cheating

[hogfan44]

Is there any way to stop two players from playing side by side, or using a cell phone to share info?  I can't prove this is happening, but I have seen partners that are either psychic, or seem to know what the other player has in their hand.  I love to play Rook, but it is not fun when it appears that your opponents may be cheating.  Is it just me that thinks this is happening?
