You get immediate feedback, can reveal answers when needed, and can review your results as you improve. Version 3.0.1 expands ChessNotation into a broader board-vision trainer. Home is now organized into four focused families: Notation Training, Timed Training, Board Skills, and Position Recall. Board Skills groups Square Recognition and Piece Movement drills, while Position Recall adds reconstruction practice after a timed study phase.
