The results of round 4.1. Only 16 players remain at the World Cup 2019

Duda played highly enterprising chess to beat Jeffery Xiong!

Duda sacrificed a piece and put a lot of pressure on Xiong. For quite some time the position was dynamically balanced. Black's last move ...g5 was a mistake. How did Duda take advantage of it?

e5! That's the right way! fxe5 is not possible. And after dxe5 White queen swooped in with Qa7 and it was all over! The knight, queen and the d-pawn form a deadly trio.

In the game between two world class players, MVL managed to beat Peter Svilder!

Svilder is a great sport. He doesn't mind to analyze his game even though he has lost it.

MVL vs Svidler

Black is coming in threatening Rg6+ How did MVL defend?

You can stop the rook from coming to g6 by playing Bd6. But that simply loses the game to Qg6+. Hence MVL had the very strong f5! and after Qxf5, he went Bd6. The point being that the bishop can now sit back safely on g3.

Vitiugov managed to spring the surprise of the day by beating Wesley So

There was definitely something to learn from Grischuk's play in the endgame. He ground out a win from a completely equal position!

Grischuk vs Dominguez

In this position Black played the move c2, but it lost as after f6+! White pushed the king back and then captured the c2 pawn with an easy win. Black actually could hold the endgame with ...Bg5, but the defence was not at all easy as it involved getting the king to f8, allowing the pawn to advance to f6 and then rerouting the bishop from e3 to c5. You can find the detailed analysis in the replayer below.
Grischuk was tired after a long game, but it is always a pleasure to hear him in an interview!
