You need to win over three rounds, with three combat moves in each round. Note that there are three blank spots because you only have six total moves but nine places to use them:

  1. Sticks: Stab, elbow, punch. Counter with: dodge, block, elbow.
  2. Sticks: Stab, block, kick. Counter with: stab, [nothing], punch.
  3. Sticks: Dodge, elbow, stab. Counter with: [nothing], kick, [nothing].
