Malcolm Pein on…Shak’s Killer Combo

Shak Mamedyarov and Alexander Grischuk took control of the Grand Chess Tour’s Superbet Chess Classic in Bucharest with three to play. Mamedyarov produced an opening novelty and Levon Aronian went wrong immediately in a game I will analyse tomorrow. Grischuk overpowered Constantin Lupulescu in a complex Sicilian Defence Richter Rauzer where both kings were exposed.

Standings: 1-2 Grischuk & Mamedyarov 4/6; 3 So 3.5; 4-6 Deac, Caruana, Radjabov 3; 7-9 Giri, Vachier-Lagrave, Aronian 2.5; 10 Lupulescu 2.

Mamedyarov made his move in round five with this sparkling combination that blew away Lupulescu.

There had been a lot of manoeuvring and even a hint of a repetition after 32.Bf1-e2 Nf6-d5 33.Bf1 when Shak uncorked: 33…e5! 34.fxe5?? (Losing, after 34.Nh4 exf4 35.exf4 Qd4 36.Qd2 Qf6 Black is doing well with Nc6– d4 to follow) 34…Rg6 35.Nh4 Rxg3 36.d4 (36.Nxf5 is today’s first puzzle) 36…Qg5 37.Ng2 cxd4 38.exd4 Nxd4 0–1

Black to play and win

A bit of fun from the ECF’s 24-hour charity Blitz marathon ‘Checkmate Covid The Rematch’. The insertion of a2-a3 and a7-a5 enables Black to trap the white queen on e7, as the b4 square is unavailable. However, White, GM Gawain Jones, had seen further.
