fernobob:Recently in a handicap game as black I was faced with this joseki variant. I considered responding at a, but this seemed a little slow and could cause my corner to become enclosed. In the end I responded at b, intending to split the white groups apart, but as this resulted in my corner dying, I suspect it was not the best move. What should I do here?
Bill: Black has various options, including a to f. A lot depends upon the rest of the board, but Black can play at a or b to keep the White stones separated and attack both at once. He can also play at c,d, or f to secure the corner and attack the base of at the same time; these plays also prepare to attack both White formations. c and f threaten g. e attacks Black's larger group, and White's stones are still not connected. However, e can lead to more complications than the other plays.
