Key features: • Create a custom repertoire • Train with spaced repetition • Find gaps automatically • Avoid obscure moves • Handle transpositions • Find mistakes in your online games • Fast & modern interface “A fun and simple way to build an opening repertoire based on probabilities of most likely lines. You will actually learn the moves that will happen on the board!” —Grandmaster Eugene Perelshteyn FIND THE GAPS IN YOUR REPERTOIRE BEFORE YOUR OPPONENTS DO Chessbook calculates your coverage per opening so you always know what to work on. PICK THE BEST MOVES TO MAXIMIZE YOUR WIN-RATE Weigh up your options by looking at stats from master games, engine evaluation and results at your level.
