C[1-24: Reasonable for both - Although Black gets two shimaris,
white 22 is an excellent point (Black could consider playing
21 one point to the left of 22).

C[White 28 is a bit strange - the usual idea is to play hane at
'A' instead. 28 would make more sense if white 6 were one line
closer, but the shape in the game leaves Black with good chances
to invade the side later.

C[Jim grabs his fourth corner - this play may look small but it
is essential. Once the corner is secure it becomes relatively
easy to live in the centre.

C[Bad - he obviously feels that he is strongenough in this area
to kill White completely, but the game sequence leaves many weaknesses.

Dia 1shows the obvious sequence White gets a favourable ko (if
he wins it with 'A', he can continue at 'B'). Black can do better
than this by playing 4' at 5, but the result is still ko (exercise
for the reader).  

If Black had played 49 correctly at 'X' in the figure then there
would be no chance at all for White to live in the corner, and
Black's stones 23 and 47 would be nicely placed to trap him if
he tried to run away.

C[White 54 threatens to surround the centre on a large scale. Black
55 is a good, light invasion, but 57 is an overplay - he must
settle himself in the centre before playing here.

C[Black 69 is reasonable, but 71 is not. It is neither necessary,
sufficient, nor indeed possible to live so deep in the white
moyo.  

Even after 73 Black can cut his losses and abandon these stones
for the moment. Jm Bates is quite strong enough to know this,
but he fell into a common psychological trap, letting himself
continue with a bad sequence even after he knew it was bad. It
is extraordinarily easy to do this the sensation is rather like
a bad dream - you just sit and watch your hands playing a string
of ridiculous moves and are quite powerless to stop them.

C[Now it was Richard's turn to err despite himself. He had spent
several minutes thinking about 76, but had clearly not thought
about the consequences of black 81 while he was doing so. Nevertheless,
when 81 was played, he replied at 82 after about half a second's
thought. Had he devoted an extra few seconds to the problem,
he should have had no trouble in spotting that 83 (A)would be
a much better play than 82. this makes miai of 82 and 121 (B)
and kills the black stones cleanly.  Again the problem was not
in knowing what to do, but in actually doing it.

C[However, Richard was in byoyomi by now, and this is the blunder
Jim was waiting for. It gives Black time to connect his group
together. Now the capturing race is looking close.

C[Richard felt that this was necessary to keep him ahead in the
capturing race, but it fails simply to the sequence to 135. 
(after 135 Black kills three stones below or five stones above).
White 134 should be to the right of 133, but that gives Black
his extar liberty anyway.
