WORLD CHESS CANDIDATES 2018 BERLIN – ROUND 14


This year in November an American chess player will contest a World Championship match for the first time since that famous event in Reykjavík during July and August 1972.

There was one aspect of Caruana’s play today that caught me completely by surprise. When Mamedyarov finished his game Caruana only needed a draw to secure his spot in the World Championship match and a guaranteed large payday. Yet he has a winning position on the board and Grischuk was down to 4 minutes on the clock. Many players, me included, would have offered the draw and take the tournament rather than risk it all by pressing on. What would you have done?

Aronian vs So was the first to finish. It was a Symmetrical English. This was the only game that had zero impact on the top spot in the tournament. The handshake came at only 17 moves.

The second game of the day was a Closed Ruy Lopez between Karjakin and Ding. Ding needed to win the game to have any chance of qualifying. So it was really surprising for him to take a draw in an almost winning position. By taking the draw karjakin needed both Mamedyarov and Caruana to both lose their games.

Then was Kramnik vs Mamedyarov, an Open Catalan. Nothing unusual seeing Kramnik bring out his trusty Open Catalan in a crunch game.  The draw guaranteed second place for Mamedyarov, unless Caurana somehow managed to lose against Grischuk.

The final game was a Petroff between Grischuk and Caruana. I’ll admit that I was very surprised to see Caruana choose the Petroff in a game where he had to win to have full control over his tournament outcome. Yet somehow it all worked out for him.

Hopefully we get to see some fighting games in November rather than the sawdust that Karjakin brought to the board two years ago. In a way it is a relief that none of the Russian players won. Having a team of Russian players and officials in London in November would have been rather awkward to say the least.

Here are the games from round 14:
