When already feeling the discomfort with the game, the long red happens .. should be able to predict the gains and detailed calculations i guess. Some people too much too long to play until finally even suffered a very severe loss. Use strong feeling and leave the games when more lost, trying at next time.
That's right, lost couple of times in a row - leave. Don't try to recover or you'll end up like most gamblers who try to recover their losses the same day - you'll lose much more than at first.
Same goes for when you win, otherwise your winning day might turn to losing day eventually.
Exactly, sometimes the signs are written plain on the wall but we are hard hearted and don't repent from playing but we go ahead until we've lost everything that we came with. So it's better to leave when you have a series of losses-about 3 or 4 losses i a row is enough for me to resign.
