Full board with full point mutual zugzwang I have two questions.

1) Is there a position with all pieces on board such that the side to move loses?

2) Is there a position with all pieces on board such that the side to move is checkmated in 1?

Regarding question two, here is one example position that I’ve made where the side to move is checkmated immediately, but the knights are still missing.

[FEN ""]
[startply "54"]

1. Nc3 Nf6 2. Na4 Nh5 3. Nc5 Nf4 4. d4 e5 5. h4 a5 6. Bxf4 Bxc5 7. a4 h5 8.Ra3 Rh6 9. Nf3 Nc6 10. Ng5 Nb4 11. Qd2 Qxg5 12. Qxb4 Qf6 13. Qc3 Qa6 14. Qh3 Rb8 15. Rg1 Qa8 16. Qh1 Ba7 17. Rh3 c5 18. Bh2 Ra6 19. f4 Kd8  20.Kf2 Kc7 21. g3 b6 22. d5 Kb7 23. Kg2 f5 24. b4 e4 25. b5 g5 26. c4 e3 27. d6 g4


Maybe, someone can improve this.
Here's a position with all pieces where either side to play loses.
Seeing why it's a loss takes some analysis.  With Black moving first, White's best plan is to open up the Bishop on f1 pinning the pawn, then Qxa4 checkmate.  This happens in most but not all lines.  Shredder evaluates the main line as +22, because either Nxc5 or cxb8=Q with leave White up a queen.
