It is literally the best end-game book ever written and the majority of those who read it are masters, which is a book that chess players who have reached a certain level should read and study the matches again and again. It is a book that guided me on my chess journey. It is one of the 3 best chess books I have read so far rather than the end of the game. I strongly recommend the 2nd, 4th and 6th edition. Too much G.o.a.t.
