a. Likely.

b. It's also my sign that I have to stop when I've lost all but I am not blaming anyone nor the casinos. If I lose, it's only because of me.

c. Not really. I believe that kind of thing before but it has no connection when I lose and I'm not using that as a sign to stop.

d. If I a come from a deep loss and I just want to recover, breaking even and stopping at that point is a good decision.
