1st place:
1. d4 c5 2. dc5[+bPc7] a5 3. Qd5 Ra6 4. Qh5 e5 5. f4 Qf6 6. fe5[+bPe7]
Qf1[+wQd1] 7. Kd2 Qf3 8. g4 Qc3 9. Kc3[+bQd8] Rd6 10. Sf3 b6 11. Rf1
Rd1[+wRh1] 12. Sd4 Bb7 13. Rf5 Bh1[+wBf1] 14. Bf4 Bb7 15. Sd2 Bc8 16.

Bishop f1 has to be removed temporarily, and black has to capture it
thrice, resulting in the circuit Bf1->Qd1->Rh1->Bf1. Black's capturing
pieces return to their home squares, unfortunately not fully analogously.

2nd place:
1. e4 d5 2. Bb5 Qd7 3. Ba4 Qb5 4. c4 Bg4 5. cd5[+bPd7] Bd1[+wBf1] 6.
Kd1[+bBc8] g5 7. Kc2 Qf1[+wQd1] 8. h4 Qb5 9. hg5[+bPg7] Qb3 10. Kb3[+bQd8]

Clear twofold representation of the same theme shown in the first place
problem. White's 10 moves are apparent from the diagram position. But
the white queen is in the way, so black has to capture it and make it
reappear on d1. The white king makes sure that black's capturing pieces
return home.

3rd place:
1. d4 e5 2. Be3 ed4[+wPd2] 3. Qc1 de3[+wBc1] 4. d4 Se7 5. Be7[+bPe7] e5
6. Sd2 ed4[+wPd2] 7. Rc1 de3[+wBc1]

The way in which the pieces disappear is typical of Circe Assassin. The
set theme appears as if by coincidence.
