I watched a video of Daniel Negreanu on youtube, I can not remember the name to search the link, in which he talked about it exactly.
In the video in question he spoke of a person who obtained good results regularly, but when he lost he ended up getting out of control and in the end, however much he had won most days, he ended up in the negative.
One justification for what happened was that when the player was able to earn a fair value in the session he was content and leave, but when he was losing, he could not identify that it was time to stop and insisted on playing try to get out of the negative, so that he did on tilt and ended up losing a lot more than he should.
The form that is said to be ideal for controlling the cash game sessions is to establish a period with which you will play, for example, if you have decided that you will play for 2 hours, after that time you should quit the game, whether it is in profit or not , and make a loss control, realized that nothing is beating, that no matter how you try, the best thing to do is take time to rest, stop playing, no use insisting and playing with tilt, countless factors may be related to the reason you're losing, either because the table only has very good players, or because it's not your day.
Another good tip is that when you start losing a lot of
hands in a row but still making a profit, you can close your session earlier to avoid getting out of your way.
