Does your website works with Firefox browser? I wanted to try out your game
(I was very interested because I am a Dark Chess fan), but was not able to
start a game.

I tried play with myself using Internet Explorer 6.0, but failed to start
the game. After I clicked on the oponnent I only saw 'Waiting
www.vervechess.com' in both browser windows, but the game didn't start.
How long is usually delay before the game starts?

Andreas Kaufmann wrote on Fri, Sep 23, 2005 09:24 PM UTC:
Ok, now I was able to start the game against myself (using Internet
Explorer). My mistake was that I didn't select an opponent in both
browser windows. Here is my first impression of this chess variant,
certainly this could be different if I played with a real opponent.

The attempt to create a real-time chess variant is very original, may be
Verve is a first such chess variant. I first thought that Verve is a
variation of Dark Chess (if not count real-time way of play), but then
noticed that it has complete different visiblity rules. It seems that in
difference to Dark Chess in Verve too much information is visible, why
didn't you want to use elegant and simple visibility rules of Dark
Chess?

Also not clear why you need to delay the game play when both players
selected thier moves. I would suggest the following move
synchronizations:

* game starts
* player A makes a move 
=> the move immediately made on the board, because player B is not moved
yet, player B doesn't know that A already moved
=> player A can't make a second move before player B moved or 10 (or
whatever) sec are passed.
* 10 sec are passed, but player B didn't make a move
=> player A can move now
* player A moves, 
=> move immediately performed
* player B moves, 
=> move immediately perfromed
etc.

By the way, does anybody tried to solve classical domination and
independence problems for chancellor (rook + knight compound) and
archbishop (bishop + knight). I.e.:

1) Is it possible to setup 8 archbishops on 8x8 board so, that they don't
attack each others?
2) How many archbishops are needed to attack each square on the board?
3) as 1) but for for chancellor (trivial)
4) as 2) but for chancellor (difficult).

I played on several similar servers: ItsYourTurn, SchemingMind, CowPlay as
well as here on Game Courier. Each server has something unique, but still
BrainKing.com is my favorite.

This is why I like BrainKing most:
* very nice and convinient user interface
* there are a lot of chess variants, including my favorite 'Loop chess'
(Crazyhouse clone) and 'Dark chess'
* ratings are calculated for each chess variants, so you can find opponent
of the equal strength (actually I prefer playing against stronger
opponents); this also adds more sporting interest in playing the games
* there are many tournaments being held (with many players participating)

Switching Chess. In addition to normal moves, switch with an adjacent friendly piece. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
Andreas Kaufmann wrote on Sat, Jan 7, 2006 05:57 PM UTC:
Well, and my play in this game with Gary was based on that such switching
is possible. Actually, before playing 22. Re1, I specially checked this
page to see if it is forbidden. The rule is important enough to be
explicitely mentioned. 

For example, let's consider position in chess: 
White: Ke1, Qe2, Black: Ke8, Qe7. 

If white now plays Qe2-e6, queen usually first taken off from e2 and white
king is temporarily in check. Still this move is legal in chess, because
this is the end of the move when the king shouldn't be in check. 

So, I suggest two resolutions:

1) I play another move instead of 22. Re1 and we start using a new rules
(pinned piece can't switch).
2) Gary takes a move back, which was based on assumptions that a pinned
piece can't switch and we continue without this rule.

Would it be difficult to implement ELO rating system here?

Ok, let's go with the option #1, please make your 21 move again and we continue with the new rule.

The following was posted to Wikipedia article 'Chess variants' by
anonymous editor:

'...Super Knight: Starting position for white is the same as in chess.
Black gets 8 pawns, his King, and a knight ...the SuperKnight. The
SuperKnight checks like a regular knight, but it can move to ANY
unoccupied square or capture any of the opponent's pieces. The game
should be won by white every time but only if he keeps his pieces well
defended. The white rooks are not defendable so blacks first two moves are
usually to capture white's rooks.'

Does anybody heard about this variant?

“Scandinavian” is probably Bughouse. This chess variant one of the most popular between chess players. In Russia Bughouse is called 'Swedish chess', may be in Bulgaria it is 'Scandinavian'. I also think that “Reverse chess” is losing chess, what can it be else?

Interesting attempt to create a synchronous version of chess, in which both players make the moves simultaneously: Xymyx chess. They created a very nice real-time server to play this game. I tried it out today - the game is a quite fun to play live!

How about contest to create a chess variant with incomplete information,
like 'Dark Chess' or 'Kriegspiel'?

Andreas Kaufmann wrote on Thu, Jan 26, 2006 07:51 AM UTC:
Another suggestion: contest to create a chess variant, which can be
conviniently played on usual chess board with usual chess pieces (may be
with more then one chess set, also it is allowed to use less pieces).
Piece moves should be also the same as in chess. 

Example of such variants:
* different capture rule (e.g. Crazyhouse)
* different goal (e.g. Extinction chess)
* incomplete information (e.g. Kriegspiel, can be played with 3 boards +
arbiter)
* different move order (e.g. Marsellias chess)
* different starting position (e.g. Fisher random chess or Una chess)
* random elements (e.g. Dice chess)
* multiplayer variants (e.g Bughouse)

I think this is broad enough to appeal to many people.

ZRF with a nice graphics can be downloaded from my homepage. ZRF is by J. Mark Thompson and Ivan A Derzhanski, graphics created by me.

Andreas Kaufmann wrote on Sat, Feb 4, 2006 11:14 AM UTC:
By the way, Alfred Pfeiffer found a nice way how to implement Glinski's standard notation in ZRF. One can simply use 'translate' command to give the cells desired coordinates: (translate ('g2' 'g1') ('g3' 'g2') ... ). I updated ZRF on my homepage (see my previous comment) with these changes.

Hi Mats! From large chess variants I prefer Capablanca chess variation with good initial setup. For example, Gothic chess or Embassy chess. The reason is that for ordinary chess player it is quite easy to remember moves of chancellor and archbishop and these new pieces add interesting tactical and strategic elements to the game.

Mastodon chess, white plays and checkmates in two moves.

An interesting chess variant suggested by an anonymous on Wikipedia chess article talk page:

...Nobody has ever cottoned on to my variant 'Schizo-Chess' where you play as normal until you capture- if you capture you switch to the opposing side and play a further move, if that is a capture you switch back, until there are no more captures. Aim is to win on your move, usually with a combination where you play the winning move as checkmate. 'Schizo' because each player has to play himself simultaneously, also- it does your head in..

HP-minichess. Small chess variant that could be played against a pocket calculator. (5x5, Cells: 25) [All Comments] [Add Comment or Rating]
Andreas Kaufmann wrote on Thu, Dec 21, 2006 10:43 PM UTC:
This chess variant is usually called 'Gardner minichess', since it was Martin Gardner, who first invented it in 1969.

Andreas Kaufmann wrote on Tue, Dec 26, 2006 07:55 PM UTC:
'Game History' menu item for Minichess in Zillions-of-Games says: 'The
recent play has suggested that the game is a draw with the best play.' 

Does anybody has more information on this? What is the best play in
Gardner minichess?

According to http://www.janko.at/Retros/Glossary/Andernach.htm the pawn
promotes first and then changes the color.
