Game Reviews (and other rated comments on Game pages)

Ultima is very interesting, I play it with Zillions (not strong).
However,
I tried to find game annotations and I could not find any. It would be
nice
if you could give some games and some open sources. I wonder if there
exists opening and endgame theory.

Now that this comments page is up, I'd like to ask the regular 
readers of www.chessvariants.com to comment on Doublechess.
Doublechess is the first chess variant which I invented, and I
think it is my best one of all the ones I have created. It is my
pride and joy. At the time I submitted it to this site I had learned
that I was just a few months too late to enter it into the Large
Variants contest that was being held at the time. What a pity!
I feel that Doublechess would have been a very strong contender,
but by the time I first learned of this site's existence, the 
deadline for submissions for the contest had passed.

Doublechess' page on this site is unique in many ways. You
won't find too many other games on this site which have sample
games linked to it, and one of the games is annotated in detail.
(The link to my 'Doublechess web site' is no longer valid.)
Doublechess can be played by email on Richard's Play By Email
server, and I frequently conduct Doublechess tournaments on PBM.
The next one may be beginning in a few months and I will post
an announcement about it here (as I did recently for the forthcoming
Omegachess tournament which I will be running on PBM as well) when
I am ready to begin it.

Doublechess is a very simple variant. Simply lay two 8 by 8 chess
boards side by side. Use two chess sets, and replace the second
set of kings with a third set of queens. (if one does not have a
third set of chess queen pieces handy, substitutes can be used until
they are captured. Coins work well, for instance, a penny for a
white queen and a nickel for a black queen.) Set up the first army
of pieces in the traditional setup (RBNQKBRN) in files E to L
and the second army out in the wings (RBNQ, QBNR) in files A to D
and M to P. 

You will notice a few interesting strategic points about Doublechess.
Opposing bishops start along the same diagonals as each other,
often promting them to be quickly traded off if the opportunity
presents itself. If they avoid an early exchange, bishops of like
color can double themselves along the same diagonal to form a battery
in much the same way that one might double their rooks along the same
file in chess. Notice that whereas white begins with two dark squared
bishops on the left side of the board, or queenside (in Doublechess
terminology,
the 'queenside' refers to files A to H, and 'kingside' refers to
files I to P, mimicking the same sides of the boards which these
terms refer to in regular chess), and black has two light squared
bishops on the queenside. Likewise, white has two light squared
bishops to start the game on the kingside, and black has two dark
squared bishops on each side. Each side can try to exploit the other's
weaknesses on light or dark squares on each half of the board.

The way the board is set up, as players begin to develop their pieces
and pawns, the pieces tend to engage each other on each half of the
board in about the same amount of time as they do in regular chess.
In the middle game it is often the case where pieces will be interacting
with each other and threatening each other on each half of the board
completely independent from what is going on on the other side of the
board. In some ways then, Doublechess is like playing two games in one,
though one really needs to look at the board as a whole to truly
understand and appreciate the game.

There are other strategic differences between Doublechess and regular
chess which make my variant exciting and unique. It is more common
to sacrifice material for attack in Doublechess than it is in regular
chess, since one has so much material at one's disposal to attack with.
In Doublechess then, obviously king safety becomes extremely important.
Thus another axiom of dc is that it is quite possible to win despite
a material disadvantage, more often than one can overcome such a
deficit in regular chess. As long as one has enough pieces to launch
an attack, they can make things interesting.

I should also point out that the one rule that is unique and 
distinctive to Doublechess is the castling rule (see dc's page for
full explanation of the castling rule), and the pros and cons of
long castling vs. short castling can be long debated. It's another
twist to the game which makes it interesting. 

One advantage that my variant has over other CVs is that it only 
uses orthodox pieces, so it is very easy to learn how to play.
Perhaps more than any other CV, Doublechess has the 'feel' of regular
chess. There is a ZRF file available for download at the bottom of
Doublechess' page. I urge everyone who has not played it yet who owns
ZILLIONS OF GAMES to download Doublechess and try it out.
I welcome comments from everyone, pro or con, as to how they would
rate Doublechess as a chess variant. What are this variants'
strengths and weaknesses? Finally I would say that, although I 
realize I am very biased in the matter ;-)  I feel that Doublechess
is such an excellent variant that it deserves consideration as one
of this site's 'Recognized Chess Variants'  and as inventor of this
game I am necessarily disqualified from nominating it to that position.
Might someone else who has an equal appreciation for this game take
up the gauntlet and nominate it along with an eloquent essay on my
game's merits?

