I do not think Cooking is easy because there are many theoretical lines and the opponent can change the book theory against cooking. The opponent can use a secret opening book in important competitions and not repeat a line it used before. Maybe the only easy way is to play a bad move in the opening like 1.h3 and plan all the game after it but if the opponent uses some random factor in the first moves it cannot help. I think it is more important to do a book your program knows how to play than to think about opponents. Uri
