Re: Classes of chess pieces for chess variants

BTW, just out of curiosity: you say you also want to include other Musketeer Pieces. But some of those (e.g. Cannon) are not fully 8-fold symmetric. They have moves in some directions, but not in other symmetry-equivalent directions. But directions are not a well-defined concept on your CirSquare b...

Re: Classes of chess pieces for chess variants

What is wrong with this , then? I was referring to the jocly website (probably jocly.com) that was destroyed by hackers and there are evidently no plans to rebuild it. Apparently, some of the jocly developers have partially brought it back on GitHub. I followed your link, which opened the Jocly ver...

Re: Classes of chess pieces for chess variants

Indeed, that is what almost anyone expects. And it is totally wrong. In reality Archbishop beats Rook + Knight (two separate pieces) more often than not, on 8x8 or 10x8. Certainly from an opening position, but also in an end-game where these are the only pieces (apart from sufficiently many Pawns)....

Re: Classes of chess pieces for chess variants

This method is sound, but not using Zillion's values, for the reasons H.G.M. mentioned. The values that Zillions gives to pieces depend on how you code them, and you can arbitrarily increase their value by using different code. What you'd end up with is pieces that are very undervalued and others t...

Re: Classes of chess pieces for chess variants

Thanks HGM. My Action cards give a piece an enhanced move (one that it normally cannot do) for one turn only. Here are some examples: With a Class 4 Piece that can leap, make 2 or 3 normal moves from its current position anywhere on the board to an open space. Cannot capture, but may place the King ...

I need help/advise/suggestions establishing classes of chess pieces for chess variants that use action cards to incorporate special moves or circumstances for a chess variant turn. My chess variant Thrones Chess V (aka Castle Challenge Chess) uses 70+ Action cards. it also uses a chess board (called...

Re: best server for computers to play variants currently?

Does anyone know of a chess engine that can be used for a chess variant that uses a circular board? My game, Castle Siege Chess, uses a board that merges a 6x6 square board into the center of a circular board. I have previously used Zillions of Games script to program it with high success, but Zilli...

Re: Chess engines for circular chess boards

Evert, I just edited the ZoG script for CSC to make the A and C capture on the 3rd space instead of the 2nd space. It made virtually no difference in their power rating. But I can't help but feel like they would be more dangerous by being able to strike from one square further away from the target. ...

Re: Chess engines for circular chess boards

Evert, Based on your earlier response which included a discussion on the relative power of the Archer and Catapult based a few different types of calculations, I rooted around in Zillions of Games and discovered that it too has a power rating system for game pieces. It uses numbers that are in the t...
