Is Knight of Swords a yes or a no?

The answer

Yes, immediately — but check that the direction is right before the speed makes it hard to change.

What argues for it

Speed favours you here. Going at it directly is the right instrument.

Reversed

Directness would serve you, though you would need to sustain it past the first push.

When it moves

Now, or nearly. Whatever this concerns is already moving faster than you may have registered.

What to do about it

Go, and go now — but glance at the target once more before you close the last distance to it.

Reversed

Slow the charge before it becomes a collision. Speed without aim is just motion.
