That's one way to do selective search.  But you start off with 20 moves, and
use 1 second searches to eliminate 19 of them.  What if one of them wins, but
you only see this if you search for 2 seconds?  You miss this.  What if the
one that looks best after 1 second looks bad when you follow it and do the next
one second search?
