A day of short draws

Three out of top six boards ended in draws in less than 25 moves. It is quite understandable that everyone wanted to save energy for the following day as it has the tournament's second double-rounds. Only four games were decisive among the top ten boards, and white won them all.

Hakobyan - Puranik: 1-0

Aram Hakobyan (ARM) beat Abhimanyu Puranik to take the sole lead.

Position after 29..Rc5

29...Rc5 seems like a good way to generate some counterplay, but it actually does the opposite, White gets a good opportunity to attack on the kingside. Find out what Black could have done instead.

Praggnanandhaa - Pavlov: 1-0

Praggnanandhaa defeated IM Sergey Pavlov (UKR) with a showcase of positional play.

Position after 20.Rxd4

White aimed for the backward d7-pawn which became the deciding factor for the rest of the game.

Gukesh - Haldorsen: 1-0

Gukesh defeated IM Benjamin Haldorsen (NOR) after the latter made both positional and tactical mistakes.

Position after 25...Nce4

The idea behind 25...Nce4 is simple, Black wants to bring a knight to the c3-square. So 26.Bxe4 is quite logical, now Black should have recaptured with the knight, 26...dxe4 was not such a good idea. 27.Ndxe6 fxe6 gives Black a double-pawn on the e-file and the hopes of getting the knight to c3 is gone. Soon Black made a tactical error which cost him a pawn and eventually blundered the knight before resigning.
