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

Take all the black pieces except for the King and all the white pawns out of the board on initial position.
Now play White on regular moves, ask someone lift up the Black King and place it anywhere safe
(e.i. unoccupied or unattacked squares) including its previous position.
Lets see how long will it take for you to capture the flying King..

Your light and heavy cheat coins weigh like 2 proper coins
but looks the same.They always hit the jackpot in any
slot machines. Drowsy, you accidentally used them on
a vending machine along with 2 other proper coins.
However the coins malfunctioned the machine causing it
to dispense hot cup of coffee with the inserted coin inside.
To test weights, you may insert a coin using the beam-
balance machine once.

from salty origin
many odor skin
so bitter bite
made drink bright
sweaty grasp
a leapy gasp
pretty color orb
smoothly curved
Like rock and
falls like sand
Like honey and
flows like cream
pain in the eyes
but healty sighs
thrown from atop
sounded a plop
