The queen sac is famous, but the real answer is piece coordination. White's king gets dragged into a position where every black piece hits something.
Can someone explain the compensation before the queen sac?
This was posted like a 'find the best move' thread and the replies keep saying Black's activity matters more than the queen. What exactly is White supposed to be afraid of?

Notes
Written in the tone of a /r/chess puzzle thread where people want the concrete point behind a famous combination, not just the headline move. This seeded post is framed as a public discussion board, not as the demo user's own game. The position itself comes from the exact historical PGN of Donald Byrne vs Robert James Fischer, Rosenwald Trophy (1956), sourced from scripts/data/ghost-games-seed.json and linked there via chessgames.com.

If Black hesitates, the whole thing evaporates. The reason the combination works is that every follow-up move gains time.
This is the classic activity-over-material lesson people always mention, but the position finally makes it concrete.
The long diagonals and the e-file do most of the work. Once you see that, the sacrifice stops looking mystical.
It is a great thread board because the move is flashy but the explanation is still teachable.
