A basic shogi mate training book with 100 useful problems. For each diagram, you will be given three different pieces in hand and you must figure out whether or not you can mate the king with each one of them. In some problems, all three pieces have a mate, while in other problems there may be only one piece that can mate. Therefore, in a way, you will be trying to solve 300 problems in total. The problems are composed by professional shogi player Daisuke Katagami. It is a compilation of three Japanese booklets from NEKOMADO.
