Atomic chess. Pieces explode when captured. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]

This is a test for how the Interactive Diagram can be used for variants with extensive side effects to their moves, by means of an (optionally) custom-supplied JavaScript function WeirdPromotion(fromX, fromY, toX, toY, promotionType) embedded in the HTML of the page that contains the diagram. This function originally was intended for specifying promotions not covered by the normal promotion rules (based on the specified promotion-zone size and the promoChoice or promoOffset parameters). E.g. for when a contageous piece is captured, for implementing non-rectangular promotion zones, or for vetoing certain choices dependent on the board rank where the promotion takes place.

promoChoice=QNBR graphicsDir=../membergraphics/MSelven-chess/ whitePrefix=w blackPrefix=b graphicsType=png symmetry=none pawn::::a2,b2,c2,d2,e2,f2,g2,h2,,a7,b7,c7,d7,e7,f7,g7,h7 knight:N:::b1,g1,,b8,g8 bishop::::c1,f1,,c8,f8 rook::::a1,h1,,a8,h8 queen::::d1,,d8 king::::e1,,e8

But the function can also be used to modify the board in squares not touched by the move ('side effects'). In Atomic Chess captures have a rather drastic side effect: the piece itself, and all surrounding non-Pawns of either color will disappear! The function WeirdPromotion supplied with this page takes care of clearing the board around the to-square in the required way. There is one snag: to cause disappearance of the capturer as well, it has to be erased on its from-square, as the routine is executed before the move is made. So clearing the to-square erases the capture victim, but the capturer will still be moved to it afterwards, and thus has to be erased pre-emptively.

Atomic chess can also be played live on although their version does not allow kings to be adjacent to each other. I think that FICS is better for live games (it has nicer graphics), although I have found that the wait time for an opponent tends to be longer for some reason.

I have read about a different variant of Atomic Chess in the book
'Alternatives Schach' by Lars Döring (german):

After a capture, the capturing piece and all pieces on the squares
orthogonally or diagonally adjacent to it are also removed, but with the
exception of the kings. A king may capture without being removed, and is
not removed when on a square adjacent to the capture.

A move may never put the King of the moving side into attack, neither
before nor after removing of pieces. So a king may never capture a
defended piece, even if the defending piece would also be removed.

In this variant, the initial advantage of white is much smaller.

the Atomic Chess you mentioned is different from this one .

According to this page, it was presented to GICS by connex. This page has
information about Vlasov's Atomic pgae and other links.

Atomic Chess was granted a French Patent in 1949. It was intended that it
would be played on a board of 12x12 and that the pawn would become an
Atomic bomb instead of promoting to queen upon reaching the eighth rank.
The king can be captured/destroyed in which case the next most valuable
piece becomes the 'king'. Two additional pieces were intended to be
- tanks and aircraft! The aim of the game was to eliminate all the
opponents pieces.

I created a preset and sent out an invitation to play atomic chess with an extra row of pawns over Game Courier.

I play atomic on Chess Live, formerly USCL. I can't stand ICC atomic because of the 'no-check' rule. FICS has much better players in atomic than Chess Live, but IMO the Chess Live interface is much better. And tom, in atomic white always has an advantage. Black just has to play to equalize, and then win. Having each side have two rows of pawns would compltely through off all the theory and study done by people like tipau and siggemannen. It would change the game completely. :)

Yes, Atomic is best played at ICC, And I have found a site that is really cool. Its great for Atomic chess. Its <b><u>without a doubt</b></u> the best Atomic Chess site online

Atomic chess is best played at FICS IMO, also ICC and the other chess
servers have atomic. Note that for example ICC has no check, and is thus
not really the same. Maybe you should add to the rules that: you may
explode your opponents king when in check/'checkmate'. For another
site on atomic: it has also links to
other sites...

Years before I heard of this Atomic Chess, I knew of another game by the same name: a 12x12 variant with Tanks and Aircraft, where Atomic Bombs only appeared as a result of Pawn promotion. It dated to the late 1940s (I think) and was patented in France. It doesn't seem that anyone here has heard of this variant.

i play a lot of atomic chess at and have decided that white knights are too powerful. how about giving each player 2 rows of pawns? this will make it harder for knights to start, and also harder to break through the opponents defences.

This is another chess variant which can be played online on <a href=></a>. It belongs to the most popular chess games on that site.
