I should have put a smiley face after my comment about betting on Special Dream.
As the stipes say, failing to take all reasonable and permissible measures is different from trying to not win the race. I don't think going 4 back the outer to 4 back the inner is seen very often on the track and is worthy of questioning. The defence of saying more favourable runners were on the pegs is a unique argument too.
I don't believe drivers try to cheat in races, it is hard enough to win at the best of times. Decision-making and competence, on the other hand, is a different kettle of fish.
