A game is played on a strip consisting of $N$ cells consecutively numbered from 1 to $N$.
Alice has her token on cell $A$. Borys has his token on a different cell $B$.
Players take turns, Alice moves first. The moving player must shift his or her token from its current cell $X$ to the neighboring cell on the left, cell $X-1$, or on the right, cell $X+1$. Note that it's disallowed to move the token outside the strip or to the cell with the other player's token. In one turn, the token of the moving player must be shifted exactly once.
The player who can't make a move loses, and the other player wins.
Both players want to win. Who wins if they play optimally?
