Is Knight of Swords a yes or a no?

This card leans yes. It carries forward movement, and in a straight yes/no draw most readers take it affirmatively.

The Knight of Swords is intellect at a charge: fast, articulate, direct to the point of bluntness, and entirely unwilling to slow down for nuance or for you.

He is the fastest figure in the deck and there is no visible target. The trees bend, the birds scatter, and Smith drew all four Swords court figures under moving weather. This is the only one where the wind is unmistakably being generated by the rider.

Golden Dawn made him fiery air: the storm front rather than the storm.

Yes/no readings are the most popular use of tarot and the one it is worst suited to. A seventy-eight card deck built to describe nuance is being asked for one bit of information, and most of what it knows is discarded in the process.

A more useful version of the same draw: read Knight of Swords as what shape this takes, not whether it happens. Decisive, rapid action driven by conviction. Say it directly.

Excellent for arguments that need making and problems that need attacking, and genuinely valuable in situations where hesitation is the expensive option.

As a person he is the one who will say the thing in the meeting. That is worth a great deal and it is not the same as being right, and he does not reliably distinguish between the two.

Reversed, the lean weakens or inverts. Aggression, tactlessness, rushing in without the facts. Argument as a hobby.

The last is the most recognisable: somebody for whom disagreement is recreational, who is enjoyable at a distance and exhausting to live or work with.

Also read for force that has run out of direction, where the speed has continued past the point where anybody could say what it was for.
