Getting Thrashed

My one victory in the tournament shown below was erased because my opponent withdrew from the tournament. The best I could do a tie for last. After analyzing my games using a computer, I was amazed to find that each of my opponent's moves was confirmed to be the best move. The possibility of this happening by chance on each and every move is essentially zero. So it appears my opponents were using a computer. Technically, it is against the rules to use a computer. I am getting wiped out in my other tournament games as well, so I suspect the same thing is happening. I will finish out my commitments in the other tournaments, but I think I will not play any more correspondence chess. If I wanted to play against a computer, I would just play against my own computer. Click on the image to enlarge.
