You can see the chess piece about 14:37 into the 3rd episode when he removes his phone after projecting the hologram of his army to Qrow and Ozpin. He also looks directly at the phone when he removes it, so there is no excuse for him not knowing. The same chess piece on Cinder's screen. He's obviously aware of something, and this may be solid evidence.