It would seem that I am not the first person to create a CV on an
11 by 11 board. (see my SPINAL TAP CHESS) It  would be interesting
to play a game of TERROR CHESS (for WHITE) vs. SPINAL TAP CHESS
(for BLACK) as a game of Chess Between Different Armies !!!

PETER ARONSON I challenge you to create a ZRF for such a game
IMMEDIATELY!! :-) I could then challenge Brian Wong to a game by
email! (if anyone has his address!) (mine is DavidNYJfan@hotmail.com)

though I suspect that TERROR CHESS has the more powerful army!
Then again who can say for sure?

Pawns move 1, 2, or 3 squares on their initial move and the en
passant rule is the same as it is in OMEGACHESS.
Each side may castle as its game's rules dictate.

How about the Tripunch Terrors, another army to compete against the
Fabulous FIDEs? :-) King and Pawns are standard. The rest of the pieces are
from Tripunch Chess, but they flip as pieces do in Weakest Chess- these
pieces have capturing and non-capturing modes, and can flip (as a move)
from one to the other. To keep the pawn line defended, the Reapers and
Combine start in capturing mode; the others start in non-capturing mode.

If flipping pieces are half as strong as regular pieces (and that seems to
be the estimate in the Weakest Chess article), then the Tripunch Terrors
are about 4 Pawns too strong as described. So we remove the ability to move
as a Bishop from the Harvesters and Combine... and then we should have a
game. So here's the official lineup: the Flipping Reaper, the Flipping
Nightrider, the Flipping Aanca, and the Flipping... the Flipping...

Give me some time. I'll come up with a name for that last one. :-D

It would seem that TERROR CHESS is identical to THE SULTAN'S GAME

http://www.chessvariants.com/large.dir/sultan.html

with the exception that the positions of the marshall and
cardinal are reversed. THE SULTAN'S GAME pre-dates TERROR CHESS
on this web site by three years. 

Nevertheless I still propose that my idea above for a variant
of chess between different armies would be intriguing. 

Oh and I would suggest variants with and alternately without
the 'Battle Move' when programming the ZRF for the above proposed
new variant. Players can decide for themselves which they prefer
to use.

Gee, now I wonder where he could have gotten the idea for this game,
huh? Well, you know what they say, 'immitation is the sincerest form
of flattery' so I guess I should be honored, eh? To anyone who is
not overly familiar with this web site I suggest you scroll down
on this comments page and click on the link for Double Chess below
or find it in the alphabetical index (the one with my name next to it).


Anyone can create a variant on a 16 by 8 board but it's not going to
have the same 'feel' of regular chess like my variant Doublechess does.
I have always felt that games with two kings are flawed. Chess should
be single-minded. Checkmate one king, period!

Tony, what you say about the added or diminished relative scopes of
the knights and bishops in double-board variants is true, just as
it is in larger variants to begin with (the knight is an extremely
weak piece in 10 by 10 variants) but the beauty of a game like my
Doublechess variant which I invented is that the knights still 
have their roles to play. Like I said before, pieces on each half
of the board tend to engage each other at the same rate they do in
regular chess. Pawns challenge each other, knights move up to the
third (or sixth rank, for black) rank to attack enemy pawns,
files open up for rooks and queens, diagonals open up for bishops
and queens. 

I think one point that needs to be made here is that in
Full Double Chess, stronger pieces are used, and that's fine,
if you are a player who likes new fangled pieces that can do neat
little tricks and jump through hoops. My Doublechess is more traditional,
uses only orthodox pieces and has the look and feel of traditional 
regular chess. So whether a game like my Doublechess or the new
Full Double Chess appeals to someone is going to be a matter of personal
taste, I guess. 

p.s. I would still like to encourage people to add comments below to
my Doublechess variant, for which I began a discussion.

I've played it and I agree with Ralph--the best way to introduce randomness
into Chess.

A checkmate rule I find satisfactory:
If a player is mated by a single move, the game is over.
If a player is mated by two consecutive moves, if taking two consecutive
moves would relieve the mate, the mated player wins the next toss
automatically and can play two moves.

For stalemate the rule is the same.

Perhaps Tutti Frutti Chess could be considered a Half Board version of
Double Chess, because it uses all possible combinations of the basic pieces
on an 8x8 board.

However, Double Chess has the interesting thought of having two Kings,
which seems to be an excellent inspiration for making sense of such a wide
board.

I do like this game, although the Cavalier is a very 'irregular piece'.
I propose to replace it's movement by the one of the Croocked Bishop!
This
would produce a very enjoyable game, don't you agree? :-))
The other pieces, I believe, are well balanced for 10x10 board, and the
fact that Knights depart from the 2nd row turns them more valuable in the
opening and during the rest of the game (a problem with other 10x10 board
variants that place them on the 1st row!).
