In Correspondence Chess, access to books and databases is pretty important. Certainly in almost every CC game I play, I will utilise both Chessbase and whatever opening books I have in my library, to improve my chances of winning. Sometimes this means that the game you play may only involve a few moves of original thought before getting a decisive advantage, or, as in the case of the following game, no original thought at all.
