White can stay connected to the K-edge at the cost of Black getting H4.

(White will need that to escape a ladder towards K1).]

Black should've played in the A1 half of the board, since this lets White reconnect to the K-edge with...]

This seemed very good for me at the time, due to the ladder escape fork at B10, but actually, Black is winning now.]

Excellent move.

I think Black should've continued with the joseki.])

Assuming Black does tenuki (play elsewhere), Black should seek more from this move.]))
