Bjorn explains the blunder, not just the score.
Every explanation is checked against the board before he says it: what the move gave up, the line that punishes it, and the move that was there instead.
Move 28. White played Qxe5?? from a winning attack.
Coach Bjorn
why your move was a mistake
You had a winning attack, but taking on e5 with your queen throws it away. Black recaptures with the queen, you take back with your rook, and the queens come off the board. Even though you win a pawn in the trade, your most dangerous piece is gone. An 83% winning position drops to a roughly level endgame where Black's rooks spring to life. When you are attacking a king, keep your queen on. Trading it off, even for a pawn, lets your opponent escape.
✓
What the move gave up: material, the attack, the tempo.
✓
The line that punishes it, move by move.
✓
The move that was there, and how many players at your level find it.
Free gets five of these a day. Premium gets up to a hundred, on puzzles and on full game reviews.
Why upgrade to Premium?
The difference is not the numbers. It is whether the training keeps up with how much you play.
Every mistake, drilled
Free keeps ten drill slots. Premium keeps every blunder from every game, the moment you play it, and brings each one back until it sticks.
Bjorn on every move
Up to a hundred explanations a day, on puzzles and on full game reviews, with his voice on every move instead of the first moment only.
Thirty times further back
Every drill is cut from your games, so reading more of them fills every room: more endgames to hold, more trades to call, more blunders to build sets from. The Career Report reads your years of play, era against era.
Every pack, every set
All eighteen theme packs, twenty Woodpecker sets on sixty-five themes to mix freely, and unlimited hints and answer reveals.
Three accounts per platform
Your main, an alt, an old username. Chess.com and Lichess each, all scanned into one training plan.
Engine and the fast lane
Lichess engine analysis from any position, and a priority queue so your puzzles are generated first.
