Hello Alexev,
Today I tried a yes/no question, but I just used my normal 3-card spread with the shadow card. The answer was obvious by the cards, and it was absolutely accurate - confirmed about one hour later.
For specific spreads, if you look in the
Tarot Spreads Forum Index and scroll down to
the fourth post you'll find a nice big list of Yes/No Spreads.
I also have read about this YES/NO spread for a full 78-card deck:
Source: Mastering the Tarot by Eden Gray
(note: this is a summary of the original from page 161)
1) Shuffle your deck WITH a mix of reversed cards
2) Cut the deck into three piles
3) Spread out each pile, and pick one card from each pile.
4) Lay out your cards: A**B**C
5) Yes is determined by upright cards, No is determined by reversed cards. If you have more of one than the other, you have your answer. All the cards upright or all the cards reversed would mean a definite YES or NO.
Make sense?
Hope that helps! As for me, I don't often ask yes/no questions, so I don't think I can give a meaningful assessment of how often they work for me.
I'm sure others will!
Bon chance,
