As a result of the London Candidates tournament, Magnus Carlsen will challenge Viswanathan Anand for the World Championship in Chennai in November, with a match budget exceeding $5 million. Between now and then I shall give occasional extracts from heroic deeds from past world title clashes. This week’s game comes from the marathon series of battles between Garry Kasparov and Anatoly Karpov. The puzzle is a coruscating victory by Alexander Alekhine, who held the world title from 1927 until 1946, when he died as champion, with a break of two years between 1935 and 1937.

Bogolyubov challenged Alekhine twice but was crushed both times. He was not an unworthy opponent, though, having won a match victory against Nimzowitsch, the simultaneous championship titles of the USSR and Germany, and two tournament triumphs ahead of Capablanca.

White strongly supports his central e4-pawn, and three black pieces – rook on e8, knight on f6 and bishop on b7 – are left without work. 19 ... Qd7 The queen will not be best placed at b5. The natural 19 ... d5 was better. 20 Nc4 Qb5 21 Rc3 The prelude to a rather harmonious arrangement of the pieces.

Bc8 22 Be3 Kh7 23 Qc1 c6 This weakening of the d6-pawn places Black on the verge of defeat.

Qd8 29 d5 Qxe8 30 d6 the avalanche of white pawns supported by the heavy pieces is bound to sweep away everything in its path. 29 Kh1 Qd8 30 Rd1 The co-ordination of the black pieces is completely destroyed, whereas White’s queen and both rooks are very strong. 30 ...
