Article discussing the concept of Mutators.[All Comments] [Add Comment or Rating]João Neto wrote on 2008-05-26 UTCHi Richard. Thanks for that taxonomic work. The harder part is too make those concepts glue together. How to translate those ideas into types and how to compose those types into a game. joaopedroneto wrote on 2008-05-26 UTCHi Ji! I'm not sure if we would like to see the board as a separate entity from the game pieces. It must be thought over. A board can be seen as a set or lattice of special pieces, that for most games are idle, neutral and non-interactive, but in some games they interact. Some games allow players to move cell boards, or cells can be removed (like in Zertz), or cells act over pieces (like games with different terrains)... João Neto wrote on 2008-05-23 UTCA mutator language must be typed. Not all mutators go with each other. Some mutators deal with turns (like progressive mutators), others deal with pieces (eg, apply [Real] to chess king], and so on... This should ease the job of the programmer as well as the language designer. The Central Squares. 3d chess variant where all three levels share their central squares. (6x6x3, Cells: 100) [All Comments] [Add Comment or Rating]joaopedroneto wrote on 2006-05-05 UTCJoe, you are right about saying that the central sqs are simultaneous on all 3 levels. That's why the knight cannot move up and down on those central sqs. The only moves that the knight can do inside that area is move orthogonally then right/left/up or down: these are the combinations that provide the move range on the diagram. joaopedroneto wrote on 2006-05-04 UTCTo understand the knight move, you must think 3D. The L move of a chess knight can be (a) just orthogonal (eg, vertical then horizontal), (b) orthogonal then up/down, (c) up/down then orthogonal. That's why the knight has a lot more moves than expected. The same happens with the Bishop (they can move diagonally up/down) or the Rook (they can move up/down besides orthogonally) joaopedroneto wrote on 2006-05-03 UTCThe basic idea is that those 3x3 central squares are shared by all board levels, so a piece inside one of those squares can move as if it was in any of those 3 boards. Eg, a Rook in d3 can move as it was in board A, board B or board C. That's why the move capabilities inside the central squares provide much more power to any piece there. Connect Chess. Players win by forming a link between the first and last ranks of the board. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]João Neto wrote on 2006-01-18 UTC[I just saw this question now] Indeed that situation was not specified by the original rules. I would say: (a) if a player forms a friendly link and also an enemy link, he wins; (b) if he forms just an enemy link, he loses. David Pritchard. Death notice.[All Comments] [Add Comment or Rating]João Neto wrote on 2006-01-03 UTCDavid Pritchard's death is a loss (every death is) but his work on chess variants is very much alive and, hopefully, will continue to be fruitful for a long time. I feel that chessvariants.org and its community of users (the only ones that give some meaning to this collection of information) is a remarkable tribute to his previous, pre-internet work, 'the Encyclopedia of Chess Variants'. May our interest be a persistent thank you. Swap Chess. A move can consist of a series of pieces swapping places. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]João Neto wrote on 2006-01-03 UTC>did you consider the basic one-step swap which I described in Switching >Chess? To be honest, I don't remember :-) But I guess not, usually I tend to create faster games that FIDE chess, and by allowing just one move per turn (which might be a swap) my intuition tells me that it would be harder to mate a swapping king (of course, I may be wrong). Anyway, I don't recall ever tried the rules of Switching Chess on my chess ruminations. >I described Switching Chess before I knew of Swap Chess or Balanced Swap >Chess, however, I later found an applet by Ed Friedlander called Swap >Chess 1 that is almost identical to Switching Chess and predated it, >yet it is not attributed to you. I suppose Ed Friedlander read about swap chess here at chessvariants.org. He has applets of other games of mine (like magnetic or capture-the-flag chess). I think that applet implements Balanced Swap Chess. >I guess I am not sure about the originality of Switching Chess vis-a-vis >Swap Chess. This seems a case