That’s my spin of the whole idea, but since it originated from this thread, I post the results of my ventures here, to give credit where credit is due.
The concept is that since this is not immediately “squarish” the opponent doesn’t catch up early that a deliberate shape is being made and so far noone has interrupted the building of the parellelogram.
Also, I thought that since it is odd and not as clearly symmetric as a square, it will be more stable than a square or, at least, more intimidating. So far, noone yet has tried to invade it.
That game is also going well… I almost fumbled it, but at the moment it is heading for a very rare victory against a dan player. I am so excited, I cannot wait for the next moves in DGS, I kepp pressing f5 every ten minutes hehehe
And the stones of the fuseki? Surprisingly ideally placed!
If the opponent wants to invade it, for example at tengen, you can make good shape and turn the invading stones into a heavy weak group. The purpose of the square formation is to be strong in the area, you don’t need to fully enclose the territory inside of it:
Though AI is telling me Black has a better result after these moves, so maybe White should consider playing somewhere else instead of responding. All I know is I like the shape, and I would prefer to have this kind of center fighting instead of corner joseki and reading corner-based life-and-death.
2 is ok but 4 is really bad, forcing white to break your own shape. Better to tenuki, or at least play 6 directly if you want to connect your square without hurting the top left stone (but hane outside probably better).
