I guess you assume tournament books where the chess-playing program only plays the best opening moves? Otherwise, games might be won or lost just because the opening book move was inferior. There is also a phenomena seen in a recent computer chess tournament where the programmer for one engine that lost said something like "the opponent engine simply out-searched my engine" [paraphrased]. In other words, the idea is that deeper searching provides better chess moves. For the time to come when no chess engine loses, it would be necessary that the moves found be "good enough" so that a deeper-searcher could not get a decisive advantage. The idea of "accumulation of small advantages" is relevant here. The deeper searcher may consistently find moves which are slightly better so that there is, over the whole game, an accumulation of small advantages sufficient to win.
