Grid nim: 2xN (Posted on 2019-01-16)

Two players start with a 2xN grid of squares. Each player, in turn, may take either a single square or a 2x2 block of squares. The player who takes the last square loses.

For what values of N does player 2 win?

The problem is fine.

The tactical element seems to give rise to complications however.
