In this work, we prove that in the game of FOUR FILE Chess, White has at least a Draw. FOUR FILE is a chess variant proposed by John Selfridge, in which only the `a', `c', `e', and `g' les are used. All chess rules are as usual, except that all moves must end on one of these les, and the game starts with the other four les vacant. Here, we prove that the White has at least a draw, by showing that White has a strategy to avoid a loss. We also show that Black can avoid a loss for ten out of eleven starting white moves and outline the steps to complete the proof that the game of FOUR FILE is a Draw.
