Last year Magnus Carlsen and Anish Giri tied for first in the Tata Steel Chess Tournament, and in this year's edition they are once again the only contenders for first. Last year, Carlsen defeated Giri in a playoff; this year, a playoff is impossible, as Carlsen enters the round half a point ahead of his rival and they face off in the last round. (I suppose one could consider it a de facto playoff: an Armageddon game with a classical time control. If Carlsen wins or draws, he wins the tournament; if Giri wins, then he does.)
They entered the round tied for first after Giri got a colossal gift from Sam Shankland, who resigned in a completely drawn position. In this round Giri got a second gift, as Teimour Radjabov offered a draw (which was of course accepted by Giri) in a won position. Not a dead or obviously won position, but a winning one all the same. Even with all the freebies Giri is enjoying, Carlsen still enters the last round as the sole leader after grinding out a victory against Jan-Krzysztof Duda. No freebies, just hard work: he obtained an advantage in the early middlegame and never let go. Duda didn't make it easy for him, but he was still forced to surrender after 71 moves.
Ian Nepomniachtchi entered the round only half a point behind the leaders, but now he's a point and a half behind after getting clobbered by Shankland. Perhaps trying to hard to get a complicated and untheoretical position Nepo played an experimental line, a Pirc with ...e6. The combination of ...g6, ...Bg7, ...Nf6 and ...e6 generally don't go very well together (to oversimplify a bit: if you want to play a Pirc, avoid ...e6; if you want a Hippo, don't play ...Nf6), and they went dreadfully wrong in this game. Shankland played natural, healthy, aggressive chess, and won convincingly.
Ding Liren and Viswanathan Anand could have remained a point behind Carlsen, had either defeated the other. That still would have left them mathematically eliminated from the race for first, after Carlsen's win, but at least they'd be a bit closer. It was a very good game, with Ding playing 1.e4 - an unusual first move for him - and having some deep preparation. Anand defended well, and 28...Rd6 was a beautiful idea that led to an ending where White's had no way to use his material advantage.
Finally, Vladimir Kramnik made it two consecutive wins by defeating Vladimir Fedoseev in a queen and rook ending, while Shakhriyar Mamedyarov bled some rating points by drawing with Jorden Van Foreest. Kramnik is now "only" -18.7 for the touranment, while Mamedyarov is a ghastly -26 on the live rating list. And Santosh Vidit Gujrathi was winning against Richard Rapport, but after he missed the right way to prosecute his attack the game finished in a draw.
The tournament site is here, the games (with light comments, though not about photons) are here, and these the pairings for the final round, tomorrow:
- Giri (8) - Carlsen (8.5)
- Nepomniachtchi (7) - Radjabov (6)
- Kramnik (4.5) - Shankland (5.5)
- Mamedyarov (4.5) - Fedoseev (4.5)
- Rapport (5.5) - Van Foreest (4.5)
- Anand (7) - Vidit (6.5)
- Duda (5) - Ding (7)
In the Challengers Tournament, the sole leader is Vladislav Kovalev, who came into the event as the second seed. He has 9/12, good for a half-point lead over 16-year-old Andrey Esipenko and Maksim Chigaev. Unfortunately for Chigaev and Esipenko, they're both playing Black against strong opponents (Gledura and Bareev, respectively) while Kovalev has White against bottom seed and co-cellar dweller Stefan Kuipers. One never knows for sure, but the odds of Kovalev's getting clear first and securing qualification to next year's top group look awfully good.
