The thought of this term ever being used within the context of sports betting, and even poker, makes me cringe. Why do people refer to these losses as "bad beats"? The explanation is very simple. People inherently need to justify why something has happened when they they have no logical reason to validate the circumstances that occurred. This is especially so if the situation did not work in their favor. The fact is, there is no such thing as a "bad beat" as it pertains to betting on sports, or in poker.
For example, a bettor wagers on the UNDER, let's say the total is set at 6.5, in an MLB game. The game is scoreless through 9 innings of play, and both teams generate some offense in the top and bottom of the 12th frame. The final score ends 4 - 3. Is this a "bad beat"?
The answer to the above example, and any other is a resounding NO! Any chain of events that occurs within the allowable time parameters set for any event, game, match, or otherwise, is part & parcel. This means that the event only ends when the allowable time parameters have expired. To reference the above example once again, those 7 runs could just have easily been scored at any point in time during the game, it just so happens they were generated in the 12th inning.
The "bad beat" myth is not only a self inflicting lie, but may also contribute to an emotional imbalance that leads to "tilt".
Enjoy your evening everyone!
