Arbiting an IM norm tournament last week I came across this position in one of the games. Both White's queen and bishop on a4 were en prise and it was Black's move!
My initial reaction was that I must have missed a touch-move violation which the players had sorted out themselves. Next I wondered why White hadn't just resigned. Finally, when I saw that Black was deep in thought, I wondered why he didn't just whip the queen off immediately.
[Title "Jonah Willow vs Neil Berry 4th EJCOA IM 2022"] [fen ""] [Startply "19"] 1. Nc3 Nf6 2. e4 e5 3. Nf3 Nc6 4. Bb5 Nd4 5. Ba4 c6 6. Nxe5 d6 7. Nf3 Bg4 8. d3 Bh5 9. Rg1 b5 10. Nxd4 Bxd1 11.

As you can see, White went on to win. Overhearing the postmortem, Qc8 was a mistake. Qd7! would have been better and, according to the white player, the computer gives a long line ending with an evaluation of 0.00. Quite remarkable.
What is the history of this stunning queen sacrifice?
