??Why on earth was this considered a brilliant move?

I'm white playing against this website's coach, and I just moved my rook from c1 to b1. I wouldn't have chosen that move, but the hint told me it was a good idea. I went to review the game, which is what this picture is, and it says it was a brilliant move. Could you help me understand why this is considered a brilliant move? It looks like the black rook on b2 can take my knight on e2 for free. The only thing I can think of is that it leaves my rook on b1 to move to b8, which puts the black king in check. That doesn't seem like enough compensation for losing a knight because the black king can very easily remove itself from check. It doesn't even seem like a good move, but it is considered brilliant. Why? Thanks for reading.

All I really could see would be the checkmate threats when you check their king, the analysis puts it at a 10 to even 20 points in advantage but I still can’t find why

- After Rb8+, Black has two king moves.

-- Kf7 loses the queen immediately (Nxf8+)

-- Ke7 also loses to Nxf8, winning the knight back and putting Black's king in a position of near certain doom.

That is sure weird about losing the queen but ur just offering a trade for rooks

Thank you for the comments, although I don't see how black loses queen after Rb8. I see the other one though.

What is weird?

White doesn't just "offer a trade for rooks", white is sacrificing a knight (temporarily).

After the opponent captures the knight, here we do Nxg7, another sacrifice, then Qxg7, then Qe6+ after that if he blocks the check with the knight or queen, we do Rb8+, which i guess is winning.

there are more variations
