Conceptual Rook Endgames (Hardcover)
Rook endgames are the most frequently recurring endgames and also one of the most exciting areas of chess, with mind bending tactical opportunities and dizzying nuances available. They have unsurprisingly been a big topic in endgame literature, with a heavy focus on the set theoretical positions and their logic and fixed conclusions (see the excellent Theoretical Rook Endgames by GM Sam Shankland, published as a sister volume to this book as the peak example of this).
Grandmaster Jacob Aagaard is the most talented chess writer of his generation. He won the British Championship in 2007, but is mostly known for his multi-award winning books and his work with students that have won club, country, state, national, continental and world championships, as well as Olympiad golds (board and overall), the World Cup and Candidates tournament.
