A Castle in the Sky

5b1r/pp4pp/1n2k3/3pq3/3p4/3B4/PP1B2PP/3Q2KR b K - 0 1

The above diagram, showing a position with Black to move, was presented by Grandmaster Ruslan Olegovich Ponomariov as an instructive example of how counterintuitive the rules of castling in Fischerandom chess (a.k.a. chess960) at times appear to be. “At this position can Black prevent short castle by playing ... Qe5-f6?”, he asks. The answer is no — 1. ... Qf6 doesn’t prevent White’s h-side castling (2. 0-0), which, in the specific case, is performed by “Rook-move-only”, i.e. by the Rook jumping over the King. Not incidentally, the answer is also the solution of the puzzle/quiz, for after 1. ... Qf6 2. 0-0 Black might well resign.

40th International Dance Day

That’s what remains of the historical Oriuolo Theatre, which has been demolished to make way for a “cultural-technological” park. In its prime the Oriuolo Theatre, at just a stone’s throw from Piazza del Duomo, was one of the most lively civic theatres in Florence after the Second World War, only to be left adrift during the last thirty years.

Going Viral

I use this thinking in important life decisions, like whether to pursue a full-time chess career or continue my studies. Playing chess full time would give me energy for tournaments, but I wasn’t sure that energy alone would take me further — it’s a probability game. Then I thought about what I could gain from studies: They would show my brain a bigger world view. There was no right or wrong decision — I had to follow my heart. I went to the UK to study for a Master’s in Public Policy at University of Oxford.
I was thrilled when my actions paid off. In 2020, I became a full-time professor at 深圳大学 (University of Shēnzhèn), China. [Read more].

Chess is in my heart. I began playing at age five and, at 14, became the youngest woman to qualify for the Grandmaster title. By 16, I was the youngest woman to win the Women’s World Chess Championship. A significant achievement, but it felt like just a stop on my journey. [Read more].

A Day Like Today

Quod erat demonstrandum, any enmity and resistance to the will of the goddess can’t but prove vain and impious, and whoever dares to disobey her commands is doomed to eternal damnation.

17. Nc2! Black must have overlooked this move, when he played 14. ... Nxd3. 17. ... Nxh2. Alas for Nepomniachtchi, the “revenge of matter” ensuing from 17. ... Qxh2+? 18. Kxf1 Qh1+ 19.

19. Qg5! Nxf3+ 20. gxf3 Qh3 21. Bf4! Qxf3 22. Nd2 f6. Reluctantly, but the Queen had no good squares. 23. Qxg6+ hxg6 24. Nxf3 Bg4 25. Nd2. White dominates the board, and what follows is quite predictable, as well as 丁立人 (Dīng Lìrén)’s clockwork technique.


25. ... Be2. 25. ... Rad8 26. Ne3 makes little difference, since Black has hardly anything better than 26. ... Be2 whereupon would follow 27. Kf2 Bd3 28. Rg1 Kf7 29.

A Journey Back to Now

In the end, realpolitik triumphed. Anish Giri fell apart against Alexander Igorevich Grischuk, while Ian Alexandrovich Nepomniachtchi, by virtue of a draw with Maxime Vachier-Lagrave, entitled himself — with a round to spare — as Magnus Carlsen’s challenger for the World Championship match. And then all they have to do is to live happily ever after, especially because just today FIDE President Arkady Vladimirovich Dvorkovich announced that PJSC Gazprom will fund the most of the world’s mass events for the triennium 2021-2023. And so good luck to the newly challenger! Photo © Lennart Ootes.

As a consequence of COVID-19 pandemic, also this year most Liberation Day celebrations in Italy were moved online. Offline people, however, taking advantage of the quasi-yellow Sunday, did not forget to lay flowers at monuments and tombstones in memory of the women and men who fought to free the country from fascism.

Position after 35. ... Rc4-a4

Caruana, who today could neither afford to lose nor to draw, showed little or nothing against Giri’s Sicilian Defence, and, after 35 moves, he felt like it was time that he let the Champ know who is and who isn’t challenging the throne. 36. Qf2? Just one word, like “no”. Otherwise, White would have played, somehow for something, 36. Qc7! Rxa3 37. h4! (in which case 37. ... Ng6 38. hxg5 Ra4 is okay for Black). 36. ... Rxa3 37. h4 Qe5! Of course, with the White Queen on c7, this move would not be so strong because of Qc7-d8+ followed by Qd8xg5. 38. hxg5 Qxg5 39. Re1 Ra8 40. Be4


40. ... Ra2. 40. ... f5! transposes to the game. 41. Rb1 (41. Bb1 Qh5+ 42. Kg1 Ne2+−+) 41. ... Ra8 42. Re1 f5! 43. Bb1 Kf7 44. Re3 Rh8+ 45. Kg1 Nxg2! 0 : 1.

