The Squeers method is probably the best for learning to play the middle game—`WINDER "winder", now go and clean it' and Euwe and Kramer's The Middle Game: Book I, Static Features (Bell, 35a.) adopts this practical type of approach. Middle game positions are classified according to certain theoretical aspects, but, as the authors say, 'ultimately it must be practice which dictates the classification', and the essential part of the instruction lies in the large number of illustrative games showing how the practical prob- lems are tackled by great players. The book can be

enjoyed just as a collection of games by lazy readers who don't wish to learn from it.

The following famous game is given as one of the examples of ptaY with rival pawn majorities.

White, ALEICHINE. Black, MARSHALL. Opening, QUEEN'S GAMBIT. (Baden-Baden, 1925)

Who am I to disagree?—but I would still slightly prefer to be White. la P—K R 3 Kt-1 3 3 13Q-4? of • • • From now on every move of
