BQM 88 / Background

Sub-page of BQM88

The information below is taken from the booklet 只此一手 no. 5, problems 1 and 2.

Joseki deviation.  

The sequence follows 3-4 point low approach two-space high pincer two space jump, but W6 and W8 deviates from the joseki.

Correct response.  

The correct response is to atari with B1 and then block on the inside with B3. The proper move for White is to defend with W6, but after Black connects with B7, Black's position is described as "thick". Black can then aim at gaining profit with either a or b.


Instead of defending at a, the sequence from W1 to W7 is described as overly greedy. B8 is a tesuji, a strong counter-attack.


If W1 attach, then B2, B4 is said to be the way to break out. After B6, if White a, then Black b finishes the job. I think I have a beginner exercise that has this problem somewhere?


White can capture the corner with another two crawls along the second line to increase liberties, and then play at W5. But in the end, White will still need to fill up the liberties, so the gain by capturing the corner is "not big".


The position in BQM88 arises when White plays W3 in place of a. White playing at a is shown in the diagram labelled Attach above.