“Given that he was in a must-win situation, it was a big letdown for him. It’s hard when you play a position where you have to defend and you are in a must-win. You don’t have any enthusiasm whatsoever”, Giri eventually said. Photo © Lennart Ootes.

Qxb7± Vega Gutiérrez – Tjølsen, 39th Women’s Chess Olympiad, Khanty-Mansiysk 2010. Comparatively best may be, as suggested by Grandmaster Nick de Firmian (Mechanics Institute Chess Club Newsletter #964, April 17, 2021), 7 ... Bh5 8. 0-0 Bd6 9. Bg5 Nbd7 10. Nbd2⩲ “with a small edge to White”. 8. dxe5 Bxf3 9. Qxf3 Qxe5 10. Bf4± Qh5. The gain of the Pawn is not to be recommended, as after 10. ... Qxe4+? 11. Qxe4+ Nxe4 12. Nd2!

18. ... Nd7?! Black decides to sacrifice a Pawn in order to get rid of White’s Bishop pair. As such, it may have its points — the long-term consequences, however, shall not be encouraging to Black. 19. Bxf7+ Kxf7 20. Rxd7 Ke6 21. Rc7 Rhc8 22. Rxc8 Rxc8 23. Be3 a5 24. Kd2 a4 25. f4 Rd8+ 26.

30. ... Rd7? Allowing the exchange of Rooks is a huge mistake, since in the resulting same coloured Bishop endgame White’s extra Pawn will obviously tell. 31. Rd1 Rxd1. There is no reasonable way to avoid the exchange, since 31. ... Rb7 32. Rd5 leaves White dominating the board. 32. Kxd1. The transmission of the moves was temporarily interrupted due to a “blackout”, with any suspense, however, with regard to the result, as the winning technique is relatively simple. Reportedly, the game ended as follows: 32. ... Bf8 33. Kc2 Be7 34. b3 a3 35. Kd3 Bf8 36. Bf2 Be7 37. Ke3 Bd8 38. Kf3 Be7 39. Kg4 h5+ 40. Kf3 Bf8 41. Kh4 Bd6 42. e5 Bc7 43. Ke4 Ba5 44. Bg5 Bb6 45.

Position after 31. Rh1xh5

After surviving the vehement attack of Grischuk, who as usual handled his clock time very unprudently, Vachier-Lagrave must have felt, for the first time in the game, like nothing bad could happen anymore: 31. ... Rd4! 32. Rh1 (32. Bxd4 Qa3+ 33. Kb1 Rxd4=) 32. ... Rxa4+ 33. Kb1 Qd5. The mighty engines make it the same through a pyrotechnic variation: 33. ... Rh4! 34. Rxh4 Qd1+ 35. Qxd1 Rxd1+ 36. Ka2 Rd2 with a likely draw by repetition. 34. Qh5 Qxh1+ 35. Qxh1 Rg4 36. Bxe5


36. ... Rxg5? A grave oversight, probably due to nervous tension. Correct was 36. ... Re8! 37. Bc7 (or 37. Bc3 b6) 36. ... Bc5 with a perfectly playable game. 37. Qxb7! Rd2. Black suddenly realises that the Bishop is taboo, for if 37. ... Rxe5?? then 38. Qg2+ Kh7 39. Qh2+ winning the Rook. 38. Bc3 Re2 39. Qc8 Rg1+ 40. Kb2 Rgg2 41. Bxa5 Rxc2+ 42. Qxc2 Rxc2+. No better is 42. ... Ba3+ 43. Kb1 Rxc2 44. Kxc2 with a tablebase win, as Black’s King isn’t able to reach the b7-square; for instance: 44. ... Kf8 45. Kc3 Ke8 46. Bb4 Bc1 47. Kc4 Kd7 48. Kb5 Kc7 49.

Take to the Sky

Today, April 22 (Sol 18), NASA’s Ingenuity helicopter took to the Martian skies for the second time, just a few days after its first flight, which was made on April 19, and which was also the first ever powered, controlled flight on another world. Credit: NASA/JPL-Caltech/ASU/MSSS.

Earth Day

Today was Earth Day and everywhere there were solemn speeches about the urgency to protect the environment. Hence, the best thing is to hope that tomorrow will be another day. Photo: Matilde Guerri.

龙井茶 (Dragon Well tea)

Despite her early rising and long hours of streaming, in the morning of Wednesday, April 21, four-time Women’s World Chess Champion 侯逸凡 (Hóu Yìfán) appeared, fresh like a rose, to attend the inauguration of a new Training Base for Chinese Chess National Team in 杭州 (Hángzhōu), the capital of 浙江 (Zhèjiāng) that next year will host the 19th Asian Games. The inauguration, held at the 天元大厦 (Tiānyuán Building), was attended by a most influential circle of chess and non-chess personalities, including the incumbent Women’s World Champion 居文君 (Jū Wénjūn).
