Before you make a choice, before you decide what you
can do, whether go up or down, or back, retreat losing
nothing, risking nothing, and gaining nothing either,
learn about the r e s e r v e  p a r a d o x
(unless you have already read about it while reading the
reserve rules, which is quite doubtful - people usually
don't like to read rules). It will be better, if you do.
However, it won't be worse, if you don't..... Remember,
retreating can be dangerous, too, but taking no risk at
all can be sometimes more risky than the risk itself.
