ChessMem: Chess Openings

Learn chess openings and traps in a way that sticks: spaced-repetition practice. AI explanations break down why the masters played each move.

Master Chess Openings Through Memorisation ChessMem turns opening study into something you actually finish. Instead of watching videos and forgetting everything by your next game, you practise master-verified lines through active recall — and the app brings them back at the right moment so they stick for good. HOW IT WORKS Pick an opening. Drag pieces to play the correct moves. Wrong moves show you the right answer. Score 100% on a variation and it enters Mem Mode, where spaced repetition reviews bring it back at increasing intervals — first after a day, then three, then a week, two weeks, and on from there. By the time you sit down to play, the moves are automatic. OPENING TRAPS 31 tactical traps built in — the sharp, surprising lines that win games when your opponent walks into them. Learn the traps in your favourite openings, recognise them when opponents try them on you, and add a few sneaky weapons to your own repertoire. A REAL REPERTOIRE, NOT JUST THEORY • 162 curated openings, 7,700+ positions • Up to 15 moves deep on every line • Every move verified against the Lichess Masters Database • Three depth levels: Basic for the core lines, Medium for common deviations, Full for serious repertoire builders COLLECTIONS BUILT AROUND YOUR STYLE Choose a learning path that matches how you like to play: • Solid — sturdy, positional openings • Aggressive — sharp, attacking weapons • Classical — time-tested main lines • Creative — surprise weapons and offbeat choices • Foundational 1, 2, 3 — a progressive path from beginner to club player Each collection covers one opening for White plus responses to both 1.e4 and 1.d4 as Black, so you finish with a complete repertoire. AI EXPLANATIONS Stuck on why a move is the move? Tap any position for a plain-English explanation of the idea behind it — the threat, the plan, the alternative your opponent has to worry about.
