I recently saw a chess match being played. After a few moves, Black was to move, and the board was exactly as at the beginning, except that the white king rook (at h1) was missing. How did Black capture it -- specifically, what was the actual move?

(In reply to Goofy Gambit by Bryan)

The idea is right, but for the solution we have to consider that the black knight couldn't get to d3 or f3, for that would be check. The white knight couldn't get to d6 or f6, for the same reason.

A set of moves that satisfies the conditions of the problem would be:

1 Nf3 Nf6
2 Nd4 Ne4
3 Nf3 Ng5
4 Rg1 Ne6
5 Nd4 Nf4
6 Nf3 Nh3
7 Nd4 Ng1
8 Nf3 Nh3
9 Nd4 Nf4
10 Nf3 Ne6
11 Nd4 Ng5
12 Nf3 Ne4
13 Nd4 Nf6
14 Nf3 Ng8
15 Ng1 -
