Any GUI that can handle this? Hexagon chess board

[gbtami]

Hexagonal chess was rather popular in Eastern Europe before. I find this in my father legacy:

Kool! Appreciate the pics.

I once considered making it an option in WinBoard to offset subsequent ranks by 0.5 square horizontally. That would basically create a hexagonal topology, which could laso be useful for games like Hex and Havanna. It would not have the fancy hexagons, but of course you could suppress the grid lines, and use a board texture with hexagons drawn on them.

But I never got to do a Havanna engine, so it is still on the back burner...

Your father seemed to have been a very intelligent man who thought analytically, can you share some more stories of him? We'll all be very willing to listen.

yes, I would be interested in this also.

Hello,

Hexodus Chess by Gregorz Sidorowicz (from the year 1999)

On Windows 7 Home Edition 32-bit runs this application:
http://www.old-games.com/download/5300/hexodus-chess

There is another download-link available on the website http://www.armageddonchess.com/download.htm , but this software does not execute moves (after extraction the .rar-file) on my system.

Best wishes,
Norbert

I once considered making it an option in WinBoard to offset subsequent ranks by 0.5 square horizontally.

Is that really necessary? I think with a 9x9 board you just have to rotate the board 45 degrees and cut off edge triangles on each side. You also have to redefine how the pieces move; a king can move to any adjacent square except horizontally to the left or right. It won't look very nice, though.

I would not call that any simpler than just offsetting the ranks horizontally (or files vertically). Which is indeed topologically very similar to rotating the board 45 degrees, as then also the horizontal rows of squares (formerly diagonals) are falling just in between each other. But they would be too close, for one, at a distance of 1/sqrt(2) = 0.7 times the distance between cells on the same row. For horizontally offsetted ranks that distance is to large, but by a much smaller factor (sqrt(1.25) = 1.12).

Of course the aspect ratio of cells could also be made subject to an option; Shogi boards do not have square cells, so Shogi users would welcome that!

It's simpler in that I think Winboard supports the game now. Making it look nice is harder.
