Using a Chess Engine? Use DecodeChess instead!

Chess engines are great, but they are not an effective learning tool for aspiring chess players as they do not provide a framework to understand to understand WHY the recommended move is good and WHAT the position is all about. When you use an engine to analyze your games (or any game in general) you are still missing the key elements that can bridge between the engine’s cold mathematical calculations and our human understanding of chess.
