Question:
How would this situation develop from here? Which invasion was more sensible? Who has the better prospects to benefit from their respective invasions? Who has the best prospects of surviving their respective invasion?
I leave you with this rather obscure proverb: "He who is thick is often narrow, She who is thin is often wide.", which has atracted my attention as a curiousity. I don't know what it means, but it has often mystified me.
Double Invasion between two different types of frameworks.

Re: Double Invasion between two different types of framework
Your initial position has 8 black stones and 6 white stones.

Possibly a two-stone game with free placement.HermanHiddema wrote:Your initial position has 8 black stones and 6 white stones.
Anyway,
has room for two-space extension on either side while 
has room to run in the center. If I were white, I'd attack and defend in turn. If white didn't feel her invasion would live, she shouldn't have played it so she should trust her reading and not allow black easy life in her area.-

Re: Double Invasion between two different types of framework
Actually, it's research for a computer go engine I'm developing. Both frameworks were generated by fragments of code using two different algorithms. The first was, essentially, additive, territorialist, and nominalist. The second algorithm uses a unique method for calculating thickness that I am working on.
I'm still doing additional testing.

Re: Double Invasion between two different types of framework
The black algorithm needs some work. If there are no other stones touching the stone you are about to play, it is almost always a mistake to play stones on the second or fifth lines. Second line is too low and doesn't generate good territory; fifth line is too easy to invade. Black is also overconcentrated in the top. Despite the fact that black has a move advantage, white will probably win this game. I don't even like as an invasion - it would look much better at C14 or C12 then C13, as these are good points of invasion around fourth-line stones.

Re: Double Invasion between two different types of framework
I do not disagree with any of the comments so far, but I will attempt to answer the questions...at least the the second and third ones.oso wrote:Question:

"Sensible" is a tricky word. In terms of correctness, I prefer the white invasion. It is arguably the best invasion point in black's position, and it should not have much trouble living. The black invasion is not terrible, but there are many other choices that are at least as good, and perhaps better. Dealing with the white invasion, which numerically appears to be first, is more urgent than this invasion.
"Sensible" in the sense of survival prospects, or question two, is a different story. The white invasion, though correct, could probably come under a little more pressure, but not enough to die.

Re: Double Invasion between two different types of framework
Yes. If you notice, each of the black stones is on a column/row by itself with respect to the other black stones. It depends, but using both algorithms together does have its uses.

Why do you think that it's beneficial to have them on different rows/columns?

Re: Double Invasion between two different types of framework
Got three minutes left on the computer.
Essentially, the algorithm that generated the black sequence was not meat to generate frameworks. It was actually meant for something else... urm... It's hard to explain. Essentially, however, it helps with getting territory. A by product is really thin moves. hence the second algorithm.
gotta go. My time is up.
