I posted nine of them with a two day time limit. Play one game color your choice, or two games of each color. Good luck.

promoting your last pawn would be a suicide move. In Atomic, you cannot explode your own king, so I wonder if you can extinguish yourself in extinction.

Anyway, it is very improbable to happen!

RamblinMan:
Yes, the loss of the Queen does end the game. She is the only one of her kind. I won a game this afternoon by capturing my opponents Queen. The rules should say King, Queen, Two knights, etc., etc. I hope this helps.

you got it, Ramblin. The only possible downside to promotion is by promoting your last pawn, you'd lose the game. I've seen a few cases where selective promotion has won games for people, some to Qs, some to other pieces that were "endangered." Honestly, though, promotion doesn't happen nearly as often as regular chess.

But both of your questions are spot on. 2 kings is no different than 2 queens.

In the rules of this game it clearly says The player who captures all opponent's pieces of one kind, i.e. all eight pawns, both knights etc., wins the game. and it also says It is also possible to capture the opponent's king (and that finishes the game immediately since the king is the only piece of its kind). but I am guessing that the loss of a Queen would end the game as well, it being the only one of it's kind. so I would think it should be protected as much as the King. and I wonder as well if I promoted a pawn to Queen would give me two and loosing one would not end the Game If the same would be true of a King. promoting a pawn to a King would Give me two and I could then still loose one and not loose the Game?

Extinction Chess
This game (by the way, great invention of Mr. R. Wayne Schmittberger) follows the same rules as the standard Chess (starting position and piece movement) with these differences:

There is no check or checkmate.
The player who captures all opponent's pieces of one kind, i.e. all eight pawns, both knights etc., wins the game.
It is also possible to capture the opponent's king (and that finishes the game immediately since the king is the only piece of its kind). Because there is no check, a king can move to a square which is attacked by an opponent's piece or make a castling through such square.
Pawns can be promoted to any piece including a king. However, if the player promotes his/her last pawn, loses the game because he/she loses all pieces of one kind - pawns.

This is a valid point. I have never come across. and doubt I shall. But I don't see why this is not acceptable as with any other promotion.

Fencer, could you explain why this is not acceptable?

as i noticed in my games it seems clear to me that you should take care of following in amazon chess:

1) weak points h3/h6 in flank openings
In flank openings (kings fianchetto; kings indian and so on) it is obviously that the classical battery of Bishop e3+Amazon d2 deadly points to point h6 (and black vice versa). i won some games with this strategy.

2) weak pawns h3/h6
i think you must take care with moves as h2-h3 or h7-h6. in classical castling positon a sacrifice of a bishop/knight and then the upcoming amazon often leads to the single mate by the amazon (as we discussed)

3) exchanging the amazons
exchanging the amazons leads to a "normal" chess, and then the stronger chess player is in advantage. in my opinion weaker chess players should not exchange the amazons in general. one example is one game form me against chessik - i think my opponent made a mistake to exchange the amazons.

4) get out the amazons in the opening
in chess there is a rule in opening - do not let out your queen fast! i think in amazon you cannot say that belonging to the amazon, because the amazon can threat much more than a normal queen.

ahhhhh, the chestnut surfaces again ... Fencer has already spoken on this elsewhere and is strongly against automoves ... so unless he has a significant change of heart it will not be happening.

i think it would be very usefull for antichess to implant conditional moves;because there are often compulsory series of moves,so games could be played quicker

Fortunately two bishops can mate.
Sadly bishop+knight can't.

Also there is no bad corner color bishop, in k+p/k endgames no difference between a/h and other pawns, no chance to draw in kq/kp :-)

All normal chess rules apply.

Ugh, learn something new about the rules everyday.

In a game, I already have my opponenet checked 2 times, with just 1 more check needed to win the game.

My opponenet just put me in check for the first time, and even though I can move my bishop and put my opponent in check for the 3rd time and win the game (like the rules say), I have to instead get my king out of check. (Which will allow my opponenet to probable now get 3 checks on me)

Are these rules correct?

I have won the tournament. The last game ended with the King getting draped and had lots of trouble going on during it.

Thank you to all the entered and played. Thanks for a good match Mely.

As I was knocked out of it a few weeks back, I sent Fencer the money for the winning prize of a year's Rook membership. Today Fencer sent me a message that he'd received the money and took it to the bank. The first round is just about over and the section winners will be playing it off shortly. I'll post their names when it's happening. Good luck to all that are still in.

