I don't use the cloak mode myself. One of my opponents and I banged out 15 moves in each of two games when we saw each other online yesterday. I guess as long as they are willing to play, they will "decloak" and let you see them.

I scrutinize every game played by my opponents I am facing for the first time before I ever make a move. I look for weaknesses and try to exploit them. So, for me, cloaking might be a good thing...

...then I started thinking "hmmm...maybe they will freak out if they see me pouring over game after game..."

So, I let them observe me
