I simply can't see the solution to this puzzle. Anyone ? White to move

I don't understand, but yeah...

Never had such a close game 0.5 seconds left

Is there a term for this type of fork?

What about it?

I’m black. Opponent and I are fairly evenly matched and we have about the same number of wins, but I’m pretty happy with this. 😊

Why this move is brilliant?

How is it possible that this user went from 1200 to 100 rating?

Bro I missed the blunder, I never expected it

My first brilliant move

Why is this Brilliant?

Forked the whole squad - lost anyway

How would this be bad for me?

What about it?

It says this wins my opponent material, when I hit show moves it shows white sacrificing the rook. I had checkmate in 2 moves. I don’t get these analysis. Most times helpful but this one is weird.
