Version 0.7 · 16 October 2026
- Load a saved game: import one PGN from a file or pasted text, then continue as White or Black. The moves are checked before the active game is replaced.
- Clearer scores: the thinking panel shows the change in positional value as well as its total.
- Closer to the hand calculation: square roots use one-decimal rounding. An impossible capture of the opponent’s king is excluded when calculating hypothetical mobility.
- Worked history: compare e3 and e4 component by component, and see five opening-score comparisons in the fidelity notes.
- Mobile play: the players and move record remain visible beneath the board. A short guide explains castling, en passant, promotion and saved games.
- Recovery and records: saved PGNs include the result of completed games, and a failed calculation leaves the controls available to retry or undo.
Changing the rounding convention can change the engine’s choices. The search remains bounded and the reconstruction does not claim to reproduce every move of Turing’s manual game.
