Red Brilliant

When you make a horrible move in a game of Chess, but somehow it causes you to win the game, usually by some form of trap or grand oversight by your opponent.

In chess engine analysis, a "Brilliant" is a move that's not only the best move, but considered extremely hard for the human mind to find. Meanwhile a "Blunder" is a bad move that causes a severe disadvantage in the game, and is notated with the color red. Therefore, a blunder that wins you the game is often referred to as a combination of the two, a "Red Brilliant".
