Zugzwang analyzes your chess games over time to find repeated mistakes and decision patterns that you may not notice from reviewing single games. Instead of generic puzzles or engine-only explanations, it focuses on how you actually play across multiple games and identifies the situations where you consistently lose advantage. It then turns those patterns into targeted training positions and drills so you can practice the exact types of positions you struggle with. The goal is to help players improve faster by focusing on real weaknesses rather than isolated game analysis.
