Chess: Fabiano Caruana and Magnus Carlsen lead near the finish at Wijk

Chess: Fabiano Caruana and Magnus Carlsen lead near the finish at Wijk. Alireza Firouzja was in first place until the Norwegian and the American outclassed the 16-year-old when they met

Magnus Carlsen and Fabiano Caruana, the top two in the rankings who played an epic title match in London 2018, are poised to fight out the finish at Tata Steel Wijk aan Zee as the Netherlands elite event reaches its climax. Carlsen, the world champion, has surged with three straight wins following his slow start of seven draws.

After 10 of the 13 rounds Caruana (US) led on 7/10, followed by Carlsen (Norway) 6.5/10, Wesley So (US) and Jorden van Foreest (Netherlands) 6/10. Caruana has the easiest schedule as he meets the Belarus tailender Vladislav Kovalev in round 11, while So and Carlsen are paired in the final round.

The two leaders showed their class when in successive rounds they defeated 16-year-old Alireza Firouzja. The talented teen had captured the imagination of chess fans, first by his decision to quit Iran rather than accept its official ban on playing Israeli opponents and then by his controversial loss on time to Carlsen in the World Blitz in Moscow.

Carlsen’s win began with a Ruy López finesse, as he reached a standard position after Black’s 12th move – but with Black still to play. His unusual move order earlier had persuaded Firouzja to advance a2-a3 and then a3-a4 instead of in a single step. Then Carlsen used his strategic skills to gain control with his active bishops, Firouzja never created counterplay, and although Black’s conversion was inaccurate it was good enough to win.

Caruana’s victory was even more impressive since he took on Firouzja on his own territory, mazy tactics in the style of the legendary Mikhail Tal which the Iranian has used in hundreds of internet bullet and blitz games. The opening could be called a Six Pawns Attack against the sharp King’s Indian, and the game continued in this vein as Firouzja sacrificed a knight for several pawns. With the game still in the balance, he erred fatally at move 30 and Caruana pounced with a decisive attack.

Firouzja’s ranking briefly touched the top 20 during his winning run, and his results at age 16 compare with Carlsen’s, so his weekend rounds starting with another legend, Vishy Anand, on Friday will be critical in judging his response to the double setback.

While Wijk is nearing its end, the Gibraltar Masters, one of the world’s strongest opens, has just got under way. The top seeds Shak Mamedyarov and Maxime Vachier-Lagrave have already dropped half points.

China’s Ju Wenjun retained her women’s world championship on Friday when she defeated her Russian challenger Aleksandra Goryachkina by 2.5-1.5 in a rapid chess tie-break after their classical series, played in Shanghai and Vladivostok, was tied at 6-6. The prize fund of €500,000 was a record for the women’s title.

They were evenly matched, and the lead changed hands several times in a fluctuating contest. Ju Wenjun was more experienced in rapid chess and she won well in the decisive tie-breaker.
