Checkmate in 2- My first book

I have written and published a chess book for the first time in my life. It is a collection of 300 positions mostly from real games ( some of those are form the games I have played, but not too many,:)), few problems and some invented positions (those were made by me slightly altering the positions from some games, but there are not too many of those either). In all the positions there is a possible checkmate in 2 which cannot be defended. 

This is actually a workbook. I remember that I always improved my play by solving tactical puzzles, so I think that this collection can also help lower rated players, regardless of having less text.

By clicking look inside you can basically see what the book is about. It has 24 puzzles followed by soulutions, then the next 24 and so on.
