Is there a stalemate in Atomic Chess? I assume there isn't but just in case.

I have tried to play an Ambiguous Chess game and i can't say that i'm impressed with it. And that's because of the promotion rule. It really weakens the game the way promotions works.

Pawns are the soul of Chess and like that Pawns are the soul of Ambiguous Chess also. You can make nice sacrifices to just be able to promote. You can make spectacular moves to just give the chance to a poor Pawn to promote.
But this can't work in Ambiguous with the current promotion rules. The opponent will just choose the worst piece for you and the sacrifice would be pointless.

Countless endgames are meaningless with current promotion rules.

The rule from my perspective has to be changed such that the player and not the opponent to choose the piece in which the Pawn will be promoted.
That would create a much better game.

Just my 2c.

Perhaps i have this impression for Ambiguous Chess because of my first game. It has lasted 126 and still counting. :-) Perhaps this is a rare exception.

mangue: However, about repeating 3 times the same position or playing 50 moves without pawn moves, I am convinced no arbiter is allowed to interupt the game and therefore in case of a 3-times-repetition or a 50-moves-rules, there is no automatic draw...

Absolutely. I didn't speak about 3-fold or 50-move rule only about dead positions where it's an automatic draw.

KB versus KB is not a draw unless Bishops are of the same type(light squared or dark squared).
Moreover if bishops are of the same type and players want to continue they are not real Chess players!*** They can't force mate with any probable unskillful play and one can only lose on time or by resigning of the opponent, but even if someone does lose on time, arbiter will still declare the game as a draw as i've have repeatedly have said and do not repeat again.

If someone resigns the game he is in danger of being disqualified from the tournament or face any other penalties if he doesn't provide a sound reason for his resignation.

I'm not an arbiter and in all my career i have never seen anyone resign in a dead position but i believe his resignation will not be accepted and a dead position is an automatic draw even with resignation of one player.


***Chess is not who has the quickest hands. So to play a draw position that no one can win even with the most unskillful play and just try to out-time his opponent is ridiculous.

mangue:

Hi,

It's automatic. Most and in fact all arbiters would declare the draw, even if as i've said one player has lost on time.

What is the state space complexity and the game tree size for Cheversi? An approximation of course of the upper limit.

mangue: There is no automatic draw in chess, you have to claim a draw.

This is just wrong. If a position arose where no side can force a checkmate with any way, e.g because insufficient material occurred in the board, then it's an automatic draw no matter what. Even if one player loses on time it is still a draw. Such positions are called dead.

Imagine e.g a KNK position and the side with the single King to run out of time. Well it's still a draw.

there is almost no draw in dark chess, because you can never know if the 50 rules exist (how can you be sure your opponent did not move a pawn). So even after playing 500 moves, if your opponent still refuses to draw, you can do nothing.

But if you do not know if the opponent moved a pawn, you cannot claim a draw.

It is like the 3 times the same position. In dark chess, you often do not know what the opponent moved, so it is impossible to claim it.

Since in Dark Chess an arbiter is mandatory to exist to supervise the game and guarantee whether the rules are followed, it's easy to create a modification rule to the official Chess 50-move rule that could say, "If a position has arisen where no Pawn move and piece capture has taken place in the last 50 moves of both players, then game is a draw.".

No need for a player to ask about a draw.
