Subject: A bug in Rebel 9 (2)

I am sorry. I wrote the move 19 wrong in my first report of the bug in
Rebel 9. I try again.
If you make the moves as below with feature player-player in Rebel 9,
then take the moves back one after another, then you have two kings when
you come to move 19. The same thing happens in Rebel 7 and 8.

1.  e2-e4    e7-e5   2. Ng1-f3   Nb8-c6    3.  d2-d4    e5xd4   4.
Nf3xd4   Ng8-f6   5. Bf1-d3   Nc6xd4    6.   O-O     d7-d5    7. Nb1-c3
  d5xe4   8. Nc3xe4   Nf6xe4   9. Bd3xe4   Bc8-f5  10. Be4xb7   Ra8-b8
11. Rf1-e1+  Bf8-e7  12. Bc1-g5    f7-f6   13. Bg5-e3   Rb8xb7   14.
Be3xd4     O-O   15. Qd1-f3   Rb7-b5   16.  c2-c4   Rb5-b8   17. Qf3xf5
 Qd8xd4   18. Re1xe7   Rf8-d8   19. Qf5-e6+  Kg8-h8   20. Qe6-f7
Qd4-d1+   21. Re7-e1   Qd1-d2
