The miniature is not a game in which a player has blundered or either lost material or overlooked a mate, but one in which a slight error of judgment is immediately concretised.Few books have been published on the subject: Modern Chess Miniatures (Barden and Heidenfeld), The 1,000 Best Short Games of Chess (Cherniev), Miniature Games (Du Mont).
