Okay, I see, you just have to give the King room to avoid the stalemate and bring down the pawn to queen.

White to play and mate in 3 you must sac the Rook.

You left one thing out -- the funny counting.

(I'm too dumb to get the pgn to work)
The trick is to "pass" and force the king to move to where he has no escape squares from a check after it moves. The king is lured into a mate, not forced into one.
Think about where the black king can move now, and then think about where you can shepherd it so that the second move is a mate.
The correct move is to offer the bishop with 1. Be5. That leaves the black king with only two choices- to capture the bishop on e5 or the pawn on e3.
If 1. ... Kxe5 then 2. Qe6 mates. If instead the black king takes the e3 pawn, then 2. Qf4 mates.

To the Chess Praxis problem
What happens when 1.Qg7 Kx 2.h6 Ne6?
Surely the pin is then broken and they're forced to take the Rook and stalemate is avoided...?

2.h6 is check, black has to take or get out of check. After which white has no legal moves.
In my first solution, I just sacrified the white rook. Then I thought from your previous solution to the Exuma problem, you must have something tricky in mind, so I edited my solution to sac both rooks. Of course, you know I believe the defender doesn't have to take the rook, since that is not specified. 😏
P.S. However, 3-movers are much easier than 6-movers and there is not enough moves to allow for that funny arithmetic.
