Go Blindness
   

The inability to see the truly obvious, as in What! Oh! Those stones are/were in atari?. Examples include:

  • Losing a group of cutting stones and allowing a group of the other players stones to live.
  • Playing ko and forgetting to play the ko once your opponent has responded to a ko threat.
  • Filling your own eye in an attempt to convert a group alive in seki to an unconditionally alive group.

Go Blindness usually strikes near the end of the middle game or into the endgame. Amateurs are not the only ones to suffer from this malady. If memory serves, Rin Kaiho lost a title match game, if not the title itself, due to bout of go blindness.

Go Blindness is not a case of shortage of liberties or failure to read accurately or deeply enough, rather the absolute obviousness of the situation hides the significance of the position from the player, as if the unconscious preceives the situation, desparately tries to alert the conscious mind, which is too busy with some deep reading or careful consideration of a different matter bothered to listen to so blatantly obvious a statement!


The blindness to atari can be cured by training to see what is an atari. Probably with some exercises one can see an atari by intuition. Head over to spot the atari.

Niklaus: I think the problem occurs only when the move has another meaning besides the atari, for example taking away a point in yose or something like that. You think your opponent has played a one or two point gote play, which makes you think it is the right time to play the fancy complicated sequence you just figured out. Stuff like that sometimes happens to me in fast games once in a while.

Alex Weldon: Certainly, as one gets better, one misses these things less often... it's been a while since I've missed seeing an atari. It's not just a matter of being able to recognise an atari, though. I would still occasionally not see an atari or auto-atari myself when I was around 10k, and a 10k certainly understands what atari is. I think the reason I don't do it anymore is that I'm in the habit of keeping track of the numbers of liberties my groups have... so if someone plays adjacent to a group I knew was at two liberties, it's unlikely that I'll fail to notice that it's in atari.
