value?

(Assume white cannot connect to the outside or threaten the life of the black strings.)

1. What's the miai value of W1 versus black playing there?

2. What's black's best continuation if he answers locally?

value?

Bill: Is it OK to alter the diagram like so? That's a much easier question to answer.

value?

Calvin: (11k). Yes, you can change it. However, now that I look at it more, there's a special sequence in the first example, so maybe it's not so good. To be specific, I'm just trying to gauge approximate value of ignoring a second-line block move in general. (If that makes any sense.) You can assume the right hand side of the board is infinite if that helps. Is this an easier one? Feel free to simplify it more, and maybe add it to the miai values list pages. If this situation is equivalent to one of the examples there and I've just missed it, let me know. It's most similar I guess to Corner12ConnectionValue, but with an open edge, and not just in the immediate corner, so intuitively I'd expect it to be larger than the 2.67 given for the corner.

Bill: Thanks, Calvin. I'm glad you are interested in an approximate value. These things are not so easy. (Comparable to the monkey jump in difficulty.)
