Thanks for the game. I imagine there might be positions worth investigating that I have not analyzed yet.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I see that this game does not have the queen sac/weird imbalance. I am looking at just those right now

Yes, because it's the Scandinavian start where 4... Bg4 is a blunder, so a good Black player will play 4...e6 and there's no opportunity for White to sacrifice.

I was just (not thoroughly) looking for a game where it even got close to the line appearing OTB.

It looks like Smagin erred with 24...b5? instead of ...Nxg4, but White needed to play 26.Bd3 instead of Qxa6 to punish him.

There is a very similar line.

1. f4 d5 2. Nf3 g6 3. e4 dxe4 4. Ng5 Nf6 5. Bc4 Bg4 6. Bxf7+ Kd7 7. Qxg4+ Nxg4
8. Be6+ Kc6 9. Bxg4 *
Yes, this looks like it might have some chance of appearing OTB.
SF, depth=27, evaluates this as (-1.99) with PV 9...Bg7 10. Nc3 h6, etc.



Here's a game in this 1.f4 line that White wins with the sacrifice.




SF at low depth dislikes 9...e5 and thinks 10...Qf6? is bad (a draw).
After 12. Nc3, SF's line at low depth is
(0.00) 12... Qd8 13. d3 Nc6 14. Be3+ Ka6 15. O-O Nxe5 16. fxe5 Bh6 17. Bxh6 Qh4 18. Bg7 Rhg8 19. Rae1 Rxg7 20. Rxe4 Qg5 21. Ra4+ Kb6 22. Rf6+ c6 23. Nd5+ Kb5 24. Nc3+ ...

It looks like SF thinks 17...Ka6? is the tipping point.
+0.62 17...Kc7
+2.03 17...Ka6
depth=28.

After 27. Nxe5?, Black is totally busted.

Some quick analysis using Honey XPro with the scoring % evaluation out put

Thanks, Mike. What does the constant "+60" before each PV mean?
