puzzle 5 stones
-
Version
007
Make 5 stones at one line. Build five black stones at
one line. You need to build 5 stones on vertical,
horizontal or diagonal line. Do not build five white
stones. Unlike the case of five stones on the second
line in the corner, ... Even if the extra black stone
is one line away, Black can still kill using the
small. The best black can do is to make a small
reduction in sente. ( can also be played at a, but
that gives white an extra ko threat.)
