First moves are reasonably easy (white at
)
Next, the ko under the stones ( is the first incredible move;
takes back the ko at
)
It is a two-stage ko, so the fight spread to the edge... ( takes back
);
is an inner ko threat
takes back
,
takes back. Is Black out at last?
is the last important twist : if played one point left, Black can escape
All those antics won't save Black now
Moves ,
and
under the black stones (this is a two stones edge squeeze)
A fitting conclusion
