C[9, 11: It is wrong to give the opponent secure territory on the
fourth line at the start of the game.

C[Trying to live locally is bad - simply jumping out to 28 (A)
is quite sufficient to punish Black's poor play.

C[Better at 25 (A).

C[18, 20: These moves make Black much stronger without helping
White.  
];B[od];W[pc];B[ob];W[lg];B[oh];W[li]
C[It is usually incorrect to follow a knight's move with a one
space jump because of the cut at 25 (A). White should play 36,
29 or 27 (/[\]).  
]LB[lf:A]

C[Black 25 - 31: These moves take full advantage of White's error.

C[White cannot afford to connect at 39 (A), since the ladder does
not work. Black would answer at 40 (B) and be able to handle
the fight.

C[Must connect at 58 (A) immediately.  

]LB[kc:A]

(;B[nk]
C[Bad - Black should cut at 58 (A) - threatening 55 which reduces
White's group to two liberties.  Then she should cut at 51 (B),
keeping the option of cutting at 50 (C) in reserve. After white
50 it is possible to play 54.

C[Should still cut at 58 (A).  
]LB[kc:A]
;W[le];B[ne];W[kc];B[mb];W[mc]
C[60, 62: Makes sure of the capture. The white corner is enormous,
but the game is not over yet since Black has a lot of thickness
in the centre.  
];B[ic];W[lb];B[cg]
(;W[eq]
C[Better at 65 (A) - Black 65 and 67 (B) are good and threaten
to take a huge side.

C[Too deep - a shoulder hit at 83 (A) is preferable.

C[Appalling - must hane at 80 (A).  
]LB[dm:A]

C[Lets White off the hook - 80 (A) would kill most of White's invading
stones.

C[Ambitious.

(;B[in]
C[Too passive. Black should shut White in more tightly with 94,
which also restricts his eye space a bit.  
]LB[il:A]
;W[il];B[ip];W[ii]
C[96, 98: Horrible aji keshi moves. The main thing White had to
look forward to in this area was pulling out his cutting stones
at 99 (A).

C[Bad shape and dangerous - should be 109.

C[Should cut at 118 (A) - White will have to make eyes in the centre.

C[Aji keshi - she could play 114 (this is why 108 was bad).

C[White is slightly ahead if he just hanes at 141, so this invasion
is wrong.

C[Better to peep one point above 150 (at A).

C[A reasonable try, though he should die here.

(;B[dd]
C[At the last moment Black loses her nerve and lets white live.
The hane above 150 (at A) actually kills very easily.

C[White 156, Black 159: White contrives to live in sente.

C[Taking this point gives White a clear-cut victory. The final
margin was 19 points.
