Near mises are common in sports betting. 1 goal is still a huge difference, there are win and loss due to 1 runs in cricket or 1 point in basketball. Surprisingly, they are not rare either. I've lost many of those bets with very small margin or a small time delay. I'm now so used to these near misses that I consider them no different from other losses. In gambling you either win or lose, margins don't matter at all, be it huge or small.
That's why I like to take cash out, I believe that their always comes up cash out offer from most bookmakers when you bet on a parlay and most of the game is already successful. The reason why some people do not accept cash out is because they are overconfident that the game will work in their favour but at the end If they loss the bet, they lost everything, both the cash out and the money they staked with. I prefer to take cash out and restake on the last few games.
Cashing out is a new feature my bookie just added and it is a life saver sometimes. I don't have exact idea how it works and seems like there's some calculations they are still trying to figure out but when you keep looking, sometimes you get your money back even when its almost sure you are going to lose the game. Still you would not be able to manage it if you wait till end for a close game.
