two space extension  

W2 in response to B1 is a slow but steady move. White may choose this joseki if the position on the top side merits such a low and solid position.

mistake  

It's a mistake for White to counter-atari with 8 -- White's shape get split.

Dieter: this is a doubtful comment. When analyzing this position with ZBaduk , this variation is considered very favorable for White. See next diagram.

Even  

Instead of a in previous diagram, B1 and B3 cut through with better shape. After W4 and W6 capture a stone, B7 keeps the two White stones in check.

Evaluation of the joseki  

Zbaduk thinks that W8 is a little submissive, compared to previous diagram. For Black, playing a after W8 is not urgent. White has already been forced into a low position and Black's stones may be considered forcing moves In the opening stage tenuki might be more valuable than reinforcing here.

This appeared in the 1977 Kisei match between Fujisawa Shuko (Black) and Hashimoto Utaro (White), both 9-dan professionals. W1 invades the high Chinese opening, and B2 invades the White upper left corner in a tit-for-tat response. Owing to the very strong Black influence in the lower left, W3 chooses the two-space extension over attacking B2 by the diagonal attachment at a or even the more conservative small knight's move at b.
