So here’s a challenge: beat all 5 AI levels of cosumi blindfolded on 9x9 (there’re bigger boards but higher AI levels are disabled there). It’s definitely possible because cosumi is not very strong. Important point: if you play on top of a stone at any moment, you automatically lose.
Thankyou for posting this @S_Alexander. First attempt, fail.
Thanks to you I am back at the ‘recognising atari’ stage.
Will definitely try again. Maybe when I don’t have a headache.

Probably worth mentioning that the big green ‘Start’ buttons are for ads. Just click on the board size you want to begin.
One color go is relatively easy even for SDK (after a bit of practice). It may very well be that it’s easier on 19x19 because of joseki and more normal moves, while in 9x9 it’s all fighting and any move is valid. Plus, cosumi is pretty peaceful on 19x19. If you want to play on ogs, I’m up for a game.
Blindfold on the other hand is very hard. Here’s pros playing blindfolded (literally, heh) until move 100, with 1 chance to look at the board; if a player can’t continue, they can take blindfold off but receive penalty 5p/move until 100 moves:

I believe that it’d be superhuman to memorize the game without understanding it. Thanks to your knowledge yuou are able to replay bits of the game in your head knowing why certain things happened.
The deeper the understanding of reasons, the simpler is game recovery. It’s exactly the same as with replaying games from memory on 19x19. If your understanding is deep enough you are able to reason the game back to life.
