(;B[qn]CR[qn]C[Theory dictates that approaching or enclosing a komoku corner is bigger than approaching or enclosing a hoshi corner, although the differences are subtle.  The reason is that a komoku is one move away from a complete enclosure, while a hoshi is two moves away.  See variation for example of a move that follows convention.]

;B[qg]CR[qg]
(;W[ql]CR[ql]C[This pincer is the wrong choice.  White should respond locally at Q15.  If white chooses to pincer, pincer theory suggests that the pincer should be loose, since white is entering black sphere of influence.  The pincer at R8 leaves black the ideal 2 space extension at R10, which leaves white with 2 weak stones at Q15 and R8, as well as an incomplete corner at Q4.  It will be hard for white to deal with this.  See variation for a better pincer.
]
;B[qj]CR[qj]C[Now white has 2 weak stones at Q15 and R8, while black only has 1 weka stone at R6.  THis coming fight will be good for black.  White should think about sacrificing R8 or Q15.  Running both will mean black will profit.]
