Dear retro friends,
A new update of the "Add units" booklet can be found here:
Modified N2Ai (previous version cooked by Mu-Tsun Tsai)
and 2A which was improved.
Regarding N2Ai, here's another version:
Alain Brobecker & Computer, Original 2011/04/04
It has 11 squares that are controlled twice, but i prefer
the one in the booklet since it has BK not on the edge and
7 squares controlled twice (no position with >7 has
solution with BK inside).
Best regards, Alain
