Strategy Y *
if there is an empty key position left then
(a)
if there is an empty key position on the circle where the opponent
took a key position in his last move then
if there is only one point in that circle then
assign the number of key positions for this circle to dN/K"∣
place a point on a key position in that circle next to the point
placed by the opponent on the clockwise side of that point (if
possible), otherwise on the anti-clockwise side (if possible)
_ otherwise anywhere else
else if there is an empty key position in a non empty circle then
place a point on a key position in that circle
else if number of empty circles L ≤ K - N mod K then
place a point on an empty circle assigning the number of key
_ positions for this circle to bN/KJ
else
place a point on an empty circle assigning the number of key
_ positions for this circle to dN/K^∣
else if if r < Z then
(b) |_ place a point in the middle of a maximal interval of the opponent
else
(c) if there is more than one interval of the opponent then
place a point in the middle of a maximal interval of the
opponent
else if there is exactly one interval of the opponent and its length
is l then
place a point in a bichromatic key interval at distance less
_ than 1/dN/Ke — l from endpoint of the opponent
