You can also seek out Arpad Foldeak's book on Chess Olympiads, which has the crosstable of the final. The 54 Paris entrants were arranged into nine preliminary and final sections. Only the section winners qualified. Matisons' win with Black against Hromadka is the game usually quoted in this context, so I will publish a different one. Matisons was hard on the tail-enders and the following was his last round game.
White breaks open the centre with advantage.
To prevent Qh7, but now the pressure is intensified in the centre. In the field of endgame composition, Matisons' understanding of chess reached its highest level. Take a look at the diagram on the book cover. I'll talk you through it. The bishop prevents Re5, so it is not hard to see that White's first move must be 1 Kd2.
