Find the 2 Brilliant Moves.

Announcing a brilliancy without explaining it is as nonsensical as awarding a Nobel prize without telling for which scientific achievement it is. Whereas the Nobel prize is given after the achievement, it is the opposite for a brilliancy. Though it exists in the mind of the player, it is only visible to us through the game moves or the analysis following the brilliancy. It's looking forward, not backward!
So how can we see the brilliancy in the move 18. Rxf7!! ? NOT by playing the engine move 18 ..Re7 which is not aimed at explaining anything. The critical continuation is: 18. ..Kxf7 19. Rf1+ Kg8 20. Rxf8+ Rxf8 21. Qxg7# That is why white's 18th move is brilliant and that is why SF rated it as "brilliant".
