Hello My Name is . . . (Posted on 2007-03-06) Difficulty: 3 of 5
You have been invited to a poker game where each of the other players (Alex, Bert, Carl, Dave) is a knight, knave or liar. The players introduce themselves as follows:

Player 1's statements:
1. Bert is a knight.
2. I am Alex.

Player 2's statements:
1. Alex is a liar.
2. I am a knave.

Player 3's statements:
1. Carl is a knave.
2. Dave is a liar.

Player 4's statements:
1. I am Dave.
2. Bert is a knight.
3. Carl is a knave.

Determine who makes which set of statements and whether each one is a knight, knave or liar.

(In reply to Alternate Solution by George)

In the tradition of puzzles on this site, Knaves alternate truth with lies, and so never tell two truths in a row as player 4 is alleged to do in the alternate solution.

Even with this proviso, if, as in your solution, Carl is allowed to talk about himself as "Carl", there are multiple solutions (see my preceding post), so it is apparently intended that Carl would only refer to himself as "I", so as to make the solution unique.
