;W[ql]LB[pn:A]C[Although it allows black to play 13, this move is good. If white plays 12 at 'A', then black can play at 12 with good feeling.]

;B[pm]C[To diconnect white by playing sagari from 17 is also a viable way of playing.]

;B[cf]C[This is a strong response to white 56. To play at 65 would give white a better chance of making life among the side.]
;W[ff]C[Not good. White has little chance of success with a direct manoeuvre. He should play more lightly around 72.]
;B[gg]C[This move should be at 64, Black's stones at 23 and 53 are not important, and more attention should be paid to securing the centre. ]
;W[cj]

;W[dk]
;B[bk]LB[cl:C]C[It is more natural to play at 'C'. After the sequence to 69, 'C' would have been a much better placed stone than 63.]

However had white played 118 at 120, followed through with the sequence to 125, and then played 'E', forcing black to connect with 'F', he would stand far more chance of making a second eye for his group or escaping. ]
