This should also be applocable to in-play matches, and even it is beyond having good knowledge about it, for example, the match between Tottenham and West Ham United in October 18, 2020, Tottenham scored 3 goals before the first 17 minutes at the beginning of the match, and they are still playing 3 goals to nothing at the 81st minutes. People can stake Tottenham to win the game after the 3 goals in the first match, but West Ham before 82nd to ending of the game equalized and played 3-3. People that will stake such game will put high amount of money, and they just lost it. Betting at times are just luck.
