A Great Deal ...

This competition closes on Sunday 31st October 2004.

I have in my hand, face down, a pile of 13 cards, comprising one complete suit of a set of playing cards:

A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K - i.e. Ace, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King - but in a different order.

Keeping the pile of cards face-down, I take a card from the top of the pile and start to spell out the name "Ace",

A - I place the first card face-down underneath the pile,

C - I place the second card face down underneath the pile

E - I place the third card face-up on the table.

The card placed on the table is in fact the Ace.

Continuing, I then take the next card from the top of the pile and start to spell out the name "Two",

T - I place the fourth card face-down underneath the pile,

W - I place the fifth card face down underneath the pile

O - I place the sixth card face-up on the table.

This next card placed face-up on the table is in fact the Two.

I continue in this fashion - spelling out the name of each card in the correct order - and on each letter I place one card from the top of the pile to the bottom - but on the final letter of each card name I turn over the card at the top of the pile onto the table.

Each time, the card turned over is the one whose name has just been spelled out.

Eventually, I am left with one card, face-down, in my hand - & all other cards, face-up on the table - in the correct order:

A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q

The card remaining in my hand is the King.

Question

From top to bottom, in what order must the initial pile of cards be placed face-down in my hand, for this result to happen?
