On Lichess, values was probably adjusted for the value for the average level of their games : 1700 level in 10 minutes games.
I'd want to have analysis for a higher levels : 2000 level in 2 hours.
I am now implementing a different approach to annotation. It is not based on the difference of the score, but is based on the impact of the error of the move.
Code: Select all
1. Blunder [??] - a move that would result to a decisive advantage to the opponent
2. Mistake [?] - a move that would result to a moderate advantage to the opponent.
3. Dubious [?!] - a move that would result to a slight advantage to the opponent.
Table:
Code: Select all
Decisive advantage [+- or -+] score >= +3.0 pawns
Moderate advantage [+/- or -/+] score >= +1.5 and score < +3.0
Slight advantage [+/= or =/+] score >= +0.25 and score < +1.5
Sample annotations with summary of number of blunder, mistakes and dubious moves for each side at the end of the game as comments.
