I thought about this move the other day.
eg. if the opponent approaches high in a nirensei, like this, there seems to be the idea of bumping.
– and playing as so:
– or like this:
I think the issue is in the second variation. In comparison to this line, it’s as though White continued by exchanging an endgame move around A for this nice point at B, making the result a bit unbalanced.
I think that if we were to see any of those results visually without any numbers and without knowing who has sente, White would have had a good result. But with sente always landing on Black, I’d be happy with any of thouse results as Black.
This is too deep to me, but i will try.
My fear is bump typically is considered a bad move. What if black tenuki or do a lower knight approach from other side?
To me the 2-3 exchange in both diagrams looks like a clear loss for white in the end results and I don’t really see how white has recovered that loss.
So from the 1-2-3 principle I would guess that (in both diagrams) playing 4 without exchanging 2-3 is already an improvement.
If Black plays another approach then I think this is fine for White:
Josekipedia actually has this move as a situation move.
Josekipedia has everything.
