An instructional book about the crucial questions that masters ask themselves before making a move. Beginners learn to ask themselves beginner's questions. As they improve, they ask more sophisticaed questions: 'What did my opponent's last move allow me to do?, 'Where is his position weakest?, 'Should I take an irrevocable step now or wait?'. For chess master players these are almost subconscious checklist questions. A key to improving is to ask all these questions and find the right answers. This book is aimed at players who are well past being beginners but far from becoming masters
