Even if the initial position weren't a little silly, 2. gxh4 isn't White's best move by any stretch.
Checkmate in ___ moves

Look below.
If it's black's turn, how many moves will it take for checkmate?
If you can't figure it out, look below!
1...Qh4 does threaten 2...fxg3, and White is dead lost, but it is no way a forced mate in 2.

I know that white can stop the plan.

Not to mention illegal.

Impossible for black to have two queens already, especially since all white's pieces are still on the first rank. Anyway, it's just a variation of the fool's mate.

Oh -- in the second diagram, yes, I was only looking at the first in which Black has seven pawns and two queens.

No, it's possible, just not plausible.
In the second game all of black pawns are still on the board.
It is true that, in the first, there is a pawn missing. But it is the a7 pawn while the only place it could have possibily been a promotion was c1, and there is no way it could get there without captures.

Yes, but white is also missing a pawn, which could have been promoted to a knight and then captured on g2 to allow the black pawn access to the back rank.

Oh -- in the second diagram, yes, I was only looking at the first in which Black has seven pawns and two queens.
How does white have all of his pieces still on the first rank and black obviously promoted to a queen? One of the white pieces would need to be displaced(which it isn't).

Well, they can leave the first rank and then move back to their starting position after the promotion, no?
