Depends on your luck, sad to say. There are instances that it would be a good idea to regain your loss but if you won't be lucky enough, the loss would be bigger obviously. So maybe, playinh it 'safe' would be a good idea. But it would depend on your 'feeling', some gamblers do trust that feeling whenever they are playing, it turns out to be a good idea to some and not to others. Bottomline is that, gamble an amount you can afford losing. This should be kept in mind especially if you are highly being affevted by the outcome whenever you gamble. Just enjoy the game and whatever the outcome is, do not have regrets, which would be hard to do if you are really expecting for a win, which could lead to frustrations.
