You have to read the 'Rules' section as well as the 'Setup' one. 'ABQ ... pieces ... can cross the River orthogonally or Knightwise but not diagonally or Camelwise.' In other words, the River blocks the Tanks from capturing the Queens as Arrows. Conversely you can safely advance the relevant Princeling leaving your Tank safe from attack by the Queen moving as a Bishop by the same River.
I will get on to the Knight issue when I have had time to analyse it offline.
