Hikaru Nakamura scores a hat trick

Photos by Eugeny Atarov

Hikaru Nakamura won the Zurich Chess Challenge for the third time in a row, although it was no stroll in the park. Going into the last round, Nepomniachtchi was trailing Hikaru by just half point. Hikaru had the better Sonneborn-Berger score even if Nepomniachtchi was to catch up.

He made a solid and comfortable draw against Vishy and secured his championship.

Hikaru continued to be in his element and was undefeated throughout. Although there were a few rare moments when his opponents had chances, overall he was too fast, too strong.  He started off with a couple of victories over two of the lower ranked players in the tournament – Yannick Pelletier and Grigory Oparin. He was particularly brutal against Grigory.

He then just won one more game from the next five against Vlad, but that was more than enough for him to coast through to the championship comfortably.

Nepomniachtchi would have still liked to catch up with Hikaru and become the joint winner, but he couldn’t get past Grigoriy in this game.

Vishy continued from where he had left, with a solid performance. He was firm with black, and took his opportunity against Yannick.

With the White pieces, he continued to play like in his olden days, sticking to 1.e4. He managed to play fast and maintain a decent level, and when his opponent’s made mistakes like 19…h5 in the following game, it took him only a few seconds to pounce savagely.

The final blitz was of a much better quality than the opening blitz. Apart from the fact that the players had warmed up, the time control was also much higher – 10+5. In the ‘new classical’ version, initially the quality of play was impacted by time, but the play only got better as the tournament progressed.

I think this sort of reduced time control should be experimented more with and would be especially ideal for events that are traditionally organised with two rounds per day, a format that is held in many parts of the world.
