Andernach chess proof games

In December, I already drew your attention to orthodox proof games. Of course, you can combine this stipulation with a fairy condition, e.g. Andernach chess. Here are some examples:

  SPG in 9,0 moves(16+11)  
  Andernach chess

Solutions:
1 1. Nf3 Nc6 2. Ne5 Nxe5=w 3. Nxd7=b Nb8
2 1.2.1... means that the solutions splits at the first Black move, there are two (unique) continuations.
1. Nf3 d6 2. Ne5 dxe5=w 3. e6 Nd7 4. exd7=b e5
1. Nf3 e5 2. Nd4 Ne7 3. Nc6 Nbxc6=w 4. Nxe7=b Ng8
3 1.d4 Nf6 2.d5 Nxd5=w 3.Nxe7=b Ng8 4.c4
1.c4 e5 2.Nc3 e4 3.Nxe4=b Nxd2=w 4.Nb1
4 1. e4 d5 2. e5 d4 3. e6 Bxe6=w 4. Bd5 Qxd5=w 5. Qc6+ Nxc6=w 6. Nb4 0-0-0 7. Nd5 Rxd5=w 8. Re5 d3 9. Re2 dxe2=w
After a long journey, the wPe2 returns: P->B->Q->N->R->P.
