Does the AI use creative tactics?

[Silent Sorrow]

I ask because in my current game I just had something interesting happen. I had a big fleet--my "Imperial Fleet" (heh heh) stationed on a planet just outside of my main territory. For whatever reason, the AI (the Ammonkrie) were making a big deal of it and seiging the planet.

So I parked my fleet there and waited for the excruciatingly long build-time to get up about six small weapons platforms, some facilities and some mines. The AI had as many as 50 ships arrayed against me but was not attacking--just had them surrounding me. Almost as if waiting for something. More ships, I figured.

Wrong.

I was retrofitting my ships in small batches--also an excruciatingly long process with one yard doing five components per turn. I had a feeling that it wouldn't be a good idea to set them all at the same time to retrofit. But as I kept on with it, I noticed the AI was still not attacking. So I decided to retrofit a bunch of my battle cruisers at the planet.

The very next turn the AI attacks me at the planet! Argghh!

But it gets better. I decided to resolve the battle in tactical/auto/fast mode. Imagine my surprise when it turns out the AI was attacking with mostly carriers and launched fighters at my planet. Before I realized what was happening, it was too late to get my ships to focus on the fighters, since in auto they appear to focus on the ships. And remember, my battle cruisers were out of the fight on retrofit!

The fighters actually took out my planet--all those turns and resources wasted! But after the battle the report showed that I hadn't lost a single ship. It appears the AI had specifically been gunning for the planet, knowing what effect it would have on my fleet. (Because I crushed it in ship to ship combat.)

Here's the problem now: My fleet is essentially stranded on a planet without means of repair and facing turn after turn of attacks apparently designed to whittle down my forces.

Meanwhile, I'm crash-building a massive missile fleet to come to the rescue. But will it get there in time to save the Imperial Fleet?

It was close. Real close. I tried running another colony ship in to set up a yard and begin repair again but the AI intercepted the ship and destroyed it. (Second time it got through, though.)

Has anyone else here seen devious, seemingly "creative" thinking/attacks from the AI--or was the timing of its attacks against me coincidence? (And that also brings up another question--when you are retrofitting, are your ships still visible to the enemy? If they are, how would the AI have known they were being retrofitted and thus unavailable for combat?)
