Help understanding the computer analysis output

Update February 17, 2020

The documentation for the AI review feature is available at https://github.com/online-go/online-go.com/wiki/Understanding-the-AI-review


Hi @Cyanriddle. Welcome on OGS.

The computer analysis feature is really new and still might change in appearance or other minor ways in the coming weeks. Therefore, the feature hasn’t got in the documentation.
Additionally, the documentation you found is an old one. You can find a much more up to date one at https://github.com/online-go/online-go.com/wiki


The graph shows the win probability for black and how it changed while the game progressed.
If it is at the upper bound, black is likely to win, if it’s on the lower bound, white is likely to win.

The bar above shows the probability to win for black and white for the current board position. If you explore a variation, the probabilities won’t change and still show the numbers for the root board possition.

The 10+% moves indicate how many moves of each player reduced their chance to win by at least 10 percent points.

The numbers on the board are the change of the probability to win for the player to play the next move. If the number on one move is -8.0 for example and black to play, that move would lower blacks probability to win from 74.6% to 66.6% for example. If it would be whites turn, whites probability to win would change from 25.4% to 17.4%.
The blue move is the move the AI would play. The actual played move is represented by a small triangle and a transparent white circle. The triangle is on the AI move when AI and player agreed on the move to play.

The green background now represents the time LZ spent on the variation. Brighter green means more time spent on variations of the move.
