Summary of Statistics for this Game Tree

Number of lines: 638
Number of positions: 3494
Longest line (halfmoves): 63
Greatest depth: 8

The length of a line is the number of halfmoves from and including White’s first move to the last move of the line.

“Depth” of a line is the number of deviations from mainline continuations required to arrive at the line’s terminal position.
