Venomous. New system of chess on 10x10 board with new pieces: the Sorcerer Snake and the even more venomous Sissa. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]
Carlos Cetina wrote on Wed, Jul 1, 2009 07:29 PM UTC:Excellent ★★★★★

I cannot less than celebrate, Charles, your choice of including the sissa in one of your game designs. Excellent!

Certainly, this piece has not been adequately explored in other chess systems. I have had the oportunity of seeing some of its peculiarities on an 8x8 board starting from the randomly positions of my Cetina Random Chess and Cetran Chess 2 proposals.

'Instead of boring the player with arcane references to complex, convoluted, and contrived theoretical jargon,...', as you just say, I would like to show here some samples of THE SISSA IN ACTION!

At the following position White to move:

White moves Sc1+ [moving path: d1-c2-c1 or d1-d2-c1 / checking path: c1-h1-c6]:

At the same time the sissa is menacing the rook by c1-c2-b3 or c1-b2-b3. Obviously if Blue moves his king, would lose his rook. Fortunately Blue has salvation by moving Rf3 that obstructs the h1-c6 diagonal, interrupting, cutting the check:

At the following position Blue to move:

In the real game Blue moved Kd5, but what would happen if he moves c4?...

... White would make Sa5+...

... moving path: b3-a4-a5 / checking path: a5-b5-c6. Notice that the sissa covers both b5 (a5-a6-b5 or a5-a4-b5) and d5 (a5-a8-d5). Blue is losing his pawn on c4, so Kc5 is unique...

But now White makes the surprising and spectacular movement Se5+!

Moving path: a5-a1-e5 / Checking path: e5-c7-c5 or e5-e7-c5 or e5-e3-c5.

The sissa covers
b5 by e5-e8-b5;
c6 by e5-d5-c6 or e5-d6-c6 and
d5 by e5-d6-d5 or e5-d4-d5 or e5-e6-d5 or e5-e4-d5.

Blue has two options: Kd6 and Kd4. If makes Kd6, obviously would lose his pawn on c4. And if he makes Kd4? Let's see it:

Then White wins the rook by moving Sd7+...

...moving path: e5-e6-d7 or e5-d6-d7 / checking path: d7-g7-d4 or d7-g4-d4. The rook is captured by d7-c7-b6 or d7-c6-b6.

Viewing these examples of what the sissa can do on an 8x8 board, we can hope reasonably that on a 10x10 its powerful will be increased greatly, overall by acting in combination with the remain venomous pieces.


Sissa. Move exists of moving a number of squares as rook and an equal number of squares as bishop.[All Comments] [Add Comment or Rating]

Claudio: The 'sub-sissas' you mention are possible.

I'm not sure if you understand sissa's move rightly or not. The direction of the second stage of the movement has no restriction regarding to the first. For instance, let's suppose the sissa is on d1 over a 10x10 board. If we move it first 3 squares like rook to d4, then the second stage NOW LIKE BISHOP can be in any of the four possible directions:

1) 3 steps towards g7, or
2) 3 steps towards a7, or
3) 3 steps towards a1, or
4) 3 steps towards g1.

If, viceversa, we move it first like bishop 3 squares to (say) g4, then the second stage NOW LIKE ROOK can be in any of the four possible directions:

1) 3 steps towards j4, or
2) 3 steps towards g7, or
3) 3 steps towards d4, or
4) 3 steps towards g1.

Hopefully some day you encourage to play a game of Cetran Chess 2 with me. Then you would see with a whole evidence that this piece is a true WONDER OF NATURE!

Receive a bear hug!

I know that all the icons designed by Matthew La Vallee (whose code carry his initial letters: _MLV_) were added to the Alfaerie Many set by Antoine.

Thanks, Rich, for your stimulating words.

Gradually I'll go doing here at this item of the Ratings and Comments Section some precisions and clarifications.

There is a lot of work to do in the particular road that this variant is.

It is a gigantesque challenge to edit UC's presets with a set of pieces formed each time by a larger number of pieces.

I have in mind to add to the UC-73 preset, among others, the following pieces:

1)Maorider Chess's king [when this piece appear on the board, the players would have to checkmate two kings for winning the game];
2)Catapult, Ram, Troy Horse (including the Archer) from Gifford's Catapults of Troy;
3)Jeremy Good's Top Heart and Bottom Heart;
4)the set of pieces of Chu Shogi (alfaerie style), specially the shishi;
5)Mamra and Wuss [when the wuss, the standard FIDE chess king and the Maorider Chess king coincide at the board, the players would have to checkmate to the three for winning the game];
6)some pieces from Ganymede Chess, like Spearman, Minirose, Dragon, Moonrider, Roc, Frog, Fort;
7)the pieces recently designed by Jeremy for Crooked Chess;
8)the Nachtmahr's crooked nightriders;
9)several pieces designed by Charles Daniel, specially the octopus;

I expect help from others to develop a list of pieces (especially exotics) as large as possible.


💡📝Carlos Cetina wrote on Mon, Oct 5, 2009 10:33 PM UTC:

Good question, Nick, that all the interested in UC [a path in the jungle] will have to resolve together. Sure Jeremy, Joe, Vitya and many others have something to say.

