A very interesting logic game

A few months ago, I invented an interesting logic puzzle/math problem. This is the puzzle: Magnus and Hikaru take turns placing one stone in a row of n boxes (n is an even number) with the following conditions:

1) They can only place their stones in empty boxes.

2) The box in which they place the stone is adjacent to at least one empty box.

They keep placing stones until one of them is unable to do so (while adhering to the conditions). The person who is unable to place a stone loses. Who has a winning strategy?
