翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Zepler doubling ： ウィキペディア英語版 Zepler doubling Zepler doubling is a manoeuvre in chess in which a piece moves along a certain line (rank, file or diagonal), then another friendly piece moves onto that same line, then the first piece moves again in the same direction as before. The term is effectively limited to the field of chess problems. The first problem to show the idea (shown to the right), by Erich Zepler himself, is a simple and clear demonstration of the manoeuvre. The straightforward doubling 1.Rgb2, threatening 2.Rb8#, fails to 1...Bxd6, so the more roundabout Zepler doubling is required: 1.Rb4 Bg7 (now 1...Bxd6 is no good because of 2.Rg8+) 2.Rgb2 any 3.Rb8#. Zepler doubling can be contrasted with another doubling manoeuvre, Turton doubling. ==References== * David Hooper and Kenneth Whyld, "Erich Ernest Zepler" in ''The Oxford Companion to Chess'' (Oxford University Press, 1996) 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「Zepler doubling」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
