttons give you Abstract, Motif, Utrecht, 2 sizes XBoard presets. And of course you could use your own uploaded graphics, by supplying the location and other parameters to the design wizard explicitly.

For the pieces I needed Alfaerie was not too bad. I had to improvise a bit for the (Mounted) Veteran, using the Wazir(-Knight) instead, thus only indicating the non-capture move correctly. But that seemed acceptible.

Some of the other Alfaerie pieces look embarrasingly simplistic (e.g. Elephant), so I usually prefer the XBoard theme when I need any of those. Even the orthodox pieces look pretty ugly in Alfaerie; they are not anti-aliased, giving them a very ragged appearance. This is so 20th-century... I think it is high time someone would take the trouble replacing all the Alfaerie image files by anti-aliased versions (with alpha channel).

versus  

BTW, I am happy you like Veteran Chess. I have not programmed it into any engine yet, but I play-tested it against a regular participant of the Dutch Superchess championship over the board, and it seemed quite playable. That 1:1 trading is discouraged by leaving the opponent with a promoted piece seems compensated well enough by that in 2:1 trading you can promote your second piece to compensate for the loss of the first. E.g. a Pawn protected by a Pawn is pretty much unassailable in orthodox Chess, but here after BxP, PxP, NxP=M promoting the Knight to a Rook-class piece plus capture of two Pawns seems enough compensation for the Bishop. So you don't get into stand-off situations too easily.

A very interesting game.  And you have the interactive diagram using our signature Alfaerie pieces and colors!  I love it :)

I still have an old price list, and George Hodges did not make a Taikyoku Shogi set.

As an opposing army for orthodox Chess this seems way too strong. A leaper with 16 targets typically is worth about 7 Pawns, and with 24 targets about 11 Pawns. Together with the Sages, which are about Knight value, this already balances the fide army. But in addition you have the two Flying Jesters, which are major pieces, and should be worth at least a Knight, and more likely about 4 Pawns each.

So pitting this against fide is like being Rook + minor ahead...

Yes, graphics are present now, and I've unhidden the page.

You might consider renaming the Chimera Rider, since "rider" is a common variant piece descriptor.

Dear Fergus,

I am the inventor of Chimera chess who posted the description above.

I had a look at the page from my account, and I can see all the images.

Could you please check again? 

 

Thanks,

Kevin Pacey wrote on 2019-09-29 UTC

Today I've had an idea for a CV that might be called 'Accelerated Courier-Spiel'. The thought is to try to come up with a modified version of Courier-Spiel that one day just might be significantly more popular with modern day chess (and CV) players.

The rules would be the same as for Courier-Spiel, except:

1) Some form of fast-castling rules would be used - in particular such as those used for my own 'Wide Chess' CV:

https://www.chessvariants.com/rules/wide-chess

2) The 'fool' pieces (move like guards) would be replaced by Archbishops, in the setup.

3) The pawns would behave as in standard chess, except that they can promote to any piece type in the (modified) setup, except for a king.

Note I thought about somehow having Chancellors in the setup, too, but given that I wanted 12 non-pawn pieces per side still, I didn't mind excluding Chancellors as I've always worried they might trade each other off too easily in CVs where they can be developed to be able to do so in just one more move, if either player is willing or has no better option.

The diagrams need some work (they have various additional markers?), and you don't need to include diagrams for FIDE pieces.

Nice one Ben, exactly right.  In addition:

Pushing the King to d5 also works, but my original idea- just like your line of thinking, was "return to the square it just left" like in my checkmate example in the Pieces section. Even though it can do a lot, I'm pretty sure the sentry is still just a bit weaker than a bishop (and that's how I wanted it), for example if the sentry were a pinned piece here, it can't perform the final mate move, while a bishop already has it mated. Advantages and disadvantages is what I was going for.

Thanks H.G., I've changed my older comment to use the inline-style whiteout.


H. G. Muller wrote on 2019-09-20 UTC

A common work-around for spoilers is to print them as white text on a white background. Selecting it then usually makes it visible. This editor doesn't seem to have a button for selection of the font color, though. But of course this could be done through HTML tags. Like below:

This sentence is printed in white.


