A cool Mate-in-1 I missed in Rapid

Why would my opponent resign?

Why was this declared a stalemate? Shouldn’t I have won?

Is this what you call a royal fork?

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?

Bro I missed the blunder, I never expected it
