The computer opponent plays fair. It has no idea of the identity of cards which have not been overturned (same as you). On the other hand, the computer opponent has distinct advantages: it never forgets, and cannot be distracted.
Sometimes it may seem as though the computer has 'inside knowledge' when you see it running through an unbelievable lucky streak. Rest assured, that's all it is - a lucky streak. The computer can be beaten.
