1. A cannon and one advisor vs Two advisors

   1.Ge3 wins an advisor: 1...Gd9 runs into 2.Ae2#, and after 1...Ge10 2.Cxd8 the recapture is illegal because the advisor is pinned by the facing generals.

2. A cannon with all four defensive pieces vs All four defensive pieces

   A cannon needs at least an extra soldier to break the full defence.

3. Horse and cannon, both sides with four defensive pieces vs A horse

   Horse and cannon, both sides with four defensive pieces vs A horse

4. Horse and cannon, both sides with four defensive pieces vs A cannon

   Same attacking material, and the defending minor piece alone flips the result: a cannon holds where a horse does not.
