Day 68: Some things about fuseki V: Shimari

Back to fuseki, let's talk about shimari. The most common shimari is the keima for the 3-4 point (Point 5-3). Again, this is about 8 formulas:

In 19x19:

103=(n+1)*5+3
65=(n+1)*3+5
117=(n+1)*6-3
74=(n+1)*4-6

283=(n+1)*(n-5)+3
324=(n+1)*(n-3)+4
297=(n+1)*(n-4)-3
335=(n+1)*(n-2)-5


I think that this will be valid only for boards... let's say... bigger than 13x13.

So, if a stone is played in a komoku, maybe a shimari is a good move.
