Mask

The robots from RUR were able to win, because they had a mask on, and were never showing what they were planning to their human masters. Onibaba was able to successfully scare the young lady, because she wore a mask. Mike successfully tricked Margaret, because he had an invisible mask on. Claudius too, kept his position for at least a while, until somebody blew it away to Hamlet, because of the manipulated mask that he put on. The mask really gets you to win.

Especially in 21st century, letting others know of what you think is very critical. In the field of business, if your opponents know your plan, you might even go bankrupt. If you knew how the stockmarket was going to work, and there was no mask on top of those who owned the companies, they everybody might be rich. The mask is what gets this world going around and must be worn to be a winner.
