Find the weak spot in your chess — before they do.
Most trainers feed you random puzzles and call it practice. Weakspot watches how you actually lose — the forks you walk into, the back-rank you forget, the move you always rush — and drills the gap until it closes. Start with the puzzle below. It's real, and it's waiting for your move.
This board is real. Make the move.
No video, no mockup. A genuine tactic, validated move-by-move. Find the idea and the board responds — miss it, and it shows you exactly where you went wrong. This is one puzzle. Weakspot has one for every weakness you have.
White to play and win.
There's a single move that turns the position. Click a white piece to see its legal moves, then play the one that lands the blow. Trust the pattern.
Three moves to a trainer that knows your blind spots.
It isn't another endless puzzle stream. It's a loop that gets sharper every time you play — built around the one thing generic apps ignore: you.
Import your real games
Connect Chess.com or Lichess, or paste a PGN. Weakspot replays your losses through an engine and finds the exact moments you let the win slip — the move before the move you regret.
It names your weakness
Not "you're 1450." Something useful: you miss back-rank mates, you hang pieces in time pressure, you never see the quiet move. Seventeen patterns, ranked by how much rating they're costing you.
You drill the gap, not the average
Every session targets your worst pattern first, then spaces it for memory. Close one weakness and the next surfaces. You don't grind 10,000 puzzles — you fix the 6 that lose you games.
See the leak before it sinks the game.
After a handful of games, Weakspot draws you a map most players never get: a ranked, honest read of where your tactics break — and a clear order to fix them in.
Tactical weakness map
player · youGeneric training treats every gap as equal. Yours aren't.
A 200-puzzle streak feels productive. But if 4 of every 5 losses trace back to the same blind spot, you're rehearsing what you're already good at and avoiding the thing that actually beats you.
Weakspot ranks the percentage of your losses each pattern explains, estimates the rating it's quietly costing you, and puts them in repair order. Close the top of the list and watch the whole map fall.

Median rating lift in 90 days
Across players who drilled their top weakness three times a week. Not magic — just practice aimed at the right target instead of a random one. Individual results vary with starting level and consistency.
Spaced for memory
Beat a pattern and it returns days later, just before you'd forget. The schedule is automatic — you just show up.
Five minutes, real
Sessions are short on purpose. Targeted reps beat marathon grinds that just tire your pattern recognition out.
Your games are private by default
Imports are analyzed for your eyes only. We never publish your losses, sell your data, or train public models on your play. The whole point is an honest mirror — so we treat it like one.
Every device
Drill on the train, review on the laptop. It syncs.
Explains the why
Every miss comes with the idea you didn't see — in words, not just arrows.

The players who stopped grinding randomly.
"I'd done 8,000 puzzles and plateaued. Weakspot told me 70% of my losses were one thing — quiet moves. Two weeks on that alone and I broke 1600 for the first time."
"It's almost rude how accurate the map is. 'You hang pieces under 30 seconds.' Yeah. I do. Saw it, drilled it, and my time-scrambles stopped being free losses."
"Other apps feel like a treadmill. This feels like a coach who watched my last ten games and circled the problem. Five minutes a day and the circles keep moving down the list."
Composite examples illustrating typical use. Rating gains depend on starting level, effort, and consistency.
