Most players are probably aware of the 1930 game in which Kitani Minoru and Murashima Yoshikatsu were both deemed to have lost their Oteai game because they took a break for sleep instead of playing on. This is, however, not the only game in which both players have lost.

In 1990 Hane Yasumasa and Haruyama Isamu were similarly punished when White (Hane) played 242 at the point that should have been occupied by move 46 (J13). But 46 had by then
accidentally been shifted one point to the left (H13). As neither player had noticed, both were adjudged to have lost.

Strictly speaking, the game record here must be inaccurate because it does not convey the board position after stone 46 had been shifted - but no-one knows exactly when it was shifted!

I've never heard of this story, although it does remind me of tournaments that I've been to where both players stopped the clocks for a smoke break. Have you got any more to say about the Kitani game?

It is interesting that :w46:

is such a stretch. It is not part of any standard pattern. It makes one wonder whether that contributed to two professional players not noticing the accidental shift. Pattern recognition and good vs. bad shape training indeed!

Wouldn't the shift have to have taken place after Black's move 233? If the white stone were at H13 and J13 were empty doesn't move 233 look sort of strange in response to White 232? On the other hand, if the white stone were at J13 then Black 233 looks more reasonable as a response to White 232.

I wasn't aware of that either (nor that it was possible at all).
Why did they both lose ?

Would you have an sgf record to submit ?
thanks
