Chess

Detecting vulnerabilities

I suspect many players perceive the chess board in rich contrast, like a heat map. Glowing bright red are those pieces which are attacked but not defended. A gentler shade applies to pieces which are vulnerable to attack in future, or squares that are ripe for occupation. In the diagram below, the intrusion 10 Nd5-e7+

Titles bonanza

At the beginning of August, seeing his outstanding performance at the Fide World Cup in Sochi, I wrote that Ravi Haria ‘must now sense that the grandmaster title is well within reach’. But who could expect that he would achieve two more grandmaster ‘norms’ before the month was out? Haria, 22, now has all three

Best-laid plans

A popular conceit among chess authors, particularly dead ones, is to describe a fine game as the execution of a multi-stage plan. In fact, a close inspection often reveals that the plan could only have been mapped out in hindsight, and the loser’s fate was entirely avoidable. Grand plans are overrated, but modest plans are

Remembering Evgeny Sveshnikov

There be dragons! What we now call the Sveshnikov variation of the Sicilian defence was, in the 1970s, largely uncharted territory, and viewed with deep suspicion. Its modern name immortalises the Russian grandmaster whose pioneering analytical efforts, and practical success, put the variation on the map. Evgeny Ellinovich Sveshnikov died on 18 August at the

Containment

‘Exchange chess’ (also known as bughouse) is the chess equivalent of a three-legged race. It is played in teams of two, on adjacent boards with opposite colours, and it works best when nobody takes it seriously. The only essential rule is that when you capture an opponent’s piece, you hand it to your partner, who

Calculated risks

Two years ago, the brilliant young Polish player Jan-Krzysztof Duda made a baffling decision. In the second game of his knockout match with Wesley So at the Moscow Grand Prix, Duda needed just a draw to advance to the next round, having won the first game with remarkable ease. Perhaps he was mindful that when

The Fide World Cup

As I write this, the Fide World Cup is underway in Sochi, the Black Sea resort in Russia which hosted the 2014 Winter Olympics. It’s a thrilling event for spectators, who get to watch high-stakes chess in all its forms — fast, slow, wonderful and blunderful. The main knockout event began with a field of

The king of no castling

In the body of chess rules, castling is a clumsy protuberance. Once per game, you get to move king and rook at the same time, with a bewildering list of exceptions. (One dreads having to broach these gotchas with a novice opponent who has castled improperly.) Despite its convoluted logic, castling is nothing more than

Kasparov’s tailspin

In a game between top players, the opening moves signify not only the battleground they have embraced, but also the terrain they have avoided. In his prime, Garry Kasparov’s opponents would often duck the most critical choices, fearing the champion’s formidable advantage in home analysis of complex positions. But those who yielded an inch at

Lock-picking

In his autobiographical book Surely You’re Joking, Mr Feynman! the late American physicist Richard Feynman described how he amused himself by cracking open the safes at Los Alamos, which stored design papers for the Manhattan Project. He started out picking locks, which he describes like this: Now, if you push a little wire gadget —

The world has a new youngest grandmaster

Abhimanyu Mishra became the world’s youngest grandmaster last month, at 12 years and 4 months old. The boy from New Jersey achieved the milestone by scoring 7/9 at the Vezerkepzo GM Mix event in Budapest last month. In doing so, he has broken the record set almost 20 years ago by Sergey Karjakin, who became

Firestarter

It’s a joy to watch a player like Shakhriyar Mamedyarov, who can light a fire with his bare hands. Where most are content to develop their pieces in the opening moves, he has a knack for igniting the play at the slightest provocation. In the game below, Caruana’s move 9 h3 looks unremarkable, but Mamedyarov

How to lose

Millions of people would see losing to Anand as a privilege rather than a disgrace. So it is simply astonishing that one lucky opponent, facing the Indian star in an online simultaneous display, squandered the opportunity by cheating. ‘Checkmate Covid, celebrity edition’, hosted earlier this month by Chess.com, was supposed to be a lighthearted event,

Macaques and defence

January normally brings cheerful photos from the Gibraltar Chess Festival, where visiting chess-players get an impromptu snap with the Barbary macaques which inhabit the island. Alas, the 2021 festival was off, while the Fide Women’s Grand Prix, a 12-player all-play-all which forms part of the Women’s World Championship cycle, was planned for January and then

The back-rank mate

Compared with Anastasia’s mate, or an epaulette mate, the humble back-rank mate is named without imagination or whimsy. It is the Ronseal of mating patterns, administered by a rook or queen to a hapless king stuck on the rank behind its own pawns. But there is a rich variety of tactical motifs which culminate in

Hybrid chess

Chess was played by cable in the 19th century because… well, why not? And because everything old is new again, 2021 has brought us ‘Hybrid chess’, in which players play online, but congregate in hubs shared with other players under the supervision of an arbiter. This time, put it down to human frailty and our

Daredevil kings

The fifth match game between Potter and Zukertort, played in London in 1875, saw a dogged struggle. The final position is shown in the diagram below, where the players agreed to a draw after 91 Kb5-c4. William Norwood Potter, an English master, must have reasoned as follows: the protected passed pawn on d4 obliges the

Indian variant

Modern chess includes a panoply of ‘Indian’ openings, which share a common root in the starting moves 1 d4 Nf6 and include the King’s Indian, Nimzo-Indian, Queen’s Indian, Bogo-Indian, and Old Indian. But before 1900, the prevailing wisdom held that it was advisable for Black to contest the centre with a pawn advance. So the

What’s it worth?

The rule of thumb for weighing up piece exchanges says that pawns are worth one, knights and bishops three, rooks five and queens nine. It is such a useful guideline that one can go a long way without ever questioning it, but strong players have a feeling for the limitations. The first diagram shows a

Dead brain cells

As round 14 of the Candidates tournament unfolded, I had the feeling of watching an anti-climactic post-exam bender. Ian Nepomniachtchi had already passed with distinction, wrapping up tournament victory with a round to spare. The Russian plays energetic chess, but part of his success in Yekaterinburg was surely attributable to tempering his impulses throughout the
