Hi steelsmitty,
The ai-review feature is very helpful imo. For the same reasons as runarberg listed in his post, and also to learn ai openings.
If you want to review your games there are other ressources too.
•If you got a pc you might consider installing lizzie or katago.
•There are at least two sites, zbaduk and ai-sensei, on which you can upload and analyze your games by ai. Both are limited in functionalities up until you subscribe but can be useful.
The only negative point with the ogs ai-review is that some people can’t save the variations in a sgf-file after analyzing a game which is played on another platform. There is a subthread on this issue here: SGF file download with AI review
Besides learning with the ogs ai, by subscribing you also support the site, which is a wholesome bonus. ^^
