HaruN Y: I made a couple of moves in the Interactive Diagram while I was tired and failed to notice that you were using four colors for the pieces!!!! Today I found an actual (Rule 1) problem - consistently making an illegal King move towards a distant piece giving check. Below is the record of a 3-ply search after the White Rook checkmates.

1. a3=₱ e5=₱ 2. Ra4=® Nf6=Ñ 3. ®e4=R Ke7=O

Is this better?

What's wrong with 4 colors?

Many thanks for your hard work. Plays the game better than I can now! The Interactive Diagram recognizes all Rook and Courier checkmates by either side. As for my comment regarding four colors --- when I first saw your display, I looked up and realised that my game had been posted with just the tags [2d] and [8x8]. After playing one move for each side, my first thought was that the new colors were being used to indicate the most recent move on an 8x8 board.

O'Donohue Chess by Michael O'Donohue

I tried out the 3-move checkmate with a Rook --- that Interactive Diagram also tries to escape checkmate with Ke7 (Ko7 according to the coordinate system used in that game).

Idk how to fix that, so just pretend that's a feature.

Since all the comments were appearing in boldface, I edited the page to close the last boldface tag.

The name for this game is misleading. I was expecting it to be Courier Chess played by Alice Chess rules, but instead it has two 8x8 boards, and the Courier is actually a Dragon Horse rather than the Courier in Courier Chess. In the piece descriptions, this piece is called a General instead of a Courier.

Maybe replacing the Bishops with more mobile pieces will help in an Alice Chess type game, but replacing the Queens with much less mobile colorbound pieces might have the opposite effect.

The Knight and Jester endgame in the diagram below is interesting for two reasons. First, the corner (h1/H1) is a light square which the Jester can never attack. Second, as long as the opponent's King stays on the first rank, the Knight cannot give check anywhere on either board. But checkmate can still be achieved in only five moves.

1. KG4 KH1 2.Kh3 Kg1 3. NF1 KH1 4. Ng3 Kg1 5. Je3 mate

Note that on a normal 8x8 board Knight + Padwar can also force checkmate in corners of the shade the Padwar is not on: the 'choice mate' described for N + FAD also works for Padwar. With Alice rules you have an extra restriction that the King in the final position is on the board where it is in check, but you have the possibility to prevent the bare King escaping its confinement by blocking it, on a square where you otherwise would be captured by it. The Nf1 manoeuvre is only possible with Alice rules.
