"The Final Countdown advocates the use of key squares in calculation of king and pawn endgames rather than the "opposition" or "triangulation". I've always found king and pawn endgames to be incredibly difficult to calculate because, unlike other areas of chess, the whole purpose of calculation in king and pawn endgames is to lose a tempo and thus force the opposing king away from key squares so that the attacking king can invade. It's extremely difficult to calculate king and pawn endgames because tempos can be gained or lost by both sides in many different ways.
This book advocates the identification of key squares which the king either invades through or goes through in order to lose the appropriate tempo. The previous reviewer rightly pointed out the errors in the book (for example, in the section on blocked pawns, the authors state that if the invading king can occupy the 3 squares on either side of the opposing blocked pawn, the game is a win when obviously a draw results if the opposing king is in position to take your blocked pawn) but they are obvious and don't take away from the strength of the book, which is to calculate king and pawn endgames in a systematic way instead of counting endless "lose the tempo" variations."
