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.

1440 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.
