Re: Winboard and chess variant

The Lance is also treated as a Pawn-like piece, in the sense that it promotes on last rank, resets the ply counter and generates e.p. rights when advancing more than one rank. At least in most variants. (In Spartan Chess it the generation of e.p. rights is suppressed, as this variant has no e.p. ca...

Re: Winboard and chess variant

Turns out that the WinBoard beta version (unlike 4.8) at least already always removed the correct Pawn (the one that last moved). I now uploaded (to http://hgm.nubati.net/WinBoard-AA.zip ) a version that calculates the e.p. square after a Pawn multi-push in a more sensible way (so that for a move t...

Re: Winboard and chess variant

So far so good. And then you press d6 (red) to complete the move. This should then perform the 2-leg move e5xc5-d6. WinBoard does not have 'auto-complete' that executes a move when only a single target square is left for the currently selected piece. Yes after pressing the red D6, the piece at C5 w...

Re: Winboard and chess variant

It should be possible to specify general locust captures through the highlight protocol, however. The method is to initially highlight the capture victim in the color cyan (and forget about the target square). When you then receive a 'put' command for that square, the GUI knows the move entry is no...

Re: Winboard and chess variant

I tell winboad that this variant is fairy and am not using betza as this pawn changes its movement rule depending on the rank. I am just using colorfen to mark target squares depending on where the rank this pawn is located. Basically a pawn but with couple of moves added. What you described is comp...

Winboard and chess variant

I am working on a chess variant where the pawn can also move to west/east of the "to" square from normal double step pawn push. See image 1. Image 1: https://i.imgur.com/S8Sdr1V.png That pawn at D7 can move to D5 (chess double step move) and C5 (variant move). After d7c5, white can capture via E.P. ...

Re: Ending positions

This one is scary but interesting to program as drawish because of big material difference.


Position is a draw.
