The first side.
hotcoffee: The first part is clear, White plays the marked stone, and black extends, and is pressed against the side until we hit the corner. It is clear black is laddered (with just 1 liberty after each white move) as he turns the corner. White plays 'a', and black is pressed all the way up the right hand side.

The next 3 sides...
The key to the puzzle is seeing that White can turn Black back against the stones again... into a spiral. If you haven't read ahead for the rest yet, do so before scrolling down, it's very rewarding to have read that many moves ahead!

The pattern emerges... read the rest of the way!

Atari!
hotcoffee: black probably regrets not tenuki-ing after the very first white move...
