What’s the most possible checkmates in one, but with no promoted pieces, in a position?
$begingroup$
What is the most possible checkmates in one without promoted units in a position?
Consider this a part two of this question: How many total checkmates can you possibly make against the enemy king
Promotions are allowed in the game, but the position is not allowed to start with promoted pieces. Promotions count as one move, regardless of promotion type, per pawn.
I have found 37. I have modified the position made for the record for most no promoted units, all possible moves a forced checkmate, made by Harold Holgate Cross. (see it here: https://chess.stackexchange.com/questions/24033/a-position-in-which-checkmate-is-forced-obligatory/24067.)

See if you can beat that!

If the rook d2 moves to another square of the 2nd file, that's not checkmate as the king will be able to move to d4.

After looking at Araud Mortier’s position, I found one better.

The move dxe8=Q or dxe8=R adds one more for a total of 38. I shall keep his answer checkmarked though, out of respect.

If the rook d2 moves to another square of the 2nd file, that's not checkmate as the king will be able to move to d4.
