The Philidor Defense for Black – every line at a glance – Learning studio

Every row is a line of the course, every column a move with White's and Black's move. A row shows only what differs from the row above – empty cells are the same moves as above. ? marks a mistake of the opponent, ↪ a transposition with the number of the line it leads into (a click jumps to it), ↺ a position the same line had before; on the right Stockfish's evaluation at the end of the line. A table per variation, before it every move up to there. A click on the number at the start of a row opens the line in the course.
