Yes indeed, if I update this page I wish to keep the diagram too, it's very nice to have it. Thanks

OK, I see. But the Diagram is intended as a means for practicing the variant that people have just read the rules of in the article, so I think it would be bad to surprise them with other rules. If you manage to correct the article, I will adapt the Diagram accordingly. Of course it would be better if you included the Diagram in the main page of the article; then it will not be pushed into oblivion by later discussions like this one. And then you can correct the Prince move yourself.

Exact HG, I had not realized that. This is the consequence of the fact that I can't edit this page like I do with my other games. (I have the same problem with Shako).

This page on our site is not updated. The updated page is here http://history.chess.free.fr/tamerlane2.htm

If I could I would update the page on CVP too. I could then explain why this evolution.

I was looking to this Interactive Diagram (thanks HG). The Prince's move is not correct. It is not K. It should be KimfnD.

The description in the page says K, so that is what I use in the Diagram.

A very old variant of mine. King can switch only with Prince, so unpromoted, not with Queen. So the player has to decide if he promotes his Prince or not.

Is the King permitted to switch places with a Queen or only with an unpromoted Prince?

If you're into quirky variants, you'll love this one. Just get a load of the ship piece type, for instance.

There's a problem with the King swapping move. It just gets rid of the Prince instead of switching with it.

Tamerlane II

This variant was a submission for the large-variant contest. It is the subject of this weeks interactive diagram.

This variant has some funny rules that required special attention. One was promotion: not only Pawns promote, but a Prince reaching last rank can optionally promote to Queen too. And a Ship can promote to Griffon in the last-rank corners. This was handled by defining Prince as first piece, and specifying only one promoting piece, with as only choices Prince and Queen. This invokes the normal promotion procedure for Princes, letting the user select from the legend table.

Pawn and Ship make use of the user-supplied JavaScript function WeirdPromotion. This automatically promotes these pieces when they reach their respective zones, as in this cases there is no promotion choice.

Another unusual feature of this variant is that, when checkmated, Kings can swapped with Princes,wherever these are located. To make the diagram indicate this possibility, the King was equipped with a universal-leaper move U. The modality 'x', which was already introduced on non-final legs of multi-leg moves to indicate relaying of powers, is now used for indicating such a piece swap with a friendly piece on final (or only) legs.

Adding a plain xU to the King moves would allow it to be swapped with any friendly piece, however. To single out the Princes, we declared the board to be zonal by providing a JavaScript function BadZone. This function tests the the target location for containing a piece of the same color as the mover, and declares the to-square invalid if a non-Prince if found.

As you have Queens as promotees but not in the array, another possibility could be a win by marriage, as in Doug Chatham's Bachelor Chess and my own Bachelor Kamil.
