English grandmaster John Nunn was the top seed in the over-65 section at the World Senior Championship, held in Italy last month. A series of crisp attacking games put him in the lead with 6.5/7. But an uncharacteristic miscalculation in round eight saw him lose a miniature against Danish grandmaster Jens Kristiansen. Going into the 11th and final round, Nunn still trailed by half a point, so his fate was no longer in his hands. As the games unfolded, Kristiansen had the draw well within reach, but succumbed to a neat endgame zugzwang against Jose Luis Fernandez Garcia. Meanwhile, against Valentin Bogdanov, Nunn spun a slim advantage into gold with a leisurely king manoeuvre from the h-file to the b-file. Nunn took the title with 9/11, ahead of a quartet on 8.5/11.

The young team from Uzbekistan, who took gold medals at the Olympiad in Chennai, came close to repeating that achievement at the World Team Championship in Jerusalem last month. They cruised through the group stage, quarters and semis, and met China in the final, who got there despite fielding none of their elite players, such as world No. 2 Ding Liren. The match promised to be close, and it was China who triumphed. Their star player was Jinshi Bai, who scored 8.5/11, including this crucial win from the final. Bai Jinshi-Shamsiddin Vokhidov World Team Championship, Jerusalem, Nov 22 In the diagram position, 34 Qa7 Rc8 is balanced, but Bai found a clever counterblow. 34 f4! The point is that 34…Rxb6 35 fxe5 Rxc6 36 exf6+ Kh6 37 Rd7 wins. But 35…Ng4!

When Magnus Carlsen renounced his world championship title earlier this year, one of his stated goals was to focus on other events, without bearing the burden of preparation for a regular title match. The Meltwater Champions Tour is an important battleground for the Norwegian, and he showed devastating form at the Tour Finals in San Francisco earlier this month. Initiated by Carlsen during the pandemic, the elite series of rapid tournaments is mostly played online, although four out of eight players travelled to San Francisco for the finals. This was the only decisive game from Carlsen’s first-round mini-match against the runner-up.

‘In fact it is now conceded by all experts that by proper play on both sides the legitimate issue of a game ought to be a draw…’ Those words were written by Wilhelm Steinitz, who became the first world champion after beating Johannes Zukertort in 1886. But their 20-game match saw 75 per cent decisive games, a quantity of bloodshed that would be unimaginable in the 21st century. By comparison, Magnus Carlsen has played five world championship matches, in which less than 25 per cent of the classical (slow) games were decisive. It is not a matter of style, but rather of skill – the fact is that modern players make far fewer mistakes.

The chess lexicon has adopted a useful word from German, fingerfehler, fehler meaning mistake or error. Sometimes, the hand does not obey the brain. Imagine that you are busy contemplating A, followed by B and then C, and engrossed by the consequences of C. Meanwhile, the hand is eager to get involved, and picks up the piece to make move C. Standard competition rules are that once you’ve touched a piece, you must move it, so even if you catch yourself before executing the move, the damage from picking up a different piece may be terminal. Mercifully, I don’t recall ever doing this, but I’ve come close enough to know that the phenomenon is real.

‘I can comprehend Alekhine’s combinations well enough; but where he gets his attacking chances from and how he infuses such life into the very opening – that is beyond me. Give me the positions he obtains, and I should seldom falter. Yet I continually get drawn games, even out of the King’s Gambit!’ Those words of admiration for the fourth world champion are usually attributed to Rudolf Spielmann, a strong contemporary of his in the interwar period. I am struck by the same sense of awe when I watch Shakhriyar Mamedyarov play. The grandmaster from Azerbaijan was at his sparkling best in the early rounds of the Aimchess Rapid, the latest online event in the Meltwater Champions Chess Tour.

Vishy Anand’s eyes lit up as he described a beautiful variation from his game with Shakriyar Mamedyarov, played at the European Club Cup in Mayrhofen, Austria this month. The first diagram shows a variation which could arise if Mamedyarov had tried 33…Bg5!? 34 Rxc4 Bxe3+. (See left game) 35 Kf1 is tempting, since 35…Bxc4 36 Qa4!, threatens to capture the Bc4 and put Black in check at the same time. But 35 Kf1 d2! is a powerful spoiler, since after 36 Ra1 Bxc4+ the mighty pawn and bishop pair are a match for the queen. Placing the king on g2 or h1 leaves it vulnerable to a check from d5. Anand had planned to play 35 Kh2! Then, after 35…Bxc4 36 Qa4! disrupts Black’s coordination. He saw that Black might try 36…Bf4+ 37 Kg1 Be3+. But then 38 Kf1!

Judit Polgar, the strongest female player of all time, conducted an enchanting interview in the commentary room during the Chennai Olympiad. Her interviewee was Charvi Anilkumar, an eight-year-old girl from Bangalore. Asked about her dreams and ambitions, she announced confidently, ‘I need to play in men’s section and I need to be a grandmaster, and world champion!’ Polgar was evidently delighted and expressed her hope to one day see Charvi playing alongside men in the Open section of a future Olympiad. When she was an active player, Polgar was the top-ranked woman in the world from the age of 12, but she avoided women’s tournaments. Her pursuit of stronger opposition saw her peak at no. 8 on the international rating list.
