takes a card.
Magicican can know by looking of the remainer of the cards, what number (not suit) the card is.
And so on for the rest 13, 13, 13.

Does anyone knows what principle lays here
Sorry for my english.

I believe you're taking about the "Epitome" principle, developed by Harry Lorayne and Karl Fulves.

There are some great adaptions of the idea in "The Aronson Approach", by Simon Aronson. You can see it at work in "Two Minds and a Mate", and the "Oh-Pity-Me Location".

Found it on the card forum,
Gilbreath priciple
specific handling - sal's memory opener.

I believe Max Maven uses this principle in the MOCKING BIRD.

It's sal memory opener but I remember him saying on the dvd, that the spector and only riffle shuffle the deck once; cant cut it. Unless you give the deck a flase cut retaining its order/
