Superbet: Mamedyarov in the sole lead

A full-point lead

For the first time in Bucharest, three games finished decisively in a single round. While Levon Aronian and Anish Giri scored their first victories of the event, both to bounce back to a fifty percent score, Shakhriyar Mamedyarov obtained his third full point in a row to go into the last two rounds a full point ahead of the field.

The first game to finish decisively on Saturday was Aronian’s win over former co-leader Alexander Grischuk. Teimour Radjabov and Wesley So — both undefeated so far in the event, with Radjabov having signed seven draws so far — agreed to a 38-move draw meanwhile. These two results meant Mamedyarov would get a 1-point lead over Grischuk and So if he managed to beat Fabiano Caruana with the black pieces.

These DVDs are about Understanding Middlegame Strategies. In the first DVD dynamic decisions involving pawns are discussed. The second DVD deals with decision making process concerning practical play.

Caruana was struggling against the Azerbaijani’s bold opening choice, but once he found himself in a clearly inferior position he started to defend tenaciously, giving up two pawns to sharply complicate Black’s task. Eventually, Mamedyarov got to convert in the rook endgame a pawn to the good, climbing to the top stop in the standings table and gaining enough rating points to reach fifth place in the live ratings list.

The second-to-last game to finish was Giri’s victory over Maxime Vachier-Lagrave. The Dutchman managed to convert an opposite-coloured bishops endgame with an extra pawn. Giri confessed:

The more experienced I get, the more I realize chess is just about luck, there is really nothing else.

In the duel between Romanians, Bogdan-Daniel Deac tried hard but could not convert from a slightly superior endgame against Constantin Lupulescu. The players agreed to split the point after 75 moves — no short draw in the Romanian derby!

Two of the most fighting players in the elite predictably went for a sharp struggle from the get go. Caruana played the 4.d3 Anti-Berlin with white, while Mamedyarov did not hesitate to play his trademark move when given the chance.

9...g5 was a novelty, and one that discombobulated Caruana — one of the best theoreticians in the world. The American did not find the best response, as he spent a bit over three minutes on 10.Ne2 when 10.Nd5 was the way to go. The idea is that after 10...Bd7 White has 11.Bxg5 with a big advantage; thus, Black would need to play 10...h6, and White is more than fine.

In the game, Black advanced his g-pawn all the way to the third rank, getting attacking chances even after the queens left the board.

Evans Gambit for the new generation

The Evans Gambit is an attempt to destroy Black in gambit fashion straight out of the opening. Featuring games of old, and numerous new and exciting ideas, this DVD will give you a genuine and more exciting way of playing the Giuoco Piano.

Mamedyarov was clearly the one with the initiative — 17...g3 18.Nd4 Bd8 19.fxg3 Rxg3 20.Re1 Rg4 21.Bg5 Bxg5 22.hxg5 Ke7 23.Rad1 Bd7

At this point, Caruana found two consecutive moves that were the first suggestions of the engines, giving up two pawns to get better defensive chances — 24.e6 fxe6 25.g6 hxg6.

In the post-mortem interview, Mamedyarov praised his opponent’s play in the last stage of the game, noting that, had he managed to save the draw, it would have been a brilliant defensive effort. However, it was not to be for the American, who thus suffered his second defeat in the tournament.

Much like Mamedyarov, who played enterprising chess from the get go, Grischuk showed one of his most salient features as a chess player: his proclivity to get into deep time trouble. Against Aronian, the Russian grandmaster faltered on move 21, when he already had less than five minutes on the clock.

Here Black needed to play carefully, as White might at any point get a strong kingside attack. The best moves in the position were 21...Re7 or 21...Ne5, trying to untangle. Instead, Grischuk erred with 21...Nd4, allowing White to play the forcing sequence 22.Nxd4 Bxd4 23.Rad1

The Art of the Exchange Sacrifice

People in Greenland can differentiate between 36 kinds of snow; the Swedish International Master Ari Ziegler will teach you to differentiate between 20 kinds of exchange sacrifice. His systematic approach to exchange sacrifices will rapidly enhance your understanding of one of the most exciting and difficult aspects of chess. Your widened horizon will help you to be able to follow the games of top GMs better and also to see more options in your own positions, which in turn will improve your chess results.

White has activated his pieces, while Black’s army is still struggling to find coordination. At this point, again, Grischuk needed to look for a way to relieve the tension with 23...Be5 and try to defend the position a pawn down that would ensue. His 23...Bc5, on the other hand, led to a quick defeat, as White went 24.Bb1 and soon advanced his pawn to e5, which allowed the light-squared bishop to decisively join the attack.
