Most brilliant moves
I've had two games with two brilliant moves but TBH none of them were actually brilliant
First one: The fastest possible brilliant (e4 e5, Nf3 f6?, Nxe5!) and then an exchange "sacrifice" (rook for a bishop) to get the king in a spot where it could be skewered and allow me to grab my opponent's other rook.
Second one: A hanging pawn. I took a hanging pawn and it was brilliant. The space was attacked by a knight that was pinned to the queen, and apparently that made it brilliant. The second brilliant was a typical Greek Gift sacrifice, only it exposed a discovered attack on my opponent's rook.
If anything, these two games are proof that this website has the dumbest standards for brilliant moves on the planet.
