I cannot open your game under 1.84. Are you sure it has not been modded?

Use Warp Openers to bypass his bases, unless he is already fully protected against these devices; you are in deep trouble if it is so, as he probably has a Maginot line on that only entry point then.

I cannot give you any specific advice on how to deal with these bases without knowing their designs, but still... Ideas include:
- Wormholes beams, which can be used against bigger hulls, unlike Repulser Beams.
- Swarming them with a bunch of useless escorts going in close quarters. Works best if he has few bases and/or long-reloading weapons.
- If you are either very wealthy or face a small opposition, building enough missile launchers could work out. A base will only have so many PDC, and you only need to bring more seekers to start damaging the base (a seeking speed of six would be required though).
- Trying to sneak your way through. Launching a full decoy force and a few Star Destroyers could allow the Star Destroyers to survive the engagement, and then to make their run towards the system star(s). Blow up a star, and the whole system is destroyed. However, if you cannot create your own wormholes because he is protected against these, he will likely not be affected by Star Destroyers.
- The over-confident syndrom: does he have ten wormholes in all his systems? If not, find an uninhabited system in his Empire with fewer than ten wormholes, and open a wormhole leading to there. You will bypass the bulk of his defences, and should start glassing all his planets as fast as possible. If you could take down thirty of his planets or so in a single turn, you would bring down his whole Empire at once due to rioting.

So I would strongly recommand to avoid fighting the bases, unless there is really no way to outmanoeuver him (which would require him to have a perfect defensive pattern). Good luck to you if it is the latter, as you will probably need it.
