What does a live reader do that a free spread cannot?
The cards are the same cards and the meanings are public, printed in every book and laid out on this site. A person adds two things, timing and friction. She lays the spread, begins to speak, sees you go still at the three of swords, stops and asks what just happened, and the next twenty minutes go to the thing you never planned to raise. She will also refuse your framing when the framing is doing you harm, which no interface will ever do. Against that, the free spread has an advantage worth naming out loud. It has no financial interest in your fear, it does not remember you, and it cannot suggest that you come back next month for the rest of the answer.

How does a session go and what should you ask?
Expect around three quarters of an hour, in person or on video, with the cards laid where you can see them. Almost all of the quality is settled in the first two minutes, when you say what you came with. Will he come back is a question that hands your life to a deck. What am I still holding on to here is a question the same cards can be read against usefully for half an hour. Avoid asking about other people behind their backs, avoid a yes or no when the yes or no is really a decision you are avoiding, and avoid stacking five topics into one hour. Ask one open question, let the reader finish before you explain everything, and say plainly when something does not land.
