The diagrammed position — a basically theoretical one — was reached in the crucial fourth tie-breaker game between Koneru and Muzychuk. After three tense draws, Indian Grandmaster was the first to succumb to a nervous breakdown, tragically blundering a piece:

Time to Think
Speaking to NRK right after his defeat in the semifinal of the 2nd World Fischerandom Chess Championship Knockout Tournament, Magnus Carlsen, without periphrases, called his own play “pathetically bad”. Indeed, he committed an unusual number of mistakes, while instead his opponent, Ian Alexandrovich Nepomniachtchi, “played fast and tactically. It was very frustrating. I stood clearly better in all four games, but I was unable to get more out of it”, Carlsen said. “I had neither the time nor the disposition to play my chess. It is also one of the reasons why I advocate to play Fischer’s chess with longer time controls and classical chess at a little faster cadence”. Photo © David Llada/FIDE. |

Position after 40. Kh2-h3
In a must-win situtation, and in the middle of a mutual time-scramble, Muzychuk was lucky enough to be the one who made the next-to-last mistake! White’s 40th move, in fact, was a mistake, but Black’s reply is, alas for Koneru, a much more grave error:
40. ... Qf6? 40. ... Rxf2! would have probably saved a draw (41. Qg3 Qh5+ 42. Qh4 Rxf6=) and given the match victory to Koneru. Now White, thanks to back rank mate threats, wins the a-Pawn and the game, thus taking the match to a tie-breaker tomorrow.

One Flew Over the Cuckoo’s Nest
On Tuesday afternoon, September 27, 2022, the awarding ceremony of the inaugural “深大青年先锋奖章” (“Shēnzhèn University Young Pioneer Award”) was solemnly held in the Alumni Plaza of 深圳大学 (Shēnzhèn University), coinciding with the 39th anniversary of the founding of the insitute. Four-time Women’s World Chess Champion 侯逸凡 (Hóu Yìfán) (pictured above third from left), a full Professor at the School of Physical Education, Normal College (Faculty of Education), by virtue of her serving as a role model for young generations, won the nomination award out of 20 nominees. “The chessboard has boundaries, but education, knowledge, imagination and creativity can be infinite”, 侯逸凡 (Hóu Yìfán) said. “As with so many things in life, even in chess there is no simple one-size-fits-all answer”. She hopes to be able to unveil her true self with the same courage and daring as Bobby Fischer, her imperishable chess idol. “As a teacher I am still a newcomer and need to continue to learn and grow”.

A Voice from the Wilderness
Hosted, edited and produced by Dr. Tricia Jenkins for Worldwide: The Unchosen Church, this 30+ minute episode premieres newly discovered tapes of 11th World Chess Champion Bobby Fischer, recorded between December 1976 and January 1977, discussing his experience with the Worldwide Church of God (WCG), a doomsday cult to which he donated large sums. The original tapes, whose best highlights are featured in this episode, were about 5 hours long, and most of the content was transcribed in full on the pages of Ambassador Report, 1977 (AR2) under the title “Bobby Fischer Speaks Out!”. |
