Repositioning

I actually don't see a lot of discussion or tutorial on this subject. And I think it's a rather important fundamental to grasp.

In X-Wing, ships are almost always in motion. This means that eventually two ships are going to collide. Usually this happens on about turn 2 or 3, when two squads in formation meet head-on, and then have to get past each other. But it also happens when ships are flanking. Anytime their manuvers intersect, there's likely to be a collision. 

Let's consider a T-70 X-Wing collides with a Contracted Scout.

Remember, ships move in ascending order of pilot skill. So let's say the Contracted Scout plans a 1 Forward.

Since the Contracted Scout's base will not clear Blue Ace's base, the Jumpmaster stays where it is.

If Blue Ace had planned a 4 K-Turn, he would be fine. Clearing the Contracted Scout's base, turning around, and gaining a stress.

Blue Ace could also plan a 3 T-Roll.

So far, so good. Let's replace Blue Ace with a Dagger Squadron B-Wing.

The B-Wing has a 2 K-Turn instead of a 4 K-Turn. The Scout plans another 1 forward.

And bumps. If the Dagger Squadron player had hoped that the Contracted Scout would move past, and planned a 2 K-Turn...

A collison, and a stress, even though the B-Wing couldn't complete it's manuver.

Note that even if both ships were perfectly head-on, a 2 manuver will not clear a large ship's base. Even though a large base is 2 templates long. Because the template would also have to close the space between the front/back guide "nubs". There isn't enough length on a 2 template to totally clear a large base.

If the Contracted Scout had instead planned a 2 forward-

Clear. Now the Dagger Squadron can complete his K-Turn without bumping.

So both pilot skill value and predicting your opponent's manuver are important.

Let's replace the Contracted Scout with a Tie/FO, piloted by Zeta Ace.

And throw in a few asteroids. Note that neither ship has collided yet.

With a lower pilot skill, if our Dagger Squadron player had planned a 2 K-Turn-

A collision, a failed K-Turn, and a stress for his trouble. Zeta Ace completes his 4 K-Turn that he had planned-

And is on his enemy's tail, with a stress, but a clear shot, and a position to stay on the B-Wing's tail next turn.

Let's say that the B-Wing had planned a 2 Left Turn instead.

He's clear, and no stress. Zeta Ace takes his 4 K-Turn-

The B-Wing doesn't have a shot, but he didn't have a shot before either. He's now stress free, and can very likely absorb the damage from Zeta Ace on his shields. The B-Wing is in a much better position for next turn.