Ben Reiniger wrote on 2019-09-20 UTC

I've put (what I think is) the solution in my last comment, but as an html comment.  You can see it by viewing the page's source code (ctrl+u on most browsers; then ctrl+f to search for "spoiler" should get you there quickly).  I was suggesting/asking whether we (the editors) should pursue adding a spoiler-hiding method and, probably, a button in CKEditor to insert such a spoiler to the site.


Jeffrey T. Kubach wrote on 2019-09-19 UTC

You’re asking the admin team for Spoiler text as a feature?  Or did you want me to simply post the sequence for now?


Ben Reiniger wrote on 2019-09-19 UTC

Spoiler(?) (should we consider adding a spoiler tag plugin for CKEditor?):

Qxc5+, ke6 // in check both from queen and sentry->lancer
Qd5+, ke7
Qxf7+, kd6 // again doubly checked
Ld2=n+, kc6
S-c6Kd6# // checked by Lancer, no piece to interject; cannot move back to Sentry's square, and Queen and Pawns cover last escape squares.

H. G. Muller wrote on 2019-09-19 UTC

Currently the diagram is limited to a single locust capture. Which already makes the Lion Dog of the large Shogi variants fall beyond its capabilities. If this were solved (e.g. by allowing an array of locust-victim coordinates), the XBetza notation could specify each number of victims separately, e.g. RcdafRcdafcdafR ... Which for a big board like Taikyoku's 36x36 becomes of course very cumbersome.

Perhaps there would be some benefit of extending XBetza notation with a 'repeat count' on a group of modifiers. This would then replace the 'a' modifier. A leading '0' on the number could indicate 'exactly that many', where otherwise it would mean up to that number. So cd02fR would then mean cdafcdafR. Where the expansion rule is that the repeat count would group with preceding modality modifiers, and following directional modifiers. (So that you could still slam an initial directional modifier on the first leg, and a different modality modifier on the last one. That would allow description of the Tenjiku jumping generals as multi-hoppers: Rp14cR or Rp0cR.)


Adam DeWitt wrote on 2019-09-19 UTC

I wonder if there is a way to make a piece capture everything in its path? For example, in Taikyoku Shogi there are range-capturing pieces that destroy everything in their path (including friendly pieces). In Betza 2.0 this behavior could be indicated using cd0. Perhaps the WeirdChain function holds the answer?

On my Linux system on an Intel PC I never had any such problems with XBoard + Fairy-Max. Which is the essential change that finally made it work for you? The fflush(stdin)?


x-board user wrote on 2019-09-17 UTC

I use fairymax all the time, since I'm not a great player, but it's challenging enough that it's still hard to beat.  Unfortunately, it seemed to block indefinitely while talking to X-board.  I was curious what was happening since I'm interested in chess engines.  There is a large section on stream blocking, etc on the X-board site. I managed to fix the problem, and happy to report it played gnu-chess in a game on an ARM chromebook computer running the latest linux OS.

I pasted the resulting code here:

Not sure this is the right place for my comment, as it may apply much more to Game Courier than Chess. Anyway, I was trying to use the Record feature for the chess preset. I entered 1.e2-e4 1.e7-e5 2.f1-c4 b8-c6 3.d1-f3 c6-d4 4.f3-f7 successfully (a version of Scholar's mate trap). However, when I tried to do the same thing but also insert "| 3.g8-f6 //is a better move." after Black's 3rd move, I got an error message saying I cannot move my opponent's piece, after I clicked on the 'View' button (that is, I unsuccessfully tried to enter a variation plus comment after the 3rd Black move of the main continuation).

I'm wondering if Game Courier's Record feature isn't fully working properly. In any event, I've yet to see a single webpage on CVP where a recorded game(s) have been offered by the author, and maybe that's no coincidence. [edit: I had missed the example game using the Record feature on the Voidrider CVP webpage. The moves were given, although no variations were offered (just Comments here and there), but more importantly, perhaps, I couldn't view a board from the Voidrider page for the example game.]
