Section 1: Basic 1-Move Checkmate

・ Tsumeshogi are shogi puzzles aimed at 'checkmating the king'. They are the best practice method for training the most important endgame skills in actual play, and a learning method that all shogi enthusiasts should tackle.

・ By continuing tsumeshogi, you develop accurate reading ability in the endgame, concentration to not miss checkmate opportunities, and judgment in complex positions. Professional players also solve tsumeshogi daily.

・ 1-move checkmate is the introductory level of tsumeshogi, but mastering this will dramatically improve your win rate in actual games. Even though it seems simple, practice is needed to solve them accurately and quickly.

・ Once you can reliably solve 1-move checkmates, you'll stop missing checkmate opportunities in actual games and be able to escape accurately when your opponent threatens checkmate.

・ Head gold is the most basic and important 1-move checkmate pattern where you place a gold general (or a piece with the same movement) directly above the opponent's king to achieve checkmate.

・ The king can move in 8 directions, but when head gold is applied, the top, upper-left, and upper-right directions are blocked, and with escape routes sealed by the board edge or other pieces, checkmate is achieved.

・ Conditions for head gold to succeed: The king must be near the board edge or surrounded by other pieces, and you must be able to place a gold general directly above it.

・ Head gold variations: Promoted pawn (tokin), promoted lance, promoted knight, and promoted silver can achieve similar checkmates. Remember you can substitute with these pieces when you don't have a gold general in hand.

・ In actual games, create head gold opportunities by driving the opponent's king to the edge or surrounding it with pieces. Always be conscious of the opponent's king position and surrounding situation.

・ A common beginner mistake is thinking it's head gold when the king has escape routes. Always confirm all escape routes are blocked before making the move.

・ Horizontal rook checkmate: When the king is at the board edge, you can achieve checkmate by placing a rook horizontally. This is effective when the king cannot retreat and the front and back are also blocked.

・ Vertical rook checkmate: A checkmate method attacking with a rook from the front or back of the king. It's especially powerful when the king is at the edge and cannot move sideways.

・ Conditions for dropping rook checkmate: The king's escape routes must be limited by other pieces or board edges, and you must be able to drop the rook in a position where it can reach the king.

・ Promoted rook (dragon king) checkmate: Dragon kings can move diagonally in addition to rook movements, allowing for more complex checkmate patterns.

・ Coordination with other pieces: Even when a rook alone cannot achieve checkmate, combining it with other pieces can create powerful checkmates. Coordination with gold and silver generals is particularly effective.

・ Diagonal bishop checkmate: Bishops utilize their long diagonal range to checkmate the king from far away. This is especially powerful when the king enters the bishop's diagonal line.

・ Bishop drop checkmate: By dropping a bishop piece in hand at the appropriate position, you can achieve checkmate in one move. This utilizes the bishop's long range.

・ Promoted bishop (dragon horse) checkmate: Dragon horses can move one square vertically and horizontally in addition to bishop movements, creating more complex and powerful checkmates.

・ Using opponent's pieces: There's also a technique of using opponent's pieces as shields to direct the bishop's range. In this case, the opponent's pieces also serve to block escape routes.

・ Bishop and other piece coordination: Even when a bishop alone cannot achieve checkmate, combining it with gold generals or rooks can create beautiful checkmates.
