Checkmate in One or Two

I am in the process of creating a checkmate exercise book aimed at beginning players. It consists of 152 checkmates in one organized by the piece that delivers the final blow. Then, another 152 exercises are checkmate in two from the same games. All 304 exercises are repeated in a series of 17 sets, but no longer organized in the sequence found the first time through. This book should be available from Amazon in early January both as a print text and in Kindle format.

Below is half of one of the sets. White to move. Checkmate in one or two.
