The Wayward Queen Attack, also known as the Kentucky Opening,〔(Kentucky Opening ), Dubuque Chess Journal, May 1875, page 250 scanned at Hathitrust (original from New York Public Library)〕 Danvers Opening,〔''Edward Winter'', (Danvers Opening ) at chesshistory.com〕 Queen's Attack,〔Bronstein, David, (200 Open Games ), chapter 1, page 1, Batsford 1973〕 Queen's Excursion,〔 or Patzer Opening〔Lev Alburt & Al Lawrence,(''Chess for Everyone'' ), Rowman & Littlefield, 2010〕 is an unorthodox chess opening characterized by the moves: :1. e4 e5 :2. Qh5 ==History and nomenclature== 1.e4 e5 2.Qh5 has rarely been described in chess literature, and is very rarely played by strong players. Because of this, it has acquired several names over the years, none of which are universally used. The earliest known appearance in print was in the Dubuque Chess Journal in May 1875, where it was dubbed the ''Kentucky Opening'',〔 perhaps in reference to a game played in Danville, Kentucky which was published in the August issue of the same magazine.〔(Fields-Young, Danville Kentucky 1875 ), Dubuque Chess Journal, August 1875, page 371 scanned at Hathitrust〕 (This name was also applied by J. H. Blackburne to the unsound Jerome Gambit.) In the ''American Chess Bulletin'' in 1905, the opening was referred to as the ''Danvers Opening'', so named by E. E. Southard after the psychiatric institution where he worked.〔 Bernard Parham of Indianapolis is the first master-level player known to have advocated this line. Parham is known for his eccentric theories on the game of chess, which he has developed into what he calls the "Matrix System". Parham's Matrix System advocates early development of the queen in several positions, as in his favored line as White against the Sicilian Defence, 1.e4 c5 2.Qh5?! Parham argues that just as Richard Réti and Aron Nimzowitsch pioneered the hypermodern style of chess, his own ideas which are considered strange today may well be considered viable in the future. Several internet-based sources refer to 1.e4 e5 2.Qh5 as the "Parham Attack" or "Parham Opening". The most notable use of 1.e4 e5 2.Qh5 by a grandmaster occurred in 2005, when U.S. Champion and future World Championship contender Hikaru Nakamura played it in two tournament games. The best known of these was against Indian GM Krishnan Sasikiran at the May 2005 Sigeman Tournament in Copenhagen/Malmö, Denmark.〔(Nakamura-Sasikiran, 13th Sigeman & Co 2005 ). ChessGames.com. Retrieved on 2006-02-09.〕 Nakamura got a reasonable position out of the opening but lost the game due to a mistake made in the middlegame. He later wrote on the Internet, "I do believe that 2.Qh5 is a playable move, in fact I had a very good position in the game, and was close to winning if I had in fact played 23.e5."〔(Nakamura on 2.Qh5 ). Mig Greengard. Published 2005-05-05. Retrieved on 2009-02-06.〕 The previous month, Nakamura had played 2.Qh5 against GM Nikola Mitkov at the April 2005 HB Global Chess Challenge in Minneapolis. The game ended in a draw after 55 moves.〔(Nakamura-Mitkov, HB Global Chess Challenge 2005 ). ChessGames.com. Retrieved on 2006-02-09.〕 More often the opening is adopted by chess novices, as when actor Woody Harrelson played it against Garry Kasparov in a 1999 exhibition game in Prague.〔(Harrelson-Kasparov, Consultation game 1999 ). ChessGames.com. Retrieved on 2006-02-09.〕 Harrelson achieved a draw after being assisted by several grandmasters who were in Prague attending the match between Alexei Shirov and Judit Polgár.〔Hans Ree, (Jake, Joe and Garry ). ChessCafe.com. Retrieved on 2009-02-06.〕 The next year Kasparov again faced the opening as Black when tennis star Boris Becker played it against him in an exhibition game in New York.〔(Becker-Kasparov, New York exhibition 2000 ). ChessGames.com. Retrieved on 2006-02-09.〕 This time Kasparov won in 17 moves. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wayward Queen Attack」の詳細全文を読む スポンサード リンク
