joshi tm: Since the player in disadvantage has the swap option, the player in advantage should try to play those first two moves in balance, otherwise White will swap and probably win.


I'm not convinced by this argument. The advantage of black isn't in the first move, it's the fact that he has the last move. Swap rules work (although I won't say 'fine') for games where there's an advantage of having the first move. But in Cheversi, it's the advantage comes at the end.

there is some problem with this site right now. But it will be ok, this is a serious site. Yes, the last move may be very interesting and the second from the last also and so up the staires to the first move.
How about adding another interesting feature to the above, original rules: move has to be with like figures. When started with a King, a King has to follow, after a Bishop, another Bishop has to follow ...

Subject: Re:
dicepro: I'm unable to get onto the chessvariants link you gave right now - but limiting the move to a privious played attacked space might be good - since which can just plan to put the king next to last to make sure the queen is put in a limited area.

As for MadMonkey's Dark Cheversi - the problem would still be black last move would be an advantage. But an idea that just came from that - make it so both players move at the same time.

That is both players pick a spot on the board to place a piece at the same time. Then after both players choose, as long as they do not pick the same spot - then play the piece. If by chance the 2 players pick the same spot, have them replay that move - but don't allow anyone to play that spot for the next move.

In this way - there would not be a first & second player.

yes, it looks there is infinite number of different path to improve Cheversi ... but I am coming to a conclusion, that the original (published at chessvariants) version would work fine. White in the last move can force very limited numbers of ways for Black to respond ... this way the last black's move wouldn't have to be a killer one.
What do you think about this.

Subject: Re: Nice idea
dicepro: Remember when we had this conversation last year (i think lol)

I think Dice is the obvious change, but having another quick think (as i have to rush to a dart match lol), maybe some kind of Dark Cheversi, where neither player knows what opponents pieces have been placed until the game end. Once a piece is placed, that square becomes unavailable and only the player would know what piece is there.
Once all pieces are placed. th final board and scores are revealed

Well something like that back soon

Subject: Nice idea
it's interesting and kind of satisfying that the game of cheversi stirs so much brain power of our friends. My original idea was to play this game with all the pieces (including pawns) ... it could be really crowded and situation can change very rapidly.
Now, look please at the original rules I posted to chessvariants page. The rules say that a piece can be put ONLY on a square attacked by the opponent in the last move. I suggested to Fencer to play variant no.3 where tyhe player is free to chose any square. Maybe the original version was the best idea I had ... in this way I can influence greatly the moves of my opponent, forcing him/her to some unwanted positions ... Now I can see that too much freedom is not freedom at all. Please read the original rule.

There is something that I've been thinking about - but I would have to sit down and play around on the exact setup and such - but lets called it:

Choice Cheversi

The choice is that before the game starts, you decide which set of pieces you want to play with. (and you will not know your opponents set until after you start - or possible keep it hidden and learn 1 piece at a time as they play)

For example, let say there are 4 sets to choose from.

1. (power) - 1 Queen, 2 Rooks, 1 bishop, 1 knight
2. (mid-power) - 1 queen, 2 bishop, 2 knight, 1 king
3. (mid-bulk) - 2 rook, 2 bishop, 1 knight, 1 king, 1 pawn
4. (bulk) - 1 rook, 2 bishop, 2 knight, 1 king, 2 pawn

So it would be a game of power vs. quantity - you can choose a few powerful pieces - or a more less powerful pieces to help block the power play.

AGAIN - the above is just off the top of my head - I would have to sit down, try to figure out the "strength" of each piece in the game to come up with a good set of pieces. But as you can tell - if you have "power" pieces, you have less moves - and if you choose more bulk, you will have more moves - in which you can block the power pieces

how about using a dice ? this what, as I remember, Big Bad Wolf was suggesting long time ago ... 2-knight, 3-bishop, 4-rook, 5-queen, 6-king and 1-joker (any piece chosen) ... and like in Dice Chess, program would detect which piece is still available to play ...
Or, this is something I was suggesting ... that maybe this game should be played on a 6x6 board ... making it more crowded and difficult to get the long shot in the last move ...
What do you think ?

Extra pawn is also a good idea to make another game variant.

Those two new extra games could be submitted to Fencer. But the original version is still imbalanced, and these suggestions' rules are so different in comparison to the original, those are total different games.

dicepro: Well now would be a good time for any type of rule change.... since there are under 50 current games going on.

I don't know if Swap is good - seems like everyone would still try to be black. Maybe give white an extra piece, a "pawn" for their last move.

Anyway, if anyone can come up with a good rule to make the game more equal - this is the perfect time to get Fencer to change it since very few games are going on right now.

Cheversi is a quick, nice game, but there is a problem - even with the rules change in January, Black's odds are still too high to win. Any ideas to solve the problem?

