Chess Treasury of the Air (edited by Terence Tiller; Penguin, 6s.) is an anthology taken from Network Three broad:Ws in the years I958-r964, which I :can warmly recommend to players of all sexes, ages, tastes

and strength. One of the best sections is 'Favourite Games and Gravest Errors', and here is Euwe's favourite game, taken from this.
