Surfaces where you spend disproportionate time in the opening phase (plies 1–16). Recurring leaks = the SAME position (FEN-keyed) you've faced 3+ times that consistently took long. Top long thinks = single moments that ate your clock. in book means the position was still in the named opening per lichess. The position diagram is the actual board you saw, and every game in that row reached this exact spot.
