While running a game between the Interactive Diagram and Zillions-of-Games, I found a bug in the Interactive Diagram. Here are the moves. The last move has an illegal promotion. The White Cavalier moves to White's first rank and promotes. But promotion is legal only on its last rank.

  1. Cab4 Cde5
  2. Ma4 Ced5
  3. Mg3 Cc5
  4. Maa3 Nh5
  5. Mh1 Nxf1
  6. Nxe5 Cxe5
  7. Mxf1 Ccd3
  8. Cxd3 Pxa3
  9. Nxa3 Na5
  10. Nxe5 Mb6
  11. Cc4 Nxc4
  12. Ca1=M
