his position comes from the game GM Artyom Timofeev (2570) vs GM Urii Eliseev (2582), Moscow Open 2016, round 7, played May 2, 2016. 

 

   In the position on the right it is White to move. 

 

   Answer below.

   As you can see from the diagram, both sides have two Queens, which is very unusual!

   Although Eliseev lost this game, he ended up winning this prestigious tournament on tie-breaks.

   Sadly, Eliseev (Russian: Юрий Михайлович Елисеев), died just a few weeks ago on November 26, 2016 at the age of 20 after falling from a balcony on the 12th floor of a Moscow apartment block. 

   From Wikipedia (https://en.wikipedia.org/wiki/Yuri_Yeliseyev_(chess_player)): His death was reported by his friend and fellow Grandmaster Daniil Dubov, who said that Yeliseyev had been trying to climb from a window to the balcony but slipped. Yeliseyev's flatmate told Russian TV that the parkour enthusiast "Yuri loved extreme things" and had climbed between the window and the balcony before.

   Here is an article from the BBC about his death, http://www.bbc.com/news/world-europe-38129713

   Rest in Peace.

   Answer:

   White played 48. Qxe5!! sacrificing both Queens at the same time!

   Dana Mackenzie wrote, "I can imagine a composed problem with two simultaneous queen sacrifices, but I would never have believed it possible in a tournament game."

   If Black plays 48...Qxe5 49. Qxf7#

   If Black takes the other Queen with 48...Rxg8 it is mate in three with 49.Qb8+ Qc8 50.Qxc8+ Qd8 51.Qxd8+

   The best Black can do is delay checkmate, with a variation like 48...Qd5 49.Qb8+ Qed8 50.Bxd5 Qxb8 51.Qxf7+ Kd8 52.Be6+ Qd6 53.Rxd6+ Bxd6 54.Qd7#
