Can any engine find the winning move here ?

[Chessqueen]

This is NOT a troll, it is a position from a game played by in the 40'. Can any engine find the best and only winning move here? I left Stockfish 13 NNUE for 6 hours and is still looking for the best move, probably somebody with a super fast Machine 6 to 8 times faster than my intel i7 4770 3.40 GHz can find it in less than 30 minutes

I didn't check it in all depth, but Black Diamond v13 found 1.Qxe5 fxe5 2.Rf1 in 15 sec. After 10 Min it's at +4.30
My PC is a Xeon 12 Core with 3.40 GHz

This is NOT a troll, it is a position from a game played by in the 40'. Can any engine find the best and only winning move here? I left Stockfish 13 NNUE for 6 hours and is still looking for the best move, probably somebody with a super fast Machine 6 to 8 times faster than my intel i7 4770 3.40 GHz can find it in less than 30 minutes

That is Correct, I am surprised that Black Diamond found it. Here is the Link where I saw it 3 years ago ==>

Well, the queen sacrifice (move 24) was not a winning move.
White only won because 29....a5? was a mistake.
(cxb3 would lead to a draw).

But before the queen sacrifice the position move 23 Qd5!
would be winning, instead of the sloppy 23.Qxd6?!,

PS yep i used an engine

Just by looking at the position I believe that if the Queen move to 25.Qd5? the Rook will simply take the pawn losing momentum of the attack, and if the White bishop move to d1 then the Black King will move to f7 don't you believe ?