My opinion is that not necessarily both kings have to be checkmated at the same time; if one is first checkmated, this would remain on the board like if it were frozen. But also is perfectly possible to introduce a rule that states that if two or three [in case that the Wuss come into the game] kings are in play, then they will have to be captured, not checkmated.

By the way, I think all the Wildest Kingdom Chess' animals [less perhaps the crocodile] may also be part of the UC's set of pieces. These animals (pieces) would come into the game with the ability of use its 'specials'. Then, it might be possible that 4 kings were in the game at the same time, if the lion also appear in the starting setup or it's dropped.

K/k = King

💡📝Carlos Cetina wrote on Sun, Oct 18, 2009 08:58 PM UTC:
I would not miss the opportunity to show an example of how would work pawns promotion in this variant, which would mean a very active role for them in the game.

The following diagram is from a current game between Vitya Makov [White] and me [Blue]. Blue to move. Turn 10.

According to the rules, the first pawn that reaches the opponent's 1st rank will be promoted to the final piece of the dropping order, in this case to queen.

So, if Blue move 10. ... p e2-e1=q+, 11.A f3xe1 is practically forced since otherwise if 11.NE e3-d1 or 11.A f3-d1 or even 11.CBW b1-d1 Blue would take White's dancing horse: 11. ... q e1xg3.

Then, after 11.A f3xe1 l h4xe1 Blue achieves a net profit of one piece, since his lion (cannon/vao) from e1 would capture either the crooked bishop/wazir on b1 or the knight/guard on a1.

Of course, Blue's crooked bishop/wazir on d7 covers c2 by the path d7-c6-d5-c4-d3-c2.

Your ideas are very suggestive, Sam, Nick, Jeremy. I'm processing the information and will come here at this corner of the ciberspace later. Thanks!

José, Fergus: I don't think to delete broken logs is a good idea; it is something equivalent to destroy, to burn library's books. The good idea would be to know how is the cause for the logs become broken but overall to recover them.

Should the following logs be deleted?

    Thank you so much for your efforts. I'm already recovering the moves of my broken logs of Cetina Random Chess, Cetran Chess 2 and Universal Chess.

    José,
    
    How did you get the starting setups?
    I can access only to the list of moves, but not to the setups.

    Thank you very much, José. Unfortunately, some broken logs of mine are of games that were still in progress and not all the pieces had been moved, so I have not way to return them to theirs starting squares. Anyway some logs yes will be saved.
    
    I also love random positions, so I was the SECOND player punished the most...!!!

    We can update gradually the Piececlopedia devoting each day some minutes to add new piece descriptions by means of this subject of the Comments and Ratings section. The basic idea is to make little changes to the text show below, that it's a reproduction of the Piececlopedia index in which I have added a few new pieces to show how we can work on the matter.

    If anyone wants to contribute, copy the text written by me with HTML tags from the editing page and paste it into the box of the new comment where the additions will be done. Special, detailed descriptions of any particular piece can be made by creating one subject by piece with its respective link in the index. Subsequent contributors would do the same with the work of the last predecessor; thus, the last work would be always the updated Piececlopedia and periodically (every 6 months, say) Fergus could transfer the document to its original place.

    I propose to destinate a space at the end of the document for comments and a short explanation about what the contributor has done.

    Rich: 
    Could you indicate me in which chessvariant is used that Eurasian Pawn?
    Until now I'm considering only to add pieces that are used in
    chessvariants posted in this website in such a manner that I could utilize
    the corresponding icons.

    I think the pawn you mention is the Sergeant.

    Nick: Excellent if you add the WKC's pieces!
    
    John: Thanks for the clarification. I don't remember exactly where I read
    the expression 'dabbabah runner' for referring to the Adjutant. I will
    make the correction later. Then the Adjutant and the Emperor are two
    different pieces and this last also deserves its place in the
    Piececlopedia.

    I sign up for the tournament and pick Symmetric Chess whose setup is this:

    All the FIDE chess rules apply. When castling the king steps three squares. The Bishops Conversion Rule holds.

    I'll submit the corresponding items for rules and preset nextly.

    Fergus,

    OK, no problem; I change my choice for Euchess since it also can be useful as an introductory variant.

    Regarding the enforcement of the rules, I don't know how to do it. If you or any other could help me, receive thousand thanks beforhand.

    The preset is here.

    Fergus, 
    
    Thanks for your help. Already have copied the Victorian Chess preset code into the Euchess preset. Everything is working well except two points:
    
    1) Is not possible to make the pawn's sarting double move; it appears a message like this: 'You may not move a P from f3 to f5.'
    
    2) Is not possible to promote pawns on the 10th rank. When one enter 'manually' the move, for example P f9-f10; Q-f10, it appears this message: 'You may not promote your Pawn to a Q.'
    
    What can we do?

    💡📝Carlos Cetina wrote on Wed, Dec 9, 2009 09:50 PM UTC:
    Pawns double step and promotion have been fixed.
    The problem with the pawn checks is inherited from the Victorian Chess preset.

    Thank you very much. I'm ready for the tournament.

    The additional Commoner moves to rooks, knights and bishops increases the complexity of the game in a manner so exquisite that immediately induces me to transfer the concept to the symmetric setup on a 9x8 board.

    José: Would you like to try it? I bring forward a fantastic game! We could play it with or without dropping ministers, as you like.

    Following Fergus's suggestion for naming the symmetric setup, I would name this new variant: Ajax Bigamous Chess.
