C[This is an aggressive move. A safe move would be at White A. ];B[of]
C[The correct response. ];W[oi];B[ph]LB[pi:A]
C[White should simply answer at A. ];W[og]
C[This attachment actually helped Black make good shape. ];B[pf];W[pg];B[qe]
C[Black has good shape. ];W[nf];B[ng]
C[The cut is a good move. ];W[oh];B[mg]LB[mf:A]

C[Black should move out at A. ];W[ql];B[pl];W[qn];B[rm];W[pn]LB[qm:A]
C[Breaking through into Black's side with good shape gives White an advantage. This was caused by Black's mistake at A. ]

C[With this move Black has to connect at A. ];W[pp];B[rq];W[oq]LB[nl:A]
C[Now that W has a strong shape here, breaking through at A has become useless for Black. ]

C[By cutting at A, White has made a play at B forcing for White. This prevents Black from cutting at C]

C[Black should now force with A to connect his stones; see var.]

C[Cutting off the Black group, White threatens to push through at A next. ]
;B[ko];W[hk];B[ij]LB[kp:A][gm:B]
C[This peep puts Black's center group in trouble. Black must play at A or B to escape. ]
;W[jl];B[jm];W[hl];B[hp]LB[gn:A]
C[Black is running in the wrong direction. Black A is correct. ];W[jo]
C[Although Black stills seems to have potential to live with this group, White already has a decisive lead in the overall position. ]

C[The final keima is an important move. B doesn't need to capture the 2 W stones yet, as the fight starting with White A, Black B is playable for Black. ]
