[Dr Strangelove]

So using a master computer will protect a ship from Psychic subVersion, but not counter-intelligence subVersion?

If you have more intelligence points than your opponents all you have to do is make sure you put more points into your counter-intel than his points available for use against you. Any points you have left over could be used for an attack.

Suppose you have 16000 intel points, but your opponent only has 5000. If you have a counter-intel running, you can put 10000 in a ship bomb attack and still have 6000 points left to fend off an attack.
