15+16. Shortest proof game in 2.5 moves (Dynamo chess)

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.
