Knave's Tour (Posted on 2009-01-23) Difficulty: 3 of 5
The following is a simple set-up for the familiar Knight's Tour puzzle, in this case on a 5x5 chess board only, with the start/finish positions as indicated:

1
25

One day, being rather jealous of all the attention the Knight gets with these kind of tours, the Knave loudly proclaimed that he too could complete this same tour board. But of course, as with Liars and Knights puzzles, the Knave will alternate between Knightly moves (the standard chess move) and Liar's moves (2 squares up, down, left, or right, starting and ending on the same color).

Could the Knave complete the tour where he initially starts with a Knightly move? How about starting with a Liar's move? (There may be more than one solution.)

Well, Charlie's pretty much nailed it! There are indeed multiple solutions with either a Knight's or a Liar's start, although it is rather interesting that the former results in almost 13 times as many possible solutions as the latter...proof perhaps of that old maxim 'Liars never prosper'!
