Just visualise the difference with a white move there:

They say that one should aim at playing moves that do more than one thing (as long as they are not half-hearted attempts at accomplishing those goals). Well, this move:
  • Makes black's corner 100% resilient for future attack, thereby solidifying black's moyo somewhat
  • Takes away white's eyespace in the corner, thereby threatening a splitting attack at 'a'
  • Takes about 10 points of territory
  • Robs white of the chance to make about 10 points of territory while threatening black's base
Enough?

Bill Spight's move is also interesting (he's quite a bit stronger than me). Still, I (humbly) think my move looks better than his :). It puts more pressure on white, and, as a bonus, it simply takes more points in the corner.


I guess it boils down to the comparison:

Two questions for both diagrams:
- Can black tenuki?
- How stable is white?

I don't think white's group is any weaker in the first diagram than in the second, especially when black wants to tenuki.
But in the first diagram, I'm not sure if I really want to tenuki...

Not that I would have found Bill's move on my own, but now that I have seen it, I like it ;)

They look perfectly ok to me. "a" I tend to avoid because it allows White to slide under, but it's a common way to develop outside influence, and seems like a good idea here - had you considered Q9 for the same thing? Outside influence is probably quite desirable for Black with respect to developing a big framework.


Also, if white slides under, black has either the cap at 'y' or the invasion at 'z'. As a result, this move actually looks pretty happy to me.
