Not a professional player, but someone judge my strategy:

White queen takes black queen, black king takes white queen, white king then moves into position to block black pawns from reaching the end of the board. Black king cannot move into check, black pawns cannot move to the side. Stalemate.

If you move your king away to the corner, then black either has to leave their queen unprotected, or take yours and accept a stalemate (best move for black).

Quite a tricky one. I got so tunnel visioned on trying to block the pawns, but ultimately realised it was futile.

I think you’re right. Looks counter-intuitive because trading queens puts the black king in the perfect position to capture our pawn, giving black two passed pawns against a lone king. Didn’t calculate it all the way through, so I don’t know whether it’s black or white who’s going to be stalemated.

Funny that stockfish suggests black makes a stalemate.

But that won't work either. Black will find an opportunity to either swap the queens without a stalemate or get one of their pawns through.

I'm not sure. Black king rushing to 2-row could stop white from reaching C1 by moving to B2. Without occupying C1, white cannot stalemate.

Now what if white plays King to H1. Black queen cannot capture because that's a stalemate, and cannot get out of the way because it's a check. But I'm not sure how the game goes from there.

Their queen is pinned to the king, so they either: move the king away and give you the queen, move the queen towards your queen and give away their queen, or take your queen and force stalemate. There are no other legal options.

Oh. Right. Sneaky little bugger.

If Kh1, Black loses if they don't accept the stalemate. It's otherwise zugzwang, any move besides Qxf2 results in losing their queen.

If you click onto the Lichess analysis board linked, the second button from the left on the bottom-right panel lets you play the position against the computer. Try it and see if you can actually prevent the pawn promotion that way...

You mean away from the corner, right?
kF1

No, kh1

But Qxf2

Look at Kf1, black has to back the king off. Queen capture is unavoidable

Yeah, but Qxf2 is stalemate, hence you don't lose
