recently.

at 23!)

C[White 42: Good, the only possibility.

C[Black 43: Bad - this leaves a weak point around 46 (A). Black
39 was a passive move and this 43 is too aggresive, so Black's
plan is inconsistent.

C[White 44: Not so good, the shape 38, 40, 44 is usually poor.
(This shape - the 'sake bottle' - lacks eye-making potential.)
44' should be at D.

point on the board.

C[Black 79: (John thought his moves 79-83 were sente and was surprised
by White's tenuki at 84. What would have happened if he had been
able to play here first again?)

he would lead.

is painfully weak.

correctly, otherwise his group is dead.

C[White 182: Not necessary. If Black plays 182, white B is a must.
Should White play at A then black B and all is lost (white C,
black D).  Anyway, there are possibilities here, but 182 is unnecessary
at this stage.

C[Black won the ko at 189 and that at 301, which is not shown in
full, to take the game by 1 point. This was an excellent result
for John as Miss Miyashita is a very strong player, though she
was tired by travel and a little unlucky in the game.
