===Puzzle 1===

<hexboard size="4x4" 
  edges="hide"
  visible="area(a1,a4,d1)"
  contents="R a1 B b1 R 1:a3"
  />

===Puzzle 2===

<hexboard size="5x5" 
  edges="hide"
  visible="area(a1,a5,e1)"
  contents="R b1 c3 B d2 1:b2"
  />

===Puzzle 3===

<hexboard size="6x6" 
  edges="hide"
  visible="area(a1,a6,f1)"
  contents="R a2 c1 B b4 1:c2 R 2:d1 B 3:b2 R 4:b1 B 5:e2"
  />

If Red plays e2 too early on move 3, it is losing. If Red 5. b2, then Blue 6. d2. If Red 5. d2, then Blue 6. b3.

<hexboard size="6x6" 
  edges="hide"
  visible="area(a1,a6,f1)"
  contents="R a2 c1 B b4 1:c2 R 2:d1 B 3:e2 R 4:c3"
  />

If Blue plays 2. c3 instead, Red's unique winning reply is 3. b2!

<hexboard size="6x6" 
  edges="hide"
  visible="area(a1,a6,f1)"
  contents="R a2 c1 B b4 1:c2 R 2:c3 B 3:b2"
  />
