@Fergus,

I still need to understand how to delete a value from an array in order to remove the necessary value from wcastle or bcastle.

I still need to understand how to delete a value from an array in order to remove the necessary value from wcastle or bcastle.

You can unset an array element if you know its key. For example:

set ra array a b c d e f g h i j k l m n o p q r;
unset ra.4; // removes e from array

But what if you just know the element you want to delete and not its key? I have now added a diff operator to return an array difference. When an argument isn't already an array, it gets turned into a single element array. So, this code removes j1 from wcastle.

set wcastle d1 c1 j1 k1;
set wcastle diff #wcastle j1;

Thank you, Fergus!

With your piece of code I have tested my idea and made it work as intended. Thanks once again, Fergus!

In wikipedia Fairy chess pieces they are the Osprey for DthenB and the Ostrich for AthenR

@Bn Em I meant a piece that takes the first 2 steps like a rook and then towards outside like a bishop. The osprey jumps as a dabbabah and then moves towards outside like a bishop. So they are not the same piece.

@Jean-louis

Agreed but these are not the pieces I am talking about. I'm saying a piece that starts like a rook for the first 2 steps and then it goes towards outside like a bishop. So this 2. Maticore would be able to stop or be blocked at wazir sqaures.

Hello Aurelian,

Sorry I didn't see that the last round has begun. It's true that my e-mail is not visible. I could have given it to you (or you could have asked me:) at the start of the tournament...

Sorry, I don't play long-term correspondence games anymore. So I resign for my last games and I give the victory to my opponent Daniel. Congratulations for all the participants, and for Aurelian for creating Apothecary Chess! The 3rd round games I play against Daniel were particularly intense from beginning to end.

Here is the relevant rule:

When there are no captured pieces a Cavalier may promote to, it may not move to the last rank, though it may still check the Eques Rex on the last rank.

Is there a violation of this rule?

You already made an Interactive Diagram that does the Pawn move and the castling in the way you want, right? All you have to do is paste the description of that diagram (without any HTML tags) into the Play-Test Applet, (where it says "paste an existing diagram"), and click the 'Game code' button.

1) It seems the checkbox "Do not include moves in code" is not ticked.

2) Something is wrong with the shuffling; I still have to figure out what. When I delete the last line of the Pre-Game code ("gosub ShuffleSetup;") the preset seems to work (but without shuffling, of course).

It's not so much that there is a bug here but that this preset was written before I gave Game Courier the ability to move pieces by clicking with the mouse. So, I did not program it to handle partial moves. As long as you enter the whole move at once, which will require some typing, it will allow the promotion. I will eventually get around to updating this preset or replacing it with a new one.

ok, great.   Thank you.

@Fergus: I don't understand what is wrong with the following GAME code:

  for (sqr, piece) $space:
print . iter . #piece #sqr;
    if match #piece #toshuffle:
      if < * 2 file #sqr lastfile:  // left half
        push left #sqr;
      endif;
      if & 1 + file #sqr rank #sqr: // distinguish by shade
        push dark #sqr;
      else:
        push light #sqr;
      endif;
    endif;
  next;
print "got it";

I would have expected it to loop over the board. But instead it prints "iter0" and then exits. If I do a "printr $space" just before it, it does print the board as expected.

When I tried it by itself, it did loop through the board. Perhaps something in the outer context is affecting your code.
