Spaced repetition chess
Spaced repetition for chess openings
Remembering an opening is a timing problem as much as a knowledge problem. Blundr helps you revisit opening positions over time, with extra attention on the ones that still need work.
Recall beats rereading
Try to find the move before seeing the answer. Retrieval reveals what you can use in a game and what only felt familiar while reading.
Review the weak points
A missed position should influence what you practice next. Concentrate repetitions where they can improve your actual repertoire.
Keep positions connected
Opening families and branches provide context, so a review card is part of a playable plan rather than an isolated flashcard.
Make progress sustainable
Short, regular practice keeps opening knowledge available without turning chess study into an endless memorization obligation.
Turn understanding into recall
Blundr brings the positions you miss back into practice so you can build an opening repertoire that survives real games.
