Right after the world rapid championships, the world blitz tournament took place in chess-conscious St. Petersburg (Russia). All participants of the previous tourney participated in the $150,000, FIDE Swiss system event.
Norwegian world champion Magnus Carlsen, who finished a disappointing fifth in the world rapid, bounced back and captured first this time to retain his title. He was undefeated, scoring 17.0 out of a possible 21.0. What’s more, winning St. Petersburg brought Carlsen’s record to two world title year-ending victories. He successfully defended his world championship crown against American challenger, Fabiano Caruana in London last November, not to mention keeping the No. 1. spot in the world chess rankings. The year 2018 was truly a Carlsen year.
Jan-Krzystof Duda, Poland’s brightest hope at 20, finished second, half-a-point behind the winner, while grand chess tour champion Hikaru Nakamura (USA), wound up third with 14.5 points.
Tied for fourth-seventh at 14.0 apiece were Peter Svidler (Russia), Levon Aronian (Armenia), Ian Nempomniachtchi (Russia) and Gata Kamsky (USA).
In the women’s championship, Russia’s top gun Kateryna Lagno, had to be around to assure the host’s creditable showing. Eventually, Lagno emerged sole winner, with an unblemished 13.5 points out of 17.0, one half point ahead of runner-up Sarasadat Khademalsharieh of Iran and a full point over third placer Lei Tingjie of China.

6. Nbd2 ....
After 6. cxd5 cxd5 7. 0-0 Nc6 the game is probably equal.
6.... O-O
7. O-O a5
8. b3 Ne4
9. Bb2 Bf5
Many moves have been tried for Black, but 9...a4 and 9....f5 are the most frequently encountered alternatives.Now comes middle game maneuvers for initiative.

18. Rac1 Nf6
19. Bf3 a4
20. Qe3 ....
After 20. Ba3 Re8 21. Bb4 axb3 22. Qxb3 Qb6, the position seems to be about even.
20.... Qd7
21. Rc2 axb3
22. Qxb3 Rac8
23. Rfc1 Bh6
24. Rxc8 Rxc8
25. Rc5 ....
The immediate 25. Rxc8ch is preferable, according to the engine.
25.... Bf8
26. Rb5 ....
Ceding the open c file to Black, who makes good use of it throughout. Hence 26. Rxc8 was necessary.
26.... Rc7
27. Rb6 Ne4
28. Bxe4?! ....
Exchanging the only piece protecting the White King seems premature at this point. Correct is the engine’s 28. Qe3.
28.... fxe4
29. Kg2 Bg7
30. Rb5? ....
The start of White’s ineffective maneuvering, spoiling his chances of survival. The passive 30. Qd1, to defend White’s Kingside, was in order.
30.... Qf7!
After spending most of the game on the Q-side, Black suddenly shifts his forces to the other wing, and White cannot adjust fast enough to the switch.
31. Rb6 Bh6!
The quiet but powerful manner Black’s attack is building up is pleasant to follow. The text secures e3.
32. Qd1 Be3
33. Qf1 Qh5!
The winning move, as the threat of 34....Rf7, followed by 35...Rf2ch is indefensible.
34. Rxe6? ....
This loses material, but White has no good reply. For instance 34. Rb3 Rf7 35. Qxf7ch Kxf7 36. Rxe3 b5 37. Kg1 b4, and Black should win handily.
34.... Rc2!
34...Rf7? allows White to escape with 35. Rf6! The text wins a piece by forced.
35. Kh1 Rxb2!
This is the end. Not 35...Rxe2? when 36. Re8ch! Qxe8 37. Qxe2 gives White some hope of survival.
36. Re5 Qf7!
Although Black is a piece ahead, he must play very well. Not 36....Qxe2? because of 37. Re8ch!
37. Rf5 Qe6
38. Re5 Qd7
39. Qf6 ....
39. Rf5 Kg7 40. Rf8 Qe6 offers no hope for White.
39..... Rb1ch
0-1
The rest of the story would be 40. Kg2 Rg1 mate.