Edit: I know something;
Swap Cheversi: White plays his king in the extended center, then black places his queen anywhere, places another White and black piece on the board and White get the Swap option.

nodnarbo: well, maybe 2 or 3 bombs could be a better strategy game, and if they all get captured then 'best of luck' on trying to check mate the king. I think captured the king is also another win, but I'm not sure, since I haven't played it in over a year.

no your opponent doesn't know which piece has been chosen. that's a lot of the strategy of the game. picking the piece to be atomic and making sure it doesn't get captured, because if it's captured it's the same as any other piece, it doesn't explode

SKA: There's certainly room for both versions here. Just have to name one of them differently or call it version 2 or something. IYT's version could be called Atomic Bomb Chess, while leaving the BrainKing version as Atomic Chess.

Does the bomb in the IYT version blow up nearby Pawns too? It certainly is different having it possible to blow up both Kings for a draw too. Do the players know which piece their opponent has chosen to be the bomb?

Subject: (IYT) It's Your Turn's=> Atomic Chess version
Atomic Chess (CT)
Atomic Chess has similar rules to regular chess, except that at the beginning of the game you designate a piece to double as the 'atomic bomb'. You can detonate this piece/bomb at any time during the game, which will destroy that piece and all pieces in squares immediately adjacent to that square (both straight and diagonal squares). You can detonate a piece to get out of check. Detonating a piece counts as your entire move, so you cannot make any other moves on the turn that you detonate your piece.

If your opponent's king is in one of the detonated squares, then you win the game, otherwise you'll need to checkmate the king. The exception to this is if both kings are blown up at the same time, in which case the game is a draw. If you blow up your own king during a move, you lose the game. All other rules are the same-- castling and en passant are enabled in this game.

At the beginning of the game, you will be asked to 'place' the atomic bomb on a piece. Then your opponent will be asked to do the same, and the game will begin. The atomic piece stays on the same piece throughout the game, and if that piece is captured or destroyed, then you will not be able to detonate an atomic piece for the rest of the game, because your bomb is gone.

To detonate your atomic piece, click on the DETONATE ATOMIC PIECE link under the game board. Remember, this counts as your entire move, so you have to click this before clicking on anything else.
======== ========== ======== ========== ========

Has anyone here played this version? I thought the version on BrainKing was the standard way to play it. IS this way of playing as good of a game? I imagine the play is a lot more like regular Chess than BrainKing's Atomic Chess is. :)

Subject: Re: short games of Dice Chess

mangue: I admit to having a particular fondness for defensive play and for endgames in nearly all variants.  Variants in which those are less frequently seen, or which call for no skill in those areas are less appealing to me.  I consider the thematic Dice Chess Nc3-Nb5-Nxc7-Nxe8 (and mirror image for Black) maneuver to be a blemish in the game itself.  In my experience, it's only executed in about 5% of games, but is threatened in perhaps 25%.  It reminds me of the scholar's mate in chess: fascinating to beginners, but a horrifying thing for a knowledgeable kibitzer to behold.


I'm also not thrilled by compulsory king moves in the single-die version, although one can adjust one's play to account for it, both offensively and defensively.  Two-dice versions typically don't suffer from this defect; dice rolls alone cannot compel a king move, in versions I know of.

To make the game more interesting and to avoid fast losses in style Nc3-Nb5-Nc7-Nxe8, immortality for the king for let's say first 10 moves would be perhaps helpful.

Also a variant where pieces are more likely to be rolled if there are more possible moves with those pieces would be interesting, this was mentioned earlier, but it can be different named game, for example advanced dice chess .

May be some immortality in behemoth chess as well, but I didn't try this game.

I hope you understand my concept about "playing one move implies declining draw offer"

Well, this is a luck game, so a K against K endgame is not draw

A simple solution is to play your move, and, after your move have been completed, if the behemoth position is not to favorable for you, offer draw at that time, which seems fair, am I wrong?

Modified by dresali (30. July 2007, 21:03:04)
I'd say there's a minor fluke in the way offering a draw works in Behemoth chess, cause when you offer a draw, your opponent gets to accept it in a different situation (with more information) which kinda makes offering a draw quite a bad idea, even in equal positions. (I'd say in about every other game, your opponent has to accept or decline the offer in the same situation as it has been issued.)

Say there are only the kings left, and the Behemoth is not attacking any king, its quite an even position, but offering a draw gives a lot of advantage to your opponent, since he gets to see where the B. goes before deciding, and will decline if the B. attacks only your king and accept if it attacks only his king.
So with reasonable players, the draw feature is quite meaningless in such situations, even if both would prefer a draw.
Maybe it would be a consideration to relay draw offers in Behemoth chess before the Behemoth move is executed,
on the other hand this is probably just a minor incoherence not worth the bother, but it was annoying me once or twice when i would have liked to have a draw, but offering one would have been unwise.
