I found one (move 130):
Hardly qualifies as a sanrensei at that point.
Well, John did claim "even late in the game."
What a crazy game, how does that end as black +1? Amazing. Thanks, daaldude.

This seems quite reasonable and a useful general observation. Does there exist a thread where you and DrStraw have discussed this?
Thank you for the correct appellation. Bill seems to want to refer to me as
Dr. Straw , not
DrStraw .
Sorry, DrStraw.

As for your question, I don't recall a specific thread, more just comments scattered throughout the forum.

I'm a bit bemused by our apparent desire to call
... Strange Midgame Attachment a reasonable move.
Edit: I realise lots of people were expressing this tacitly, but I think we should be explicit here.

not good.

Hi Bill, how do you feel about this
extend instead of connect ?
(Because the solid connect
allows the big point
(a) in the above diagram.)

Thx Bill !
While we are with the sanrensei, what about just that simple
(Igowin plays that from time to time),
Is a reply at "a" or "b" correct ?

Hi oca,
at (a) is a standard beginner mistake. (I just saw this kind of move discussed in a review on KGS last night! )
at (b) is a much better reply.

Hi TJ, good question. That kosumi (diagonal move for Black) is also a better move than
(a).
How to decide between the kosumi and (b) depends on the whole board situation (as usual
).

There was a whole board in oca's post. What would you choose in that situation?

Apparently you meant the kosumi. But in case you meant the attachment, . . .

Indeed I did. But what you presented was very interesting, and I thank you for that.
