  Let $X_n,...,X_1$ be i.i.d. random variables with distribution function $F$.
A statistician, knowing $F$, observes the $X$ values sequentially and is given
two chances to choose $X$'s using stopping rules. The statistician's goal is to
stop at a value of $X$ as small as possible. Let $V_n^2$ equal the expectation
of the smaller of the two values chosen by the statistician when proceeding
optimally. We obtain the asymptotic behavior of the sequence $V_n^2$ for a
large class of $F$'s belonging to the domain of attraction (for the minimum)
${\cal D}(G^\alpha)$, where $G^\alpha(x)=[1-\exp(-x^\alpha)]{\bf I}(x \ge 0)$.
The results are compared with those for the asymptotic behavior of the
classical one choice value sequence $V_n^1$, as well as with the ``prophet
value" sequence $V_n^p=E(\min\{X_n,...,X_1\})$.
