Look at this great game by PlentyChess 4 in my 15000 games testrun.

3min+1sec singlethread, 6 moves UHO-openings (white is better!). PlentyChess 4 wins with black (!) and sacs its queen already in move 9 (!!!).

This one and 19 more great sac-wins by PlentyChess 4 can be found (and replayed) directly on my website:

it's a known queen sac , first played by Mchedlishvili(2609) - Ratnakaran(2338)
in 2019 (also won by Black), then three times at human masters level in 2022,
and next year in correspondence chess Knittel - Wong, ICCF, 2023.

The move 8...Nxd5! scores better than 8...Qxd5 but White still does not
have to lose ofcourse after this queen sac.

So what? The engines definitly did not know the queensac before (how should they?). Playing a queensac is very rare in enginegames and much rarer when it happens so early in a game (move 8/9).
So, it is a rare and great enginegame. And I never said anything else, or did I?
