i noticed that catharine was using a symmetry-based strategy until the
`endgame'; on paper, i had the following idea for winning (A, B, ... are
my moves; a, b, ... are catharine's, and c+/c& are potential moves):
. c . b .
a
. . .
A D
. B . C .
from which point i win. however, she doesn't allow the game to get in
this state; what happens is:
. . b .
a
. . .
A c*
. B . C .
so i played around some more, and won using
. b . .
c a
. D . .
A C
. c+ . B .
and also
. b . a .
c
. . .
C D c&
. A . B .
so my (linked) questions are:
why does catharine break the symmetry strategy by playing c*?
conversely, why doesn't she break the strategy & play c+ or c& to win?
i'm thinking it's something to do with corners...
