Nim games are two player strategy games where players take turns removing objects by some rules until none remain.

For this version, place N counters in a row numbered 1 to N.

A player's turn consists of taking either one counter or two counters from consecutive positions.

Whomever takes the last counter loses (this is called a misère game.)

If you were to play this game, for what values of N would you prefer go first and what should be your first move?
