| Aug-15-07 | | triangulation: mate can be forced in 33 moves from any position provided the king isn't winning a piece by forking the knight and bishop. |

 | | paulalbert: <Gilmoy> Just saw your comment from June. You are absolutely right. I was so focused on the mating pattern I use to force the B&N mate that I overlooked that it was immediate mate with a different pattern. Paul Albert |

 | | Jonathan Sarfati: <vonKrolock>Here is a video explaining the Deletang three triangle method. http://www.youtube.com/watch?v=PWZ7...
One chessplaying aquaintance said:
With the [standard] Philidor system I have around a 30% success rate. After viewing this twice, I'm mating fritz every time, its really simple and I could do it at 10 seconds a move with ease. |

| | paulalbert: I watched the video. Another interesting pattern to achieve this mate. I use the big W method taught in Tarrasch's Game of Chess. Really easy pattern because the K goes across the board always on 6th rank and N goes in big W,( in case of White B ) F7,E5,D7,C5,B7. B must go to appropriate squares to take squares away from K or tempo moves until K in appropriate colored corner.
This is so easy, even I can do this without sight of board. Once you learn an effective method, this mate is not really very hard. Paul Albert |

| Dec-20-08 | | WhiteRook48: Why not just play the mate in 1 or did White resign right after Kh1? |

| | Jonathan Sarfati: <paulalbert>, I didn't know it was in Tarrasch; has the book been published in English like 300 Chess Games? The method originally came from Philidor -- see a fascimile of his pioneering book "Analyse du jeu des échecs" http://books.google.fr/books?hl=fr&... |

| Jan-03-09 | | Kasputin: According to the chessbase site in the Amber Rapid tournament the players do actually see a board - it is a computer screen without pieces. But this article from the NY Times says that the players simply keep track in their heads: http://gambit.blogs.nytimes.com/200... I suspect that the chessbase description is the more accurate. Afterall, how do you settle any possible disputes? It would make sense if the moves are actually recorded on a computer - just not have the pieces visible to the players. But the NY Times article does mention the time control for the blindfold games in the event: 25 minutes per game with a 20 increment each move. Whether they see a blank chess set on a computer screen or not, this is impressive! |

| Jan-07-09 | | WhiteRook48: Why not just play 106...Bf3# right away? |

| | Jonathan Sarfati: I understand that it's a blank chessboard, and the computer plays only the opponent's last move with nothing else. Players enter move with a mouse. |

| | Jonathan Sarfati: In the all-GM game Robert Kempinski (2498) - Vladimir Epishin (2567) [E60] Bundesliga 0001 Germany (5.3), 07.01.2001, the winning side couldn't do it and stalemated after the 50-move rule had been exceeded http://en.wikipedia.org/wiki/Bishop... |

| Feb-01-10 | | Lucid Faia: Was this seriously played blindfolded? |
|
| Jul-26-10 | | I play the Fred: After playing over this game I went to practice the KBN ending again - I felt like such an idiot. Everything I'd read before about this ending stressed the need to force the enemy king into the same colored corner as your bishop - it never before occurred to me that the opposing king could walk into that mate on some other square:

| Aug-24-16 | | mulde: Is anything known about Mr. Deletang? His first name, his profession, where he came from, when he did live, ... Seemingly we only have his name. |
|
| Oct-07-16 | | nomaster: Monsieur Deletang was French, but lived many years in Argentina, in the first half of the twentieth century. He was an accomplished puzzle composer, but, funnily enough, not a strong player. He never surpassed second division in Argentina, which in fact is the third tier, since you have titled players, then first division for strong untitled players (there is no NM title in Argentina, but First Division would be the equivalent) and then the second, where Deletang played. There was no ELO back then but I understand it would have been a 2000-2100 level. But his creativity for endgames was unmatched. Not only did he created the famous NB mating method, he also claimed to have found the way to draw the QK vs RK endgame. Thanks to tablebases, we now know that the side with the Queen should win, so we can understand why Deletang never put this other method to paper like he did with the BN vs K. But still, his approach was almost unvincible in practical play OTB. During the Capablanca-Alekhine world title match in Buenos Aires, Deletang challenged several masters which were attending the event to play this ending against him and they couldn't beat him. |
