Advice on protecting unarmed ships

[Joe Cool]

I'll definately defend it (and spend heavily on Intel -- thanks, Slick!). What is unclear to me is:

(1) How can I ensure that the enemy won't go past my warships and kill it?

(2) How can I ensure that it will fire it's wormhole weapons should enemies come near?

The tactics has primary orders and secondary orders. It would seem logical to use "don't get hurt" as primary orders (to cause it to move away from enemy fleets) and "max range" as secondary ordrs (to get it to fire on ships that do wind up near it (e.g., those that get beamed away after being pummeled). But, will this work?

By the way, wormhole beams don't require that you be in a heavier ship than your opponent do they? I know repulsor beams do. How about tractor beams?
Thanks!
