“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.
ONLY SPEND TIME ON THE MOVES YOU'LL ACTUALLY SEE
Most books and courses are written by masters for masters. Chessbook lets you avoid obscure grandmaster lines and focus your effort on the moves that are common at your level.
TARGETED PRACTICE MEANS YOU'LL NEVER FORGET A MOVE
Chessbook uses spaced repetition, a scientifically proven technique to memorize openings quickly and thoroughly.
COLLECT ALL YOUR OPENINGS IN ONE PLACE
Nobody gets their whole repertoire from a single course or book. Chessbook lets you combine openings from multiple sources to create a custom repertoire just for you.
REVIEW YOUR ONLINE GAMES FOR OPENING MISTAKES
Get instant feedback on how well you're sticking to your repertoire. Chessbook supports both Lichess and Chess.com
LEARN MIDDLEGAME PLANS FOR ANY OPENING
See how top players handle the positions that result from the openings you play.
