The half-open file can provide a line of attack for a player's rook or queen. A half-open file is exploited by the player with no pawns on it. Many openings, such as the Sicilian Defense, aim to complicate the position. In the main line Sicilian, 1.e4 c5 2.Nf3 d6 (or 2...e6, or 2...Nc6) 3.d4 cxd4 4.Nxd4, White obtains a half-open d-file, but Black can pressure White along the half-open c-file. The demolition of the pawn structure is a common theme in positions with half-open files, since doubled pawns or isolated pawns may create half-open files. ==Example== The game Loek van Wely–Judit Polgár, Hoogeveen, 1997〔(Loek Van Wely vs Judit Polgar, It (cat.16) 1997 )〕 demonstrates the power of half-open files in attacks. Despite having one fewer pawn than White, Black's possession of two powerful half-open files (her rook on the f-file and queen on the g-file) gives her a winning advantage. Black played 30...Rxf2+! and White resigned, anticipating 31.Rxf2 Qxg3+ 32.Kf1 Qxf2#. 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「Half-open file」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.
