Know the Terrain Vol. 5: The Philidor Structure

The information explosion has led to a massive increase in opening theory. But how often do you win a game with a prepared line? What gives strong players the edge over their opponents is not some blockbuster novelty, but a deep understanding of the pawn structures to which their openings lead – an understanding that lasts into the middlegame and endgame, and is transferable between different openings with similar structures. In this DVD, Sam Collins looks at the Philidor Structure (white pawns on d4 and e4 against black pawns on d6 and e5, excluding the King’s Indian/Old Indian positions which arise after White plays his pawn to c4). While formed on the 2nd move in the Philidor, the structure is characteristic of many Open Games, including the Italian Game and, of course, the Closed Ruy Lopez. Perhaps because of the structure’s flexibility (resulting in completely different types of positions depending on whether White takes on e5, Black takes on d4, or the central tension is maintained) little effort has previously been made to define the plans for both sides. The structure is one which arises in a sizable minority of games in all elite tournaments, a fact reflected in the selection of games, featuring impressive efforts by the world’s best players including Carlsen and Caruana who owe some of their most important recent successes to stunning wins in this structure.
