Two players start 1 meter away from a target.

They simultaneously begin moving towards the target at a same constant speed. If the left player shoots when he is X meters from the target, his shot hit with a probability [imath]1-X.[/imath] If the right player shoots when he is X meters from the target, his shot hits with a probability [imath]1- X^2[/imath].

Each player has exactly one bullet and may choose to shoot at any time during the walk. If exactly one player hit the target, that player wins. If both players shoot simultaneously and both hits , then neither player wins. Both are sent back to the starting positions and game starts over.

Similarly, if both the players miss the shots, the game starts over from the beginning.

The players don't have to shoot at the same time and they can see each other at all times. Assuming both players use optimal strategies, what is the probability that the left player wins?

Note: Though both the player uses destructive weapon and bullet in this problem, they are not criminals and violence supporter.
