For example, if a team is priced at 1.90, does that really mean they have a 52.6% chance of winning? Or is it more about the book trying to spread money evenly so they lock in a profit no matter the result?
The second case could be the reason because bookmakers will always want to be on the winning side and no matter the situation, they’ll do what will favor them the most for the odds to be on their side. When a match is started and the odds are being changed, it reflects the condition of the present match that warrants them to change it but pre-match changes on odds looks very suspicious to me. It could be their in-house decisions for the odds of the bettors to be in their advantage irrespective of the outcome of the match.
