From 1950 to 1962, the challenger for the world title was determined by a Candidates tournament of the world’s leading grandmasters, apart of course from the world champion. This was deemed an improvement on the previous system whereby the incumbent could accept or decline challenges as he saw fit, subject to pressures of finance and prestige. Thereafter Fidé, the world chess federation, adopted a number of experiments, some successful, some less so, such as the qualifier for the 2012 championship which was determined by quickplay games, an affront to classical chess.
 
Since last year, though, Fidé has sensibly reverted to the great tournament format of yesteryear, with splendid events in London and Khanty-Mansisk. These have delivered two worthy winners, Carlsen in 2013 and Anand this year.
 
This week I pay tribute to some of the great Candidates tournaments of the past.

However he is looking at the wrong side of the board. White is, in fact, well placed to start a queenside attack with 16 c5 to be followed by b4. 16 … Nxe5 17 Rxe5 Bf6 18 Rh5 This looks terrifying but White’s attack is illusory. 18 … g6 19 Rch3 (see diagram 2) If now 19 … gxh5 20 Qxh5 Re8 21 a4 Qd6 22 Qh6 Bg7 23 Qxh7+ (23 Rg3 looks murderous but 23 … Qxg3 destroys White’s attack) 23 … Kf8 24 Rg3 Bf6 25 Qh6+ Ke7 26 c5 and White wins.
