Your gripe is completely unfounded. There are 2 or 3 games in there to which he admits that he lost. I'll find some now.
The most prominent is the game in the chater "connect-the-dots." In this chapter the feature game is one which weeramantry lost, granted on time, but still a loss.
The game in the chapter "It's never over" is one which Weeramantry drew.
Even given the lack of a presence of games Weeramantry lost, it's still an excellent book. Besides, why should he include games that he lost? Games that he won are MUCH more instructive for him to talk about because he knows EXACTLY how he won and hwat he was thinking.
