C[Playing under the starpoint is often seen in recent games. Previously, a play at "A" is more common, but that would tend to lead to an attack on the upper side. I agree with B9 because it provides more room on both sides. ]

C[B has the option of avoiding the fight altogether by playing the variation beginning at A, but in the game, B accepted W's challenge]

C[In this fight, the marked W stones have become heavy and this now seems to have become a dangerous fight for W. No further comments]

(;W[gc];B[id];W[hf]
C[this is a better attack, because B does not have eyespace and the marked stone is relatively light and W can afford to throw it away]
