Dont bookies correct odds during live events? If someone was an underdog before the sport event its understandable why odds are high. If during game/fight that underdog performs not worse than a favourite, bookies wont keep same odds. For example if odds on Canada in football were +30.00 for draw against Brazil, but during game, its still 0:0 and there are 10min left to play, odds on Canada wont be same +30.00. It will be around, maybe 3.00, but that is not something impossible in my understanding.
They do adjust it from time to time, but i'm referring to those odds or sides that shift the other way (from 1.90 in prelive to 10.00 or higher). The live odds can sometimes overreact to moments where the favorite builds up their largest lead, and then the correction kicks in if the underdog manages to hold on for the next few minutes.
The best way to take risks on such games is risking small money like OP did and this doesn't mean it will keep happening, that's why they have biggest odds over others.
True, and it's why some bookies would focus the juice on the favorites.
