In the first game of the match Wei Yi delighted his fans with a spectacular attack, in game two Richard Rapport countered with a convincing technical win.
In game three the young Hungarian again showed strong positional chess. With Black he tried the rarely played but interesting Tartakower Variation of the Caro-Kann and obtained a clear advantage in a queenless middlegame. But he missed a good chance and allowed Wei Yi to build a fortress in a minor piece ending which secured the draw.
Wei Yi has White in game three but fails to find a recipe against Rapport's opening.

In game four Rapport repeated the Trompowsky from game two but this no longer caught Wei Yi by surprise. A spectacular opening led to an endgame with opposite-colored bishop in which Wei Yi had some pressure but not enough to overcome Rapport's defence.
After four games the score war 2-2 and a blitz-tiebreak with a time-limit of 5+3 had to be played. But after two games this tie-break ended with another 1-1 tie and an Armageddon game had to decide. Rapport won the Armageddon and the match.
All in all this win was deserved: in games two and three Rapport outplayed Wei Yi, and in the first game, which Wei Yi won, Rapport had a good position but tried too hard and lost. In game one Wei Yi showed his attacking skills but all in all the 17-year old Chinese seemed to be slightly worse.
