Like many people at or near the top of their chosen field, Nick Mordin is plainly obsessed. Thank God he is! For this obsession has led Mordin to write books which lay it on the line about racing and betting thereon.
One of the points he makes which made me laugh is how very very poor the TV "experts" are. I recall a year or so ago Julian whatsisname --Wilson--, one of the rather Establishment TV commentators of yesteryear, solemnly plugging the horse he owned, odds-on or very short odds anyway for a major race...NOWHERE! And it still happens daily. Look at the main racing channel on satellite. Of the three usual commentators, none usually gets a hit, but, Oh! how knowledgeable they are BEFORE the race (and indeed, all-wise, AFTER it, shameless people)!
For me, the statistics-led approach he favours is not easy to adopt; neither is the observant approach of seeing which horse is, e.g. frightened, angry etc in the paddock (and Mordin does insist you SEE the horses before backing). But this is a very useful book indeed for the backer who attends the course to bet.
