Both Ding Liren (China) and Teimour Radjabov (Azerbaijan) won their white games on Tuesday to reach the semifinals of the FIDE World Cup <khantymansiysk2019.fide.com/>. Ding knocked out Alexander Grischuk (Russia) who went astray in time trouble, while Radjabov came out on top in a complicated Gruenfeld against Jeffery Xiong (U.S.).

Early in the tournament, Radjabov said in an interview that he was basically waiting for a bad result to come. The 32-year-old grandmaster from Azerbaijan didn’t arrive to Khanty-Mansiysk with a bucket full of confidence, mostly because he hasn’t been very active in recent years.
Few chess fans who filled out a fantasy bracket will have put him in the semifinals, but that’s where he is right now. In a sharp Gruenfeld, Radjabov played strongly and knocked out the 18-year-old Xiong from Plano, Texas.
“For sure I surprised him in the opening,” Radjabov said. “I guess he didn’t look at this line today because there are so many lines I am playing as well, and recently all the players are playing a lot of lines so it’s not easy to prepare.”
He was referring to his choice on move seven, one of the main crossroads in this opening. Key moves are 7.Nf3, 7.Be3 and 7.Bc4, but Radjabov’s 7.Bb5+ is a respectable system as well, which tries to prevent Black from getting his typical …c5 break.
Indeed caught in unfamiliar territory, Xiong erred with 14…Rd8?! and after 15.f5! he was under serious pressure.
After the trade of dark-squared bishops, Radjabov felt he was much better, as he was told by the Baku school of chess.
“You know, we see the king there, the bishop is absent from g7, everything is coming, f6, Qh6 stuff,” said Radjabov.
Radjabov thought for 14 minutes here and decided to follow his Azeri attacking instincts. He went 17.Qd2 to play for mate (“like in my childhood”—Radjabov) but completely missed 17…Nc4.
“I was really upset; I really didn’t see the way to proceed,” said Radjabov, who saw his advantage slipping away. Still, he decided against a move repetition.
“There was a way to take the draw,” he said, “which would be the sane thing more or less because just trying your luck in rapid or classical games, there is no huge difference, somewhere you’ll lose or win. So why not today, I thought.”
“Honestly it was a very complicated game, maybe one of the most complicated games I’ve played recently,” said Radjabov. “I’m certainly happy to emerge as the winner in this situation because it didn’t seem to go my way at some point. I thought I lost thread and he’s playing well. I had my doubts there. At some point I thought that maybe if the good moment comes I’ll take a draw but actually I think he was the last to make a mistake. This is what decides the high-level matches.”
The top seed also managed to avoid tiebreaks. Ding defeated Grischuk with the white pieces as the Russian grandmaster once again got in severe time trouble. He managed to reach move 40, but by then his position was lost.
“Of course I’m happy about the result but maybe he didn’t play so well and he made many mistakes in time trouble,” Ding said.
He thought his opponent initially played well.
“The position was equal but I was the one who was pushing for the advantage,” said Ding. “Then he played too passive in time trouble.”
In his explanation after the game (see the annotations in the game viewer) Ding suggested alternatives for Black on move 25, 26 and especially 29.
Like Radjabov, the Chinese number-one is now one match victory away from reaching the 2020 Candidates’ Tournament—a big bonus for both World Cup finalists, if not their main goal.
The game between Vachier-Lagrave and Aronian was over after just 40 minutes. The Armenian GM repeated the 6…d5 line in the Italian, a move with which he had beaten Maxim Matlakov in the third round and which had been played already four times in this World Cup.
MVL, on his turn, repeated his 14.Qe2 move, which was a novelty when he used it to beat Dmitry Jakovenko in the tiebreak of the third round. Radjabov then borrowed it in one of his draws with Shakhriyar Mamedyarov in the next round—that’s how fast theory develops these days!
Aronian had done his homework, and in no time a dead-drawn endgame was reached. With only opposite-colored bishops the players blitzed out some more moves to reach move 30, when a draw offer was allowed. (The final position is almost symmetrical but somehow White has lost a tempo!)
