Analysis
Stats
The heatmap shows every square you've interacted with. Each square is colored on a gradient — pure blue means you've only ever correctly identified pieces there, pure red means you've only ever missed or misclicked there, and yellow sits in between. The redder a square is, the more consistently you struggle to spot hanging pieces on it.
Rating Trends
Attacker Blindspots
Shows which attacking piece types you tend to miss. A spike toward Pawn means you're often failing to spot pawns threatening your pieces.
Victim Blindspots
Shows which of your pieces you most often leave hanging. A spike toward Rook means your rooks are frequently undefended or under attack without you noticing.
Spatial Blindspots
Shows where on the board your attention breaks down. Rim = edge squares, Center = d4/d5/e4/e5, Enemy = opponent's half, Friendly = your own half.
