Sorry, I took for granted people could not peer into the brilliance which is my mind to receive game instructions. Basically, the notation is like chess "<letter><number>", (the freezing is due to the way scanf() works, and I am too lazy to write good error checking) to place spoilers merely select an already claimed space and to remove a spoiler select a place a spoiler has been placed. To my knowledge playing as blue under difficulties 0 or -1 is unbeatable. Also, the capital letters are keepers.
