This is a collection of 500 chess puzzles from games by the best titled players. The puzzles were compiled from thousands of games played in the second half of 2019. Each puzzle represents the critical position of the game and each unique solution has been checked by a grandmaster rated chess engine. For the students wanting to see two or more moves ahead, chapters are grouped by mate in 2, mate in 3, and mate in 4+. The "Move and Win" chapter is reserved for even positions that result in at least a two pawn advantage for the winning side. Solutions with alternate variations are provided at the end of the book for all puzzles. An index of players is included.
