C[White 18 - Black 21: I think it is better to omit this exchange,
since white loses the possibility of a ko later on. (R) The ko
arises if white plays 20 one line higher, after the exchange
to 24. Then if black extends 9 along the third line white can
pull out his dead stone 12 in the corner (E).  
];B[rp];W[nq];B[qr];W[mp];B[iq]
C[Black 25: This move is OK but black should expect white to invade
in the middle of the extension immediately. (E)

C[White 34: This move is hamete. Doubtless I would have fallen
into the trap had I not done so already at Linz! (R)

C[Black 53: A small mistake - Black should simply play 55. If White
replies with 56, then the cut at 54 looks better than 53; if
white 53 instead, then black 57 moves out slightly faster along
the side. (E)

C[White 62: This is a reasonable result for White as black’s corner
is about 25 points and white can start a multi step ko by playing
on the corner point. (E) 
];B[pf]
C[Black 63: Awful - A is the only move. White cannot achieve a
great deal in the top right. (R)

;W[eo];B[fp]
C[Black 65: A bad exchange for 66. Black should reduce the left
side (where?). If White invades at 69, Black can handle the situation
with moves such as B and C. (R)

C[Black 73: Too deep. It is important for both players to count
the game before this kind of play. Black would discover that
a shallower invasion was sufficient, and White would discover
that it was necessary to capture 73 by replying with 91. Therefore...
];W[gj]
C[White 74: Too slow, He must play 9l and try to capture 73.  Eventually
73 did die, but more by Black’s efforts than White’s. (E)

C[White 84: It should be clear that White has to cut off Black’s
centre stones to win. The next few moves show White successfully
persuading Black to let this happen. (E)

C[Black 101: Very slow, By now Black needs something more imaginative.
