;B[md]C[The opening is very unusual. If my database is correct, it was never played by professionals]

;W[sb]C[White is alive, but Black's wall is quite strong and he is keeping sente. The result seems to be equal]
;B[qo]LB[pj:A]C[This move is too far from the wall. I would prefer to extend around A]
