I like very much tape chess, especially the variant played on a circular shape tape. It's a pity that there's no Game Courier preset for Tape chess. So far I've played only with Zillions. I like simple and clear games, just as this one is.

Very nice game. I like the idea of a non-cubic 3D chess variant.

Ultima. Game where each type of piece has a different capturing ability. (8x8, Cells: 64) (Recognized!)[All Comments] [Add Comment or Rating]

Every game should be played by people that master the rules in order to
reach a theoretical depth. It's not serious to have discussion on rules -
this doesn't serve any purpose.

It's impossible to find some real game theory on Ultima in the Internet.
How about having it here, at the chessvariants pages? If there are any
experienced players around, perphaps they would like to gather
observations just in one place?

Rococo. A clear, aggressive Ultima variant on a 10x10 ring board. (10x10, Cells: 100) (Recognized!)[All Comments] [Add Comment or Rating]

Hi! I was exploring Rococo's ZRF, I found many divergences between what I
was expected to be correct and what does Zillions do.
Now I have many questions to any one concerned with Rococo:
1) wether the Chameleon could swap with the Swapper, jumping over any Long
leaper;
2) wether the Chameleon could swap and capture any Withdrawer or
Advancer;
3) wether a Pawn that's already on the 9th rank could promote by moving
sidewards (it's clear it could not go to the 10th rank);
4) wether a piece on the outer ring could 'commit suicide' (i.e. - does
this count as capturing?).

I will appreciate having authors' opinion.

Thanks a lot.

Cleopatra Chess. No captures, but your Cleopatra (Queen) can seduce opposing pieces to your side. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

I played this game with a human opponent as well as against the computer. I find it to be excellent for fun, probably not perfectly balanced but what game is perfectly balanced, after all?

However, sometimes the game gets stucked: it is possible to block both Cleopatras in such a way no one can win. I suggest the following change to the rules: if for N moves no piece is flipped, the game is drawn. This rule is alike of Chess rule about no pawn move in 50 moves. For Cleopatra chess I think 50 is too much. 10 or 20 should be a good idea.
