Guess the missing move from Samsung semifinal

[oren]

igokisen and TOM both are missing a move.



Between moves 55 and 56 is a missing white move. What do you think it is?

TOM falls over in a rather amusing way as it continues to alternate with the wrong colors.

It's funny, it seems to happen fairly often and I can't work out how.

For what it's worth, Oren, I'm not guessing because I've already seen the error-free game record .

It's not P12 is it? I'm not sure I'd understand the point of the move if it is, but that's what the shape looks like to me.

Looks like n13 to me. Explains the sequence around o15, and makes o12 a pretty basic move.

One of my (self-imposed) jobs is to get the printed records of a lot of Chinese and Korean games, like weiqi league games, and I check the printed record against the internet copy. There are a surprising number where it appears that the recorder has missed moves, probably because a sequence has been played fairly quickly. Some games also show either a "ghost" move, with an incorrect result, or fewer moves than in the book, again with the wrong result. The publishers then correct the record and publish a "clean" version. Unfortunately, we cannot know which games will be affected until the book comes out.

Best wishes.

My guess was P12 too but the 6d at club said n13. It was interesting to try to figure out what makes the most sense.

[hyperpape]

By the time you get to , it does seem obvious that it was n12. At least in hindsight.

I think that this might be the correct version.



Best wishes.
