Only One Move Wins: 360 Chess Positions With a Single Proven Answer, and Why Every Other Falls Short

Not the best move. The only move. Every position in this book has exactly one move that forces mate. Not a move an engine prefers by a little, and not the move an author liked best. One move that works, and a page that shows you why the others fall short. That claim was checked by exhaustion. A chess engine searches: it looks as far ahead as the clock allows and reports the best line it found. For this book a program did something different. It walked the complete tree of legal moves out to the end of the mating sequence, kept every branch, and counted how many first moves force mate inside the stated limit. A position earned its place here only when that count came back at one. The same walk wrote the solutions, so every defense Black owns is answered in print, and under each answer you will find the tempting tries listed one by one with the resource that breaks them. The check that looks like the end of the game. The capture that looks free. The move your hand was already reaching for. Those near misses are the part of the page that teaches. What is inside - Mating shapes you meet in real games - back rank, Anastasia's, the supported queen, and the rest, each chapter opening with one position worked through to mate before you are asked to find any. - Positions grouped by the idea that solves them - the quiet move, the sacrifice, the fork, the capture that removes a defender. In this part the chapter title stops telling you what you are looking for. - Mates in three, for the point where holding one branch in your head stops being enough. - King and pawn endings, where every position carries a proven result rather than an evaluation, because that ending has been solved completely and the exceptions could be counted instead of mentioned. Built for paper Large diagrams, two to a page, on 8.5 x 11 inch pages, printed dark for reading rather than sized for a screen. A difficulty rating from 1 to 4 sits beside every position, computed from counts taken off the board itself: how many checks and captures fail, whether the key move is quiet, how wide Black's choice of defense runs. Written for the club player rated roughly 800 to 1500 who wins games and loses games and keeps walking past mates that sat in plain view. No app. No website. No video course. No pages to fill in.
