Recap of 2023-02-08
Research the move after Small-Knight Approach to Star, One Space Pincer and 3-3 joseki.
(Theme)
The Joseki of the right bottom corner appears frequently regardless of the player’s rank.
Since the form of the left bottom corner is also natural in response to the right bottom corner, it is possible to appear entirely bottom side of the board.
As in this case, it is very useful to research in advance the position that appears frequently.
Let’s research what to move in this position with AI.
(Process)
Against the Small-Knight Approach (w8), black chose the One Space Pincer (b9).
And until w18 is a basic joseki which often appears in actual games.
Following it, black approached in the left bottom corner (b19) and enclosed right top corner(b21).
(Recommendation move by AI)
w1 is the move AI recommends.
This is the move that changes the next one according to black’s move.
(Ordinary progress)
Against the white’s ×, it is ordinary for black to jump as b1.
Then white will guard left bottom corner (w2).
(Following)
Following it, if black reinforces the left of the bottom of the black(b3), they will compete like until w12.
(Another progress)
Against × of the white move, if black moves left bottom corner, white will get sente and move right bottom.
Then w8 is the famous move as an aim after this joseki.
Against w8, possible black move is A or B.
(Not good for black with white’s sacrifice)
It looks natural to watari. But this is not good for black.
Against w2 black will cuts(b3) or so, then white will sacrifices , get sente and move w10.
It is to white’s advantage.
(Black’s sacrifice)
Black is wise to sacrifice two black stones(x).
White can capture them, but black can move b9.
This is even.
(Progress of the actual game)
In actual game white (who was me) took priority to the upper side.
AI-sensei considers this is doubtful.
And since black could move bottom of the board(b8), the opening of this game became good for black.
