Here is the proof game, exhibiting many weird Dynamo moves:

1. Bc1-e3 (Pd2-h6)
wBc1 moves and pushes.
1 ... Qd8-d6 (Pd7-d2)+
bQd8 moves and pushes. The wK is in check because bPd2 threatens to push him out.
2. [Nb1-push:] (Pd2-f3)
wNb1 pushes but remains stationary.
2 ... Qd6-c6 (Ph6-d6)
bQd6 moves and pulls.
3. Qd1-off (Pd6-d2)
wQd1 moves outside the board and pulls.

The wPd2 made a roundtrip.
