After letting the engine sit on the position for long enough, it eventually comes up with an even stronger line: Rdf1. Not going into the forcing line with checks turns out to be better, because black can't deal with the pressure anyway, so white has time to add another attacker before moving ahead. Even with this "extra" move for black before the forcing moves come in, ...Ke7 immediately is too late, mate is inevitable.

Prime example of an engine move, I don't think many people would come up with it, especially since the position is already crushing.

I don't know how to read real chess moves.

But black queen must take (new) white queen.

It then seems foolish for white queen to take black queen, since black king must take white queen.

With the board state, white might find it advantageous to exchange queens with his board state, but I think white pushing white queen forward to take the black pawn in front of it would be the better move.

It’s neither, there is a better move that ends in winning blacks queen.

Stock fish can’t see it. But it’s all forced moves.

Oh so instead of white pawn takes black rook, you'd go white rook to g8.

This forces black king to f7. White rook takes black rook, putting black in check.

Black king can escape (which then has white rook takes black queen) or black queen takes white rook (with pawn taking queen and promoting).

Either way blood bath ensues, probably leaving white up some pieces for the exchange. Mkay, I think I see.
