Because there is no common [[hex (board element)|hex]] used in both threats, Blue cannot prevent Red from connecting to the bottom.

For a blocking attempt Blue has to play on the overlap field:

<hexboard size="4x5"

  coords="hide"

  contents="E *:a1 E *:b1 E *:c1 R 4:d1 R e1 E *:a2 E *:b2 R c2 B 1:d2 B 3:e2 E *:a3 R 2:d3 E *:e3 E *:e4"

  />
+
 
+
Red is now connected to the bottom by [[Edge_template_III2e|III-2-e]].
