Analyses
5 automatic angles of analysis across the entire tournament.
Approaching move 40
Time left on the clock just before playing the 40th move. Less time = more pressure at the time control.
Preparation depth (out of book)
First move where the player thought > 30s. The higher, the more moves their preparation covers.

Average time per move (moves 1-15) by ECO family of the game opening. Intensity = proportional to time. Hover a cell to see the number of games.
Does thinking longer help?
The cost of a move is the eval lost by the player (positive = bad move). We aggregate by think duration to see if thinking more produces cleaner moves — and who benefits most.
1530 moves analyzed
Median cost by think duration
Positive = the move dropped the eval (bad move). Close to 0 = neutral move. The blunder rate is the % of moves in the bucket with a cost > 150 cp.
Who does time help? (median < 1min vs > 5min)
Difference between median quality when the player thinks fast (≤ 60s) and when they think long (> 5min). Negative = their long thinks pay off. Positive = they would have done better to move faster.
