Hmm. There is a lot you can do to customize analysis. You can pick which move quality types to highlight. I think you could only show blunders.
And you can play games against the computer from any point in any pgn.
And there is a lot you can do to customize bot play. But I don't think you can set one set of parameters for the first ten moves and another for later moves.
/ I couldn't figure out what "imagines" are.
I want to customize chess to my liking. I like to play vs computer! Can I somehow let analyze show only blunders and don't show mistakes or inaccuracies, after end of game: I can go back and start playing from there... Also evaluation doesn't work all of the sudden, it doesn't show numbers like +0.84 anymore! I Am playing vs 2600 now, but i have checked both analysis and evaluation, it should work!
I think it would be also great, if you could enable inaccuracies and mistakes only first x moves just to get the game going. I have beaten 2500 after first 10 games without analysis and like with 4 takebacks from not paying attention, but I wouldn't have chance to beat it consistently! It is more fun like this just to get the game going, but I don't want being shown what to do every move, that's boring...
I don't want to show also best moves, but I got rid of that easily... It would be just easier, if this could be set!
NOTE: I have disabled imagines in my browsers, but i enabled it on chess.com, everything else works, not sure if this couldn't but it out somehow! All other permissions are unchanged, it worked before!
I Am using Chrome (stable) on Windows 10.
