Take all the black pieces except for the King  and 
all the white pawns out of the board on initial position.
 
From this position White makes regular chess moves. 
Black King can jump to any unattacked square. 
Black King is not allowed to capture White pieces.
Check mate the Black King.
 
This has a 9 moves solution but less than 20 will do..

A sufficient condition for White to win is to attack every square.
If such a White position exists, get there in a minimum number of moves.
Since Black has access to any/every square on each move

Thanks, TSLF.

I don't see how Black can get stalemate in that sequence.

Spoiler for e.g.

I could not find the 9-move variation. :(

my blunder, Kg4 yes,  the black king is just there  for the play , i guess any solution can give continuous checks to ensure checkmate.
