Winning on demand

On top board, Magnus Carlsen could not win his match against Radoslaw Wojtaszek in the classical phase, as the world champion got a clearly superior position but failed to find the winning blow in the second sharp struggle of the match.

 

25.Rxh7 was the winning move, as after 25...fxg6 26.Qxg6 Black needs to part with his queen in order to avoid a quick mate. Surprisingly, however, the world champion missed this chance and played 25.Bc2. Wojtaszek managed to escape from what had been a miserable position after 25...Qf2 26.gxf7+ Kxf7 27.Bxf5 (27.Qe4 was stronger). A draw was agreed seven moves later.

Much like in the open section — but in a field of half the size — 2 players scored wins on-demand to take their matches to tiebreaks in the women’s section, as Aleksandra Goryachkina and Nana Dzagnidze won with white to level the score against Antoaneta Stefanova and Polina Shuvalova respectively.

 

Dzagnidze found 17.Bxh6 in the above position, and went on to score a remarkable 27-move victory over Shuvalova.

On the other hand, 4 players who came from drawing on Thursday scored wins in game 2 to secure a spot in the event’s quarterfinals:

  • Anna Muzychuk knocked out Elisabeth Paehtz (1½-½)
  • Alexandra Kosteniuk knocked out Mariya Muzychuk (1½-½)
  • Valentina Gunina knocked out Nino Batsiashvili (1½-½)
  • Tan Zhongyi knocked out Sarasadat Khademalsharieh (1½-½)

Endgame analyses by GM Karsten Müller

Looking at Friday’s games, our in-house specialist found 3 instructive positions that highly differ from each other. In the Russian duel between Andrey Esipenko and Daniil Dubov, the latter managed to hold a draw with knight and pawn against rook and pawn.

 

Details matter — GM Müller shows why Esipenko’s 69.Kd5 was not the most precise, while 69.Kd4 would have won the game with correct play in the ensuing position!

The remaining two positions see Elisabeth Paehtz failing to defend in a rook position against her friend Anna Muzychuk, and Nodirbek Abdusattorov activating his king to beat Vasif Durarbayli in an ending with rooks and bishops on the board.
