Shogi - Japanese chess
This is the first problem in a small book I have, check-mate in 1 move. The opponent's King is in the back right corner of the board. You have a Pawn on the third row in front of it. In your drop zone, you have a Rook, a Gold General and a Silver General available. Please use the spoiler tag to post your answer :) ::: spoiler Solution Drop Gold General in front of the King at 1二, protected by the Pawn at 1三. Wrong moves: - dropping the Rook at 1二, at 3一 or at 4一 lets the King escape to 2一, - dropping the Silver General at 1二 lets the King escape to 2二 - dropping a Gold or Silver General at 2二 lets the King take General back at 2二, since it isn't protected by the Pawn. ::: Reminder of the movements of the pieces: ![](https://lemm.ee/api/v3/image_proxy?url=https%3A%2F%2Fdiscuss.tchncs.de%2Fpictrs%2Fimage%2Ffd0b974d-212a-4878-8296-f6209e30de40.png)
