1st British Championship
Shodans don't play like they used to, Thank Heavens! Jon and Colin
would be the first to admit that their play is only up to present-day
 standard. No matter. Nothing is as
incomprehensible as a game without mistakes.
Black: Colin Irving, 1d
White: Jon Diamond, 1d
Played at 'Pontefract Castle', London in Autumn 1965
The game-file in
Figure 1 (1-100) |
33 at 25, 34 at 29, 39 at 25.
- Black 13: When a move like 11 is ignored it is often very strong to
follow up with another. Black's corner becomes very large and strong.
- Black 21: The sequence to white 40, excluding 38 is the 'bread and
butter' tesuji. Note especially black 29, following the proverb: 'add a
stone and sacrifice two'. This tesuji is surprisingly common, against
the edge as well as the corner.
- White 44: A standard strong response to 43, which is too narrow an
extension from his very strong corner. 50 is better - a vital point for
reducing White's corner.
- Black 49: By attacking with a high 4th-line move, white has the
chance to slip under to 53 or jump to the centre. Black cannot stop
both, so white takes 50.
- Black 59: This capture makes black very strong, but white's shape
is almost perfect after 60. Not a successful attack for black.
- Black 61: His reward for 59 is an attack on 6-8-10 which will be
driven towards the black ponnuki.
- Black 83: This turns out badly. Black above 77, white 84, black 85,
white 83 produces a similar shape without sacrificing a stone. But Black
has problems anyway. He would like to steer between the two White
groups, then turn and attack the upper group - but he has already made
that group too strong.
- White 90: White 88 weakened black 45. White expands his side
upwards and is now attacking black.
Figure 2 (101-206) |
132 ko at 126, 134 fill at 125, 139 fills ko at white , 154 fills ko at
147, 195 ko at black , 197 fills ko at 186.
- White 118: Greedy. 119 is the focal point of two moyos. Whoever
plays there first will expand his own area while reducing his opponents.
- White 120: Even greedier. Black 121 is a tremendous move, forcing
White back in bad shape.
- Black 123: Naturally; now White's group is in trouble.
- Black 131: Black's reward is a ko, but this is a bad ko threat -
because it only threatens another ko. He should threaten white's right
hand group, or break into the giant left hand corner.
- White 138: White exchanges his threatened group for cutting off the
black centre stones.
- Black 151: Black makes a sort of breakthrough, but in the following
sequence can only struggle towards a single eye.
White wins by resignation.