Congratulations to Matarilevich, he swept our section and will be playing for the championship. He is also the first person to knock me out of a tournament as I've won every other Dark Chess tournament that I've entered here or on It's Your Turn. You guys in the other section will have your hands full playing him for the prize and championship. I look forward to checking out the games.
Current standings are here:

Since I'm eliminated, the prize is a full year Rook membership. Good luck to all that are left.

It should be fixed now.

Then I recommend to play it unfixed. I still have no time for it.

the fellowship fomento-beraun club needs to players for its anti chess team! newcomers are welcome! tycho and i started to play this game now! :-)

Just a reminder that you need to fix my game. It times out tomorrow.

I would like to play in the upcoming anti-chess tournament. Anyone looking for a (rusty, but at one time decent) player for their team?

yah... i cant believe that i got into that position twice :-)

LOL!

The k/r vs. k ending seems to be a speciality of chessFriendJosh : http://brainking.com/game/ArchivedGame?g=490665

In my game against FriendJosh an endgame king+Rook-King occured. My opponent in my opinion defended correctly, staying with his king in the "centre" of "lefr/right" side of the board.

i think mate is possible with correct zugzwang..but not sure..

I'll fix it soon.

I did. Number 186. Can you also fix the game, or do I need to play on down a pawn?

mating with queen is possible. you have to prevent the king going out over the edge. but i think, it makes the time to mate only longer. until the opponent's king is not at the last or first horizontal line he can escape one line back at the other side, ok.

I take that back. You can edge the king over on the back rank with the queen until he's close enough to the king to force mate. I think.

LOL. because no force to the edge. I'm not convinced a king queen vs king is a forced win either for that matter.

and three ..:-)?

but 2 rooks shoud win ;-)

I have had an ending with king/rook (me) vs king and it was only draw :-(

slowly i am getting the feeling of the threatments of bishops over the edge, but not the pawns, yes, i often forget it! by the way: what about endgames in cylinder chess? can a queen only mate (suppose yes), rook (suppose no).

i miss that more than anything, the old pawn protection from edge to edge. :)

oh, of course, you are right!

since you moved already I think 18...Ba6 was best.

in one of my game against caissus (after 18. move of my opponent) i fall in a nice trap of douple piece attack (attacking my bishop b7 by the opponent's rook at h7 and threating mate at h7) - nice!

Also interesting is the image of eternal rotating rook between a1 and h1 if there are no other pieces. Rotating without limitation! Nice :-)

Indeed, since there are no edges, castling is not the same advantage. In fact the rooks start connected, so castling doesn't even achieve that.

There are really no center squares either so tactics are much different than regular chess.

yes caissus. it seems that castling is not necessary in cylinder.
i saw some opponents opening with Na6/Nh6 - blocking bishop's lines a1-h6 and f1-a6.

In Cylinderchess many games start with b3 or/and g3,with the developing of the bishops and it seems that the best place for the king is in the middle,without castling. Comments?

please! with one more player in the fomento-beraun club team the cylinder chess team tournament can start! so please join our fellowship and our team!

the single mate is a dangerous feature.
look here

Sorry for the late reply, but I just noticed that post :-)

The immediate problem with that game is this: The only reason the maharajah can mate itself is because of the presence of corners. Without corners, that possibility disappears (in other words, the maharajah cannot checkmate on a cylinder) :-)

Please post it to the Bug Tracker if it's not already there.

If this is an ancient variant then its rules should be different. I don't know how was ancient indian chess but with old western chess rules I think this variant is more balanced.
The problem is black can proceed without giving any hole in its position. With old rules black has two holes (b7 and g7) at first and moving ahead without giving a hole to white needs ultimate cooperation of pieces.
I think the crowned chicken has real chances of survival , give it the power of modern Bishop also, then it will be a dragon :)

Yup, looks like a bug to me (opponents pawn should have been removed).

Fencer should be able to fix it. You may want to send Fencer a message, or post about it in the Bug Tracker since I don't think Fencer reads all the boards every day.

I tried to make an en passant capture in http://brainking.com/game/ShowGame?g=502536&i=22. It sort of worked. My pawn went forward instead of diagonally, but my opponent still has his pawn.

personally i think that black shoudl get to start 2 more files of pawn up farther. evening things out. blacks pawns are jsut to slow in this game. there always 1-2 tempos behind. i think that the added 2 advanced files will even out things.
