;W[ld]C[This is probably not a fatal error, but it should be on the third line in order to prevent Black from making a base.]
;B[gc]
(;W[hd]C[This move looks very strange to me in retrospect. It aims at cutting the black stones apart, I guess, but seems like it creates more problems than it solves. My next few moves all were aiming at the wrong thing (containing or cutting rather than preventing the formation of a base). Black has nowhere to run so that's the only concern.]
