World Cup: Ivic stuns Andreikin, Carlsen advances

Esipenko paired up against Carlsen

Five players moved on to the round-of-16 after knocking out their opponents in the first set of rapid tiebreakers on Saturday. In a massive upset, Serbian GM Velimir Ivic (2581) got the better of 2013 World Cup runner-up Dmitry Andreikin (2724) to secure a spot in the fifth round, where he will face an in-form Vladimir Fedoseev.

Ivic beat his higher-rated opponent with black in the first rapid encounter from a highly complicated ending.

Magical Chess Endgames Vol. 1 & 2 + The magic of chess tactics

In over 4 hours in front of the camera, Karsten Müller presents to you sensations from the world of endgames - partly reaching far beyond standard techniques and rules of thumb - and rounds off with some cases of with own examples.

As GM Karsten Müller shows below, White could have held a draw from this position, as his passed pawns can neutralize Black’s knight and passer on the a-file. Andreikin would have needed to be very precise, though!

Other matches that finished after two games in round-4’s playoffs:

• Magnus Carlsen knocked out Radoslaw Wojtaszek
• Etienne Bacrot knocked out Pavel Ponkratov
• Alexander Grischuk knocked out Anton Korobov
• Peter Svidler knocked out Nikita Vitiugov

The remaining matches were decided in the second set of tiebreakers (10-minute games with 10-second increments):

• Andrey Esipenko knocked out Daniil Dubov
• Vasif Durarbayli knocked out Nodirbek Abdusattorov
• Sergey Karjakin knocked out Vladislav Artemiev

There were no draws in the match between Durarbayli and Abdusattorov, with the latter bouncing back in the classical phase and then grabbing the lead in the rapid tiebreakers — the young Uzbek found a good-looking mating attack with the white pieces.

Master Class Vol.14 - Vasily Smyslov

Smyslov cultivated a clear positional style and even in sharp tactical positions often relied more on his intuition than on concrete calculation of variations. Let our authors introduce you into the world of Vasily Smyslov.

Black resigned after 43.Ra8+ due to 43...Bxa8 44.Nc8+ Ka6 45.Rb6#.

Unfortunately for Abdusattorov, though, not only did Durarbayli won the next game on demand but also scored back-to-back victories in the 10-minute encounters to get a spot in the round-of-16.

GM Müller analysed Abdusattorov’s remarkable win.

As has been mostly the case throughout the women’s event, the rating favourites prevailed in Saturday’s playoffs:

Fundamentals of Chess Openings

Starting out in chess is difficult, and this DVD aims to reduce that stress. Designed for beginner levels in openings, a brief introduction to the reasons we play some of the most common moves in popular openings like the Spanish and Sicilian is given.

• Aleksandra Goryachkina knocked out Antoaneta Stefanova
• Dinara Saduakassova knocked out Alina Kashlinskaya
• Nana Dzagnidze knocked out Polina Shuvalova
• Kateryna Lagno knocked out Bibisara Assaubayeva

Assuabayeva was the most surprising player that made it to the round-of-16 in the women’s category, but she had the tough task of facing Lagno. The Russian star won the first rapid tiebreaker with black — she converted her advantage into a win from a technical position in which she had the wrong rook’s pawn.

Despite having a large material advantage, converting this with black is not trivial at all. In fact, Lagno barely managed before the 50-move rule would have granted her young opponent a draw. GM Müller annotated the endgame.
