2019 Gibraltar Masters - Round 10 - 31 January New Vlad Conquers the Rock



John Saunders reports: As they probably don’t say in Russian, “as one Vlad closes, another Vlad opens”. The old Vlad (Kramnik) won everything worth winning in chess, except the Gibraltar Masters, before bringing down the curtain on his chess career the other day. By contrast, the new Vlad (Artemiev) hasn’t won anything of note... until today, that is, when he won the Gibraltar Masters, and in the most accomplished style in a last round that featured wins for the lower-rated player on all three of the top boards.
I should get the day’s headlines out of the way before trying to assess the magnitude of today’s results. 20-year-old Russian grandmaster Vladislav Artemiev, overnight leader, completed a brilliant victory in the final round of the Gibraltar Masters, played at the Caleta Hotel, after defeating the fourth seed Yu Yangyi (China) in his last game to reach an unassailable score of 8½ points out of 10 and obviate the usual need for a tie-break. The young Russian, who was making his debut on the Rock and only three-months married, takes home the winner’s cheque for £25,000. Artemiev’s score of 8½ has only been bettered once in the history of this tournament by Vassily Ivanchuk when he scored an amazing 9/10 in 2011, and it has been equalled only a couple of times.
The destination of the £20,000 second prize was an even bigger shock, going to the 19-year-old Indian grandmaster Karthikeyan Murali, rated 2570 and seeded only 49th in the tournament pecking order, who finished with a sensational win against the tournament number one seed, Maxime Vachier-Lagrave, to finish on 8 points. The top women’s prize of £15,000 went to former women’s world champion 27-year-old Tan Zhongyi of China who won her final round game to finish on 7 points.
Artemiev’s success was absolutely deserved, by any yardstick you choose to apply. He played five of the top-rated six players in the tournament and achieved a jaw-dropping TPR of 2941. Those of us old enough to remember will find ourselves thinking back to 17-year-old Alexander Morozevich’s performance at the London Lloyds Bank tournament of 1994 when the Russian player scored 9½/10 for a TPR of 2970. Artemiev’s score and TPR may fall slightly short of Morozevich’s but the opposition in Gibraltar was significantly higher rated than in London in 1994.
Artemiev’s last-round win with Black against a seasoned tournament competitor as tough as Yu Yangyi had more than a touch of Carlsen about it, and I mean the Carlsen of a few years ago when he regularly ground super-GMs into dust from seemingly innocuous positions. The opening was an advanced (3.e5) Caro-Kann but soon departed from known lines. Engines preferred White for a while, perhaps based on the awkward gash in Black’s kingside. Artemiev’s queenside knight went on a curious tour, returning to its original square before penetrating as far as a2 before settling on b4 where it started to exert an influence on the game. Artemiev then sacrificed a pawn for more queenside pressure, whilst also setting up alternative ideas of attacking on the kingside. Eventually he latched onto a position slip by Yu Yangyi and caught his opponents’ two knights flat-footed and getting in each other’s way. Yu Yangyi jettisoned his extra pawn to try to get back on level terms but Artemiev was relentless, won a pawn and outmanoeuvred his opponent to secure victory. It was a real tour de force, or maybe that should be tour de horse.
Round 10: Yu Yangyi (2764) - Vladislav Artemiev (2709)
1.e4 c6 2.d4 d5 3.e5 Bf5 4.Nf3 e6 5.Be2 Nd7 6.0‑0 Bg6 7.c3 Nh6 8.a4 a5 8...Rc8 was played in the game Adams-Conquest, British Championship 2010, but didn’t work out too well for our much-loved tournament director. 9.Na3 Exiting the book, but maybe this is a theory-lite system anyway. 9...Be7 10.Nc2 0‑0 11.Nce1 c5 12.Bxh6 gxh6 13.Bb5 cxd4 14.cxd4 Nb8!? The equivalent of football’s Cruyff turn, where the player on the ball turns back suddenly and tries to go round the defender a different way? 15.Qd2 Kg7 16.Nd3 Around here engines much prefer White, unless you leave them to search a bit long when they calculate that Black’s positional weakness on the kingside is less serious than it looks. 16...Na6 17.Nf4 Qb6 18.h4 Rfc8 19.Rfc1 Rxc1+ 20.Rxc1 Nb4 21.g3 Na2! Overlooked by engines, this move is simply designed to evict the white rook from the c-file to allow his own rook to occupy it. 22.Rd1 Rc8 23.Nh2 Qc7! Better than the tempting 23...Rc2?! when 24.Qe3 sets up the threat of Nxg6, Ng4 and an invasion on h6. 24.Bd3 h5 A necessary precaution to prevent the h2 knight coming to g4. Black probably realised he was losing a kingside pawn but was banking on his queenside pressure being sufficient compensation. 25.g4 Nb4 26.Bxg6 If 26.Bb1 hxg4 27.Nxg4 Bxb1 28.Nh5+ Kh8 29.Rxb1 (29.Qh6 fails to 29...Rg8 30.Nhf6 Qc2) 29...Qc2 and the position greatly favours Black. 26...hxg6 27.gxh5 White has his extra pawn but Black now starts his queenside counter. 27...Qc2 28.hxg6 Qf5 29.Qe3 Maybe White should take his chances with 29.gxf7!? Bxh4 which gets messy, with kingside threats for Black in the air, but shouldn’t be worse for White with best play. 29...fxg6 30.Qg3 Rf8 31.Ng2 Qc2 32.Ne3 Qe4
After the shadow boxing of the last few moves, White miscalculates. Instead 33.Ng2 is fine. Perhaps White thought his extra pawn was worth trying to exploit. 33...Nc6! Black switches focus onto the d4–pawn. 34.Qe3 Rf4! 35.Nf6 35.Qxe4 Rxe4 is even worse with the d4–pawn lost and the h4–pawn also in danger. White is obliged to cash in his extra pawn to try and right his ship. 35...Bxf6 36.exf6+ Kxf6 37.Qxe4 Rxe4 38.Nf3 Ne7! This wonderful knight is on the move again, this time to menace the d4 and h4 pawns simultaneously from f5. 39.Kg2 Nf5 40.Rd3 Nxh4+ Its job well done, the knight leaves the board with its master very close to being £25,000 richer. 41.Nxh4 Rxh4 42.Kg3 g5 43.Kg2 After 43.Rf3+ Kg6 44.Re3 Kf5 White is no better off. 43...Re4 44.Kg3 Kf5 45.Kg2 g4 46.Kf1 b6 47.Kg2 Re1 48.b3 Ke4 49.Rd2 Rb1 50.Kg3 White can chase the king back with 50.Re2+ Kf5 51.Re5+ Kf6 but it makes no difference as his pawns drop like ripe apples. 50...Kf5 51.Rd3 Rh1 52.Kg2 Rh3 0‑1 53.Rxh3 gxh3+ 54.Kxh3 Ke4 is an easily won king and pawn endgame.
Much the same comments apply to second-placed Karthikeyan Murali who was an unknown in chess circles outside India before playing in Gibraltar. Karthi (as he’s known to his friends and, soon, the chess world) started slowly with two draws and lost a game to four-times winner in round five, but finished with an astonishing burst of five wins from his final five games, all against seasoned grandmaster opposition. Many strong players from India have taken part in the Gibraltar tournament, including the legendary world champion Viswanathan Anand, but none of them have matched Murali’s fine score of 8 points.
