brilliant moves


It's pretty rare, but also not impossible. It's just a move that the computer was not prepared for and calculated that move as a better one than the best move it could find. I don't know how rare brilliant moves are but the first and maybe only time I discovered a brilliant move through analysis was when I analyzed a Bobby Fischer game.
