I am a huge fan of the AI review that were recently introduced. So much so, that the AI review is one of the main reasons I support the site.
Having said that, I frequently have a strange feeling of missing out something important, when I look at the AI review charts. I play a lot of handicap games, and the chart frequently looks like this:
Or, like this:
The charts suggest that both games were boring. In the first, white had no chance, and in the second, black must have made a huge blunder. But the reality is, that both games were close and exciting. In handicap games the win rate swings from 0 to 100% very fast - hence the flat charts.
I was thinking on an alternative representation of chances. Instead of displaying win rates, OGS could display the score difference instead of win rate. kata-bot comments this information in Malkovich:
Winrate 0.01% ScoreLead -72.3 ScoreStdev 24.1
Using score lead and score deviation information an exciting new type of chart could be show. Something like this:
(The black line shows the expected score, the gray area shows the uncertainty of the score estimation.)
On a related note: it would be great to show the score value of individual moves in the AI review, instead of change in win rate.
