This week's joseki demonstration will be about how to deal with the double knight's approach to the 4-4 point.
So in the case below, you have 4 choices of responses and we'll go over all of them and come up with the best one at the end.
So A is to escape outwards towards the center through a diagonal at 5-5. As you can see, what was once an acceptable outcome for black has changed as our modern joseki evolved and taught us to either build strong influence or to settle for safe territory on the sides or typically in the corner when playing joseki. In this case, white has both gained 10 points in the corner, has influence on the left side, while also still having aji on the top to escape the one white stone. This result is unacceptable for black.
The next plan black has in mind is to settle at B. However, this result is also unacceptable for black as white's move at 5-5 completely seals black in and leaves white with a strong central influence while black has only some 6-10 points in the corner. (The difference between this and the example before is that black is completely sealed within and white's influence is strong)
The next 2, C and D, in this instance are actually both playable because of black's small knight's attachment to the lower corner. If it weren't the case of that move, D would be the better option.
So how come this is the most acceptable outcome for black? Well as you can see, the result for black in the diagram above is certainly better than the previous examples. Black is able to build some influence on the right top side while also having quite a nice base in the corner. It is true that there exists a cut between black's stones in the corner, however the key here is to jump onto white's stone at 4-6 instead of connecting.
In this diagram above, we can clearly see that black and white both settle quite well and it definitely looks playable for both sides, although the knight's move approach on the left lower corner certainly feels a bit awkward now.
So that's it for this week, I hope this was helpful!
