The Inner Game of Chess: How to Calculate and Win by Andrew Soltis

The Inner Game of Chess: How to Calculate and Win by Andrew Soltis is a practical instructional book focused on improving a player’s calculation skills, decision-making process, and competitive thinking during games.

The book explains how strong players evaluate positions by focusing on candidate moves, forcing variations, and the balance between tactics and strategy when calculating lines.

Soltis emphasizes the importance of thinking efficiently under time pressure, showing how players can avoid over-calculation while still finding the best moves through structured analysis.

It covers key practical themes such as when to calculate deeply, how to identify critical positions, and how to recognize which variations actually matter in real play.

Through examples from master games and instructive positions, the book demonstrates how calculation is guided by intuition, pattern recognition, and positional understanding.

A highly practical resource for club and tournament players aiming to improve calculation technique, game decision-making, and overall practical performance in competitive chess.
