his death, one of Greco's now-lost manuscripts was adapted as The Royall Game of Chesse-Play by Francis Beale in London. Beale's book—and others like it—helped Greco's work reach a much larger audience than had his predecessors'. In particular, Le Jeu Des Eschets, published in Paris 1669 became the principal source for the later English editions by William Lewis (1819) and Louis Hoffmann (1900). Games (as published by Beale) were not described in notation; rather, the movement of each piece was described in English, for example: The Fooles Mate. Black Kings Bishops pawne one house. White Kings pawne one house. Black kings knights pawne two houses White Queen gives Mate at the contrary kings Rookes fourth house. in which "house" refers to a square on the chessboard. In addition to the games ("Gambetts") listed in his manuals, Greco often gave general advice to his readers and an overview of the rules of chess ("The Lawes of Chesse"). These ranged from the familiar ("If you touch your man you must play it, and if you set it downe any where you must let it stand") to the obsolete ("If at first you misplace your men, and play two or three draughts, it lieth in your adversaries choice whether you shall play out the game or begin it again."). Greco also describes the necessity of announcing check to one's opponent (still common in informal play but not in competition) and the disgrace of what he calls a "blind Mate" – a checkmate given but not noticed. The "Lawes of Chesse" were also not entirely standardized in Greco's time; for that reason, the rules as published by Beale would have been meant for a specific population. For example, Greco specifies that when castling in France, "the Rook... goeth into the Kings house". In other countries the rules for castling were different. Modern castling, which Greco also describes, is sometimes called "alla Calabrese" in Greco's honour. Openings named for Greco Greco Defence: 1.e4 e5 2.Nf3 Qf6 – A popular opening choice by novice players, it has also been used by players who, according to International Master Gary Lane, "should know better". Also known as the McConnell Defense. Greco Countergambit: 1.e4 e5 2.Nf3 f5 – An aggressive but rather dubious choice for Black which often leads to wild and tricky positions. FIDE Master Dennis Monokroussos even goes so far as to describe it as "possibly the
