CHESS

The first truly modern player was the great Frenchman Frangoise Andre Dani- can Philidor (7 Sept 1726 – 25 Aug 1795). Both over the board and in the realm of ideas Philidor dominated his contempor- aries. Dr Max Euwe wrote of Philidor: 'By illustrating his principles in his book L'Analyse des Echecs, Philidor laid the first stone in the edifice of modern chess.'

Philidor's revolutionary insight into chess strategy was his appreciation of the function of the pawns. In the games of Philidor's predecessors the pawns were mere cannon fodder or obstructions hampering the free play of the pieces. Philidor understood, on the contrary, that the pawns were the very backbone of the game. In his games he always tried to build a great wall of pawns in the centre and his victories frequently came because his be- wildered opponents could not understand the nature of his strategy. It has even been suggested that Philidor's revolutionary theories concerning the pawns, the peasan- try of the chessboard, were a remarkable reflection of the revolutionary political events in the France of his day.

Philidor's Defence, 1 e4 e5 2 Nf3 d6, has been virtually neglected since his day, though it was briefly espoused by Murphy, Nimzowitsch and Alekhine. Now, a new book, Winning with the Philidor (£10.99, B. T. Batsford), by the English grand- master Tony Kosten reveals the Philidor in its full glory as a perfectly viable and coherent defensive system against 1 e4. Black even has a choice of defensive

methods, fianchettoing his king's bishop, dourly defending the centre, or even the Philidor Counter-Gambit (1 e4 e5 2 Nf3 d6 3 d4 f5), which is by no means as dead as theory would have us believe. The most fascinating system is that with . . . g6, and I give three games cited by Kosten to de- monstrate its potential.
