BQM 221
This sequence is from Yang Yilun's The Fundamental Principles of Go, and it seems like a reasonable reduction since the marked stone is greatly weakened. However, when played against a large knight's enclosure...
He lists as the proper move. I can see that white has adequate resources after this.
However, this implies that white can get a better result if black plays in this way.
If white follows the same sequence, the circled stone is farther away, and ends up attacking white rather than getting weakened. How should white play then to take advantage of the squared stone?

Bill: If the ladder works, White can play -
, threatening
or
.
Dieter: I think the question is: can cut?
In this variation, White gets a forcing? sequence with ,
and
, before protecting at a (b?) and stabilize rather easily in the corner.
Bill: I kind of like . :-) Play might continue as in this diagram.
This variation looks more dangerous ... but for whom?
I think fails.
here also doesn't look very healthy.
The cut at miserably fails when
is one line closer as in this diagram.
Dieter: I'm going to reread now.
Shaydwyrm: Thanks for your insight! I can find no fault in your reading as yet, you have been very comprehensive.
This is, unfortunately, the move I had overlooked originally...
