The best technique to have more and bigger winning sessions is to play more when you have the biggest advantage. So if double points last for three more hours and you are feeling great, then this is a good situation and you should definitely continue. And if double points end you should probably quit even though you have won big over the last half hour. Deciding about whether to play based on game conditions is important. Making this decision based on what has happened since you last went to bed is not.
Many people care a lot about whether they are up or down today.
I don't think today's score matters much at all. Yes, that matters a lot. If that's not positive I am doing something very wrong. So any sort of shenanigans to play more or less just because you are a little up or down on the day is useless. I recently read a money management rule that makes a lot of sense for most players.
