The FIDE World Cup is in full swing in Russia - 128 players started in this knockout tournament, but after the first three rounds most of them - including World No 4 Anish Giri - had to pack their bags.
Just 16 players continue to compete for the first prize of $110,000 and two places in the next Candidates tournament.

Among those 16 players is Russian GM Peter Svidler, who is already well-known to Irish chess fans for winning the Bunratty Masters twice back-to-back.
In the starting round he produced the following entertaining game:
Svidler - Albornoz Cabrera
1.e4 c5 2.Nf3 Nc6
3.Bb5 d6 4.0-0 Bd7
5.Re1 Nf6 6.c3 a6
7.Bf1 Bg4 8.d4 Bxf3
9.gxf3 cxd4 10.cxd4 d5?!
Black starts a fight for which he isn't quite ready. The young Cuban GM should have opted for 10...g6.
11.e5 Nh5 12.e6
Maybe this move was too hasty and White should have preferred 12.f4 g6 13.f5!.
12...g6 13.Nc3 f5?!
It was too dangerous to leave the enemy pawn on e6 - Black would have a much safer position had he played 13...Ng7!? 14.Bh3 Qd6! 15.exf7+ Kxf7 16.Na4 e6.
14.Qb3 Nxd4 15.Qxb7 Rb8?!
It was better to play 15...Bg7.
16.Qxa6 Nxf3+ 17.Kh1 Qc7?
Trying to create his own threats, Black missed the last chance to play 17...Bg7 - after 18.Qc6+ Kf8 his king would be in a much safer position.
18.Qa4+ Kd8 (D)
Both kings are in danger, but White is first to strike:
19.Bf4! Nxf4 20.Nb5! Qb6
