I switched back to using Noto Sans for headings on the main site, though I will use Courier Prime for headings in Game Courier for thematic reasons. I could not find any good substitute for Noto Sans among sans serif fonts. I wanted one that put bars on the capital I, and there were few of those. I tried out IBM Plex Sans, but it didn't look as good. I figured out how to keep letters in Noto Sans from touching the horizontal rule by using some bottom padding. Since I'm no longer using small-caps or underlining and overlining, H5 and H6 no longer look as bad as they used to when I was trying out Noto Sans. With these problems taken care of, I figured it was okay to go back to Noto Sans.

HG,

How do I make Xboard display it?

I made some fixes to the diagram. The SAN parser (used when you paste a game into the diagram) choked on moves with a Shogi-style piece id +L, because it tried to handle Shogi promotion suffixes and matching the piece id in the wrong order. It coulld also not understand Chess-style promotion sufixes with Shogi piece names ("=+L"), and unfortunately this is how the SAN generator wrote Shogi promotions. I now altered the latter to just append a + when the promoOffset diagram parameter is defined as non-zero, and the difference beween the promotion piece and the oriinal piece is equal to it. And the parser now understands the + suffix as promotion when promoOffset is non-zero. (Otherwise it inores it, assuming it means 'check'.)

I also made a small improvement to the AI; this searches novel moves deeper than moves that already were possible for the same player in his previous turn. But it has to know the previous two half-moves to determine whether moves are new, and in the root this was not the case. I now let it remember the previous move it played, for that purpose. As a consequence it will now consumate mate-in-1 threats it created with its previous move even on the lowest (2-ply) setting.

I also added a kludge to combat repetition: moves with the same piece as before now are discouraged by a light penalty, and when the move goes back to the square it came from (and nothing was captured with these two moves), it will be penalized with 1/4 of its advantage (if it has any).

these huge, bold, double-underlined headings look absolutely horrible.

Wavy underlines, which I already tried out, look much worse.

Please change it back.

It's important to distinguish each heading level by a different visual style. I am now trying out a style used on Wikipedia for H2. It puts a full-width line underneath the heading. I have done this with the bottom border. So, the line no longer gets broken up by characters with descenders.

I'd like to playtest a variant of this where one of the boards is mirrored. So capturing an enemy piece on one board would eliminate a friendly piece on the other.

I have to say, I think these huge, bold, double-underlined headings look absolutely horrible. Please change it back. Or, at a minimum, get rid of the underlines.

These submission rules do get tedious when playing OTB with a moderator - however, when the moderator is an online software, this variant should be pretty straightforward to implement, play, and develop theory in.

It might feel more natural to allow players to stay in check as they can in Fog of War chess, denying them some protection against direct threats to their King.

Alternative names: Premove chess, Delay chess, Field report chess. The last name imagines the players as generals, who only receive information about their battles periodically, and have to give commands in advance.

One thing to note is that both players can think about their move simultaneously, as they will know their opponent's last move as soon as they make their own. This might necessitate a more precise definition of the clock.

I remember doing this in 2016 with an early apothecary chess.

OK thanks. The problem was that the improvised way in which the UI passed the moves to the AI only worked correctly for Pawn moves (fD or fA). It always passed only a single e.p. square, and if a forward step was made, this was rounded to the square of origin. On sideway orthogonal moves it even crashed the code through division by 0.

This should be fixed now. (Refresh browser cache!)

I am still not entirely happy with it, as when you pass through a check by a non-Pawn it doesn't actually perform the winning capture, but just continues with another move. So while playing you have to be careful not to make illegal moves with the royal Queens. Fortunately the UI will always gray out those. I will try to fix that later.

The off-site image on this page looks like it was made with Game Courier or the Diagram Designer, and it could easily be replaced with a query string link provided by the Diagram Designer.

I adjusted the margins of the headings to be the same, and I put more space above a heading than below it so that each heading is closer to the text it is a heading for. But I also avoided making it look crowded by putting a heading too close to the text following it.
