The short story is that black has just captured an chancellor on h10 and white is to move. The version that I have (I think is the last one published) gives now a stalemate. The long story is that any piece moved by white leads to a king capture by black in the next move. Here actually the black chancellor on e2 has a role to play. The difference from the studies we already have is that a role is played by the white joker who inherits and transmits a king (more actually a man I think) power. Is that in the second case a checkmate or a stalemate? It looks like ChessV as white has sacrificed it's chancellor for an easy draw, but is this a way for black to checkmate the opponent? And most important how should it be? I am confused by this myself. Depending on what you can do Greg, I am ready to adjust the rules in these rare cases. The most important thing is though, that the rules are clear for everybody.
And c is a chancellor, but this actually has no importance!

The fen of the position, as is found in chessV, is this:
3J3k1w/10/10/8p1/2P5Pp/1S7P/5s4/10/4c4j/7BK1 w - - 0 78
but I did not manage to do it. Here J stands for joker, w stands for wizard, s stands for maasai pawn. The rest are self explanatory.

For a static image that should be good enough. You can also use the Interactive Diagram as a game viewer, by including a parameter moveList= , followed by all the moves of the game. This preloads the game in the Diagram, and you can then use the buttons in the AI panel to navigate through it.
Oklh, that is using the diagram designer, isn't it?

I think I have encountered a new situation involving the joker. I want to post a png with the position but I don't know how. Can someone tell me how to add a picure in the comments?

Chess 1010. Game played with 40 pieces. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]DIAGRAM WITH REDUNDANT ROOKS
Here's an alternate setup, similar to TenCubed Chess. The Archbishop (e1) defends the Knight (c2) which protects a Pawn (a3) and a Rook (a1). After the Knight has moved, the Archbishop may take its place on (c2). The Chancellor has much the same story. Note that the Queens are now on their own colors. My personal preference is placing the Rooks on the second rank and something exotic - like Cannons - in the corners. With your Rooks in the corners, you are free to try new pieces on (b2) and (i2). Silver Generals would provide a rock solid defence of the Pawns - perhaps too solid.
[EDIT] This arrangement of four Rooks was actually used in Colossus - Charles Daniel (2010).

This Diagram lets the Queen burn both actively and passively. It uses trackPieces=1 to track the Queen, so WeirdPromotion() can efficiently get her location, and mark the adjacent squares as the burn zone, to destroy all pieces that land there.
(Refresh the browser cache, as there was a bug in the standard script w.r.t. kamikaze moves: these did set the 'non-virgin' flag on the resulting empty square, so the Diagram would treat it as an invisible white piece rather than an empty square. For now I solved that by making all pieces resulting from promotion virgin. Which is of course incorrect, but much less harmful.)

Afaict the second part of the N's move is optional here, so it may make one‐step orthogonal moves and thus access the central square if needed. So it's more a Rhino than a traditional Knight
Home page of The Chess Variant Pages. Homepage of The Chess Variant Pages.[All Comments] [Add Comment or Rating]Yes, I was thinking that we no longer need the quickedit script. It was made back when I was still accessing the site through dial-up. Now that we're all using broadband, dial-up speeds are no longer a bottleneck. Besides that, I have since reduced the size of the edititem script by replacing four separate but identical drop-down lists with a single datalist that gets used by four different fields.

Tenjiku Shogi. Fire Demons burn surrounding enemies, Generals capture jumping many pieces. (16x16, Cells: 256) [All Comments] [Add Comment or Rating]📝H. G. Muller wrote on Sun, Jan 29, 2023 10:38 AM UTC in reply to A. M. DeWitt from Sat Jan 28 09:36 PM:Indeed, a user promotion choice does overrule everything else. If a fixed promotion is required for pieces that would offer choice, the promotion query should be suppressed. Not only because it would prevail, but because it makes no sense at all to let the user choose and then do something else.
The mechanism the Diagram uses for this is to call WeirdPromotion() with the promo parameter set to 1021 (which is not a valid piece type), to inquire whether there is promotion choice. When this call returns 1001 the query will be suppressed, when it returns 1000 a query is forced, and in any other case it decides itself (based on maxPromote, promoZone and promoChoice).
In the AI it works slightly different; there (for a piece that could normally promote) WeirdPromotion() is called with promo equal to the promoted piece (as per promoOffset), and to suppress the promotion this would have to return 1022. It is the deferral (promo=0) that must be turned into a kamikaze move by returning 251, so that moves that would not naturally promote also get burned.
So when a passive burn is detected, WeirdPromotion() should return 1001 if promo == 1021, 251 if promo == 0 and 1022 otherwise.

Muller wrote on Sun, Jan 29, 2023 10:07 AM UTC:"This rule gets rid of zugzwang." More than sixty years ago I learned how to use zugzwang to win with King and Rook against the lone King. So how does Tony Berard deal with this problem? "The rooks, bishops, and knights now also move and capture like a king." Sixteen years ago I commented on Ultra Chess (by Ruggero Micheletto). Here is a question for both authors. Is the endgame King and Rook versus King and Knight even more likely to lead to a draw in your chess variants?

But it does look like I may have been wrong about the title: the domains are each infinite, while apparently the domains are supposed to be limited to an 8x8 grid.

Again, I really think allowing nulls for non-game items would be best, and BoardRealms should be defaulted to 1 in any forms.

Ok, diagram updated with Chancellor.
What was White's last move? The version you have doesn't have the updated rules yet, so the black joker can't move. In the updated version, the black joker will have the ability of white's last move, which could make it a checkmate if it attacks the white king. Otherwise, it is still a stalemate under the new rules. Any piece white moves would lead to white's king being in check by the black joker. Even white moving joker (imitating a king) would make black's joker imitate a king and therefore it is still check. Since white cannot move, it's a stalemate.