of convergent invention. The idea is too simple and will probably be 'found' many other times. Eventually, it was already invented before 1998. Cheers, João Neto wrote on 2006-01-03 UTCYour rule seems appropriate. These original rules create too much havoc on the position, and make medium-term strategies difficult to plan. At that time, I start playing a better variant of the same idea: Balanced Swap Chess (http://www.chessvariants.org/diffmove.dir/balancedswap.html). In this variant, the moving ability is much more constrained: only one swap per move. Thanks for your comments! If you like to try a game of balanced swap chess, email me. Abstract Chess. Pieces are represented by stacks of different heights.[All Comments] [Add Comment or Rating]João Neto wrote on 2004-07-22 UTCWell, 14 knights is indeed a powerful army, but takes time to make it. The other player may develop is own pieces in comfortable positions. But that's the spirit of abchess, see the position and reshape your own army accordingly. João Neto wrote on 2004-07-21 UTCThat's a good idea. But it probably would mean that both players would try to keep their queens near an adjacent piece, so they can create a new King while demoting the previous King (if attacked) to a queen and escape the attack. And this tactic could continue in a cycle. Usually, I don't like this type of thing (ie, multiple Kings, demoting royal pieces, ...). Switching Chess. In addition to normal moves, switch with an adjacent friendly piece. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]João Neto wrote on 2004-07-20 UTCEven with Greg's extra rule, I think the game will create many passive positions. You could restrict the switch option to non-royal pieces, so the King could not switch (and so, couldn't easily escape eventual attacks). Also, check Swap Chess (www.chessvariants.com/diffmove.dir/swap.html) as a similar CV concept. Towers Chess. Win by pushing towers to the Kings' squares. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]João Neto wrote on 2004-06-25 UTCI didn't understand the winning condition. How the game ends? If the goal is stated in a sufficient abstract way, this may be a general mutator for games with movement. The Hitchhiker's Guide to Chess - Part II.

Variant on 44 squares with moving cages.[All Comments] [Add Comment or Rating]João Neto wrote on 2004-06-15 UTCThe 1st point (check using a cage insertion) is correct. However, the 2nd point may happen. A pawn inside a cage can be promoted by an insertion. Check the comments in the game webpage. Once again, thanks for your work on the ZRF :-) Slide-Chess. Variant on 44 squares with moving cages. (7x8, Cells: 44) [All Comments] [Add Comment or Rating]João Neto wrote on 2004-06-09 UTCyes, that's right. Inside the cages they are in a non-zone regarding promotions, as the typical place inside most companies :-) João Neto wrote on 2004-06-09 UTCthe pawn can be inside a cage, eg: 8 [O] ( ) 7 . n b k b n r 6 . p p p p p p 5 . . . . . . . 4 . . . . . . . 3 . O O O O O O 2 R N B K B N R 1 a b c d e f g h i now, if that cage is inserted into the board, the pawn will be at the last row and will be promoted. Since the cage may belong to the adversary, it is the mover that decides the promotion, not the owner João Neto wrote on 2004-06-04 UTCHi, indeed Roberto got it right in his ZRF. The idea is that the remaining sliding square should not be at the opposite edge (so, it will not go out of bounds). Both sliding squares must be diagonally or orthogonally adjacent to the main 6x7 board. The last pushed square on the 6x7 board can have pieces, except a King. Sorry about the wording, natural language can be though :-) Joao Neto Slide Chess . Variant on 44 squares with moving cages.[All Comments] [Add Comment or Rating]João Neto wrote on 2004-05-16 UTCHi Antoine I wish to thank you to implement Slide Chess. One problem: Each cage begins on the last player row, you must switch cages in the setup (this is to avoid direct attacks to the enemy tower) The Central Squares. 3d chess variant where all three levels share their central squares. (6x6x3, Cells: 100) [All Comments] [Add Comment or Rating]João Neto wrote on 2003-03-20 UTCI made that game a long time ago (2-3 years) but I think that you could have a Queen just if you promote a pawn. In the setup, the Queen is too powerful on such small board. 21 comments displayedLater ⇩Reverse Order⇧ EarlierPermalink to the exact comments currently displayed.
