Bigmouth stroke again - some chess buddies asked be about the helpmate
from starting position where the sum of the (standard Euclidean) move lengths is minimal.
I referred them to PDB, but it seems tougher than expected to find the problem.
This is what I found elsewhere:
https://www.quora.com/What-is-the-minimum-possible-total-distance-covered-by-White-and-Black-pieces-in-a-chess-game-in-which-White-checkmated-Black-from-the-initial-position-The-figure-is-always-in-the-center-of-the-cell-The-size-of-cell
Which is of course wrong.
1.d3 (1) e6 (1) 2.Dd2 (1) e5 (1) 3.De3 (V2) Ke7 (1) 4.Dxe5 (2) ~ 8.4 is already better.

1.f3 (1) e6 (1) 2.g4 (2) Qh4 (V4) ~ 6.8

V8, not V4 ;-) But your number is correct.
The usual smothered mate 1.e3 (1) Sc6 (V5) 2.g3 (1) Se5 (V5) 3.Se2 (V5) Sf3 (V5)
is still shorter (~6.2), but I think this isn't the solution either.

No, my correct number is 9.7.
Your's is 10.9.
