The Saavedra position is one of the best known chess endgame studies. It is named after the Spanish priest Rev. Fernando Saavedra (1849–1922), who, while living in Glasgow in the late 19th century, spotted a win in a position previously thought to have been a draw. The solution is a famous example of a necessary underpromotion (a promotion of a pawn to a piece other than a queen). ==Solution== The position as it is usually given today, with White to move and win, is shown in the diagram to the right. The solution is: :1. c7 Rd6+ :2. Kb5 (2. Kc5? Rd1 and 3...Rc1! If 2. Kb7? Rd7 pins the pawn) :2...Rd5+ :3. Kb4 Rd4+ :4. Kb3 Rd3+ :5. Kc2! Rd4! :6. c8=R! (threatening 7.Ra8+; instead 6.c8Q? Rc4+! 7.Qxc4 is stalemate) :6...Ra4 :7.Kb3 Black must either lose the rook (allowing White to easily checkmate) or be checkmated by 8. Rc1 . This is one of the most famous examples of underpromotion in chess and a rare example of a player being famous for a single move . 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「Saavedra position」の詳細全文を読む スポンサード リンク
