X-Ray Vision!! :)
To show an absolutely brilliant example of what an x-ray attack really is, here is a live game of mine from September 15th 2011, it shows a truely painful x-ray attack I executed on my opponent - on move 45, I won't name my opponent for obvious reasons, and then the game climaxes with a beautiful checkmate with 2 queens in the centre of the board, classic stuff!!
