The checkmate of the opposing king is the ultimate goal that both players aim for in a game of chess. To approach this endpoint of the game, it is essential to know checkmating patterns and to recall them when necessary, provided they are still hidden within the position. Only by recognizing a potential checkmating pattern can one cast a checkmating net or execute a checkmating combination. However, it is also crucial for defense to timely perceive the checkmating threats from the opponent that are already emerging in the distance. Kurt Richter and Rudolf Teschner have taken on the task of sharpening the reader's awareness of checkmating patterns to train checkmating combinations on this basis. The checkmating patterns and combinations, which can be found in enormous variety and in all phases of the game, embody this concept.
