CHICKEN GOMOKU (a game sample)

Black must make a 5-in-a-row, White must prevent him.
Both players play black moves until one declares
to be black, simultaneously passing.
Then alternation as usual starting with white.

a b c d e f g h i J: d3,i7,a9,i9,c9,i1,J takes x
. . . . . . . . x 1. e4 d6
. . . . . . . . . 2. d4 f6
. . . x . . o . . 3. e7 e5
. . . o o x . . . 4. c6 c7
. . . . x x x . . 5. b8 f4
. . o x . x . . . 6. g3 f5
. . x . o o . . x 7. f7 g5!!
. o . . . . . . . 8.
x . x . . . . . x 9.

And, at this point, J wins in 5 moves. Can you see how? playing at h6,g6,g7,g8,g9/g4 (select the previous text to see the solution).

Black has more resources in this game now that he needn't worry about defending against white attacks.
