Knights and Knaves

Most of you will know the knights and knaves of Raymond Smullyan’s logic puzzles, the notorious truth-tellers and liars (actually, ‘liar’ is not wholly adequate, but anyway). In a true classic among these puzzles, you have to determine which one of two paths to choose (one leads where you want to be, one leads to your doom). Recently, a new solution to the puzzle has been published. You can find it here.
