Reply | 10 Jun 2008, 16:35:15 In reply to NimzoZugzwang Re: Draw glitch. The game was called a draw due to the Bare King rule which states a player cannot win by time forfeit if they have just a bare king left (just a king, no other pieces).

Reply | 23 Oct 2008, 22:45:50 In reply to AdminBrian Re: Draw glitch. So why isn't this glitch fixed yet? If the Bare King rule applies on this site, why doesn't the software reflect that in games? I'm sorry, but this is an issue of site integrity when a player cannot claim a draw that is rightfully their own. Admin, when will this be fixed? It's been going on since day 1. |

Reply | 27 Oct 2008, 00:47:04 In reply to chessplayer Re: Draw glitch. chessplayer, My response in the previous post reflected the fact that the bare king rule is implemented and working on Caissa. Is that not your experience? If the rule is (incorrectly) not automatically invoked in a game you play, make a note of the time and opponent and let us know and we will review it. |

Reply | 23 Nov 2008, 18:48:35 In reply to chessplayer Re: Draw glitch. Caissa didn't offer a draw to either player? A lone king is only a draw if the other person accepts the draw offer. The rule is there to protect the player that still has material on the board. If the player can mate the lone king before their time runs out then they can do so, if they don't think they can mate before their time runs out then they can accept the draw offer and avoid the loss should they be hind on time. In a timed game with two lone kings, it's still a win if the other player runs out of time instead of accepting the draw. pazuzu Edited on 23 Nov 2008 at 19:04:55 |

Reply | 24 Nov 2008, 06:02:48 In reply to pazuzu Re: Draw glitch. Hey Don, While I think your position explains the Caissa programming - I'm looking at it from the interpretation of what constitutes a draw. This is from FIDE: 5.2 The game is drawn when the player to move has no legal move and his king is not in check. The game is said to end in `stalemate`. This immediately ends the game, provided that the move producing the stalemate position was legal. The game is drawn when a position has arisen in which neither player can checkmate the opponent`s king with any series of legal moves. The game is said to end in a `dead position`. This immediately ends the game, provided that the move producing the position was legal. The game is drawn upon agreement between the two players during the game. This immediately ends the game. (See Article 9.1) The game may be drawn if any identical position is about to appear or has appeared on the chessboard at least three times. (See Article 9.2) The game may be drawn if each player has made at least the last 50 consecutive moves without the movement of any pawn and without any capture. (See Article 9.3) |

Reply | 24 Nov 2008, 07:53:12 In reply to chessplayer Re: Draw glitch. Hi John, I think Caissa's rule is based on the following, although I could be wrong. I'm sure AB will tell me if I am.  6.10 Except where Articles 5.1 or one of the Articles 5.2 (a), (b) and (c) apply, if a player does not complete the prescribed number of moves in the allotted time, the game is lost by the player. However, the game is drawn, if the position is such that the opponent cannot checkmate the player`s king by any possible series of legal moves, even with the most unskilled counterplay. |

In the case of this game - a draw is the only possible outcome. Time is no longer a factor, since the result has already been decided. Much like a stalemate is an instant declaration in the Caissa software (there isn't an accept draw option) - two bare kings shouldn't be any different. |

Reply | 25 Nov 2008, 02:56:54 In reply to chessplayer Re: Draw glitch. Well, Caissa does automatically offer a draw with a bare king but it can't make the player accept it. If a player wants to lose on time, that's up to them... pazuzu |

Reply | 27 Nov 2008, 06:05:56 In reply to pazuzu Re: Draw glitch. A little sarcasm detected, Don. Rules are around for a reason, and if Caissa doesn't follow accepted rules, then so be it. It seems the admin is content with your response on their behalf, so we'll leave it at that. |

Reply | 27 Nov 2008, 12:04:19 In reply to chessplayer Re: Draw glitch. Actually, I hope admin does respond. I've pretty much just been guessing what is going on. What would it take to get caissa to recognize every draw in every game and automatically score it as such? pazuzu |
