I think he means to use the SEE routine *in place* of a tree search
below
that node.  I did this in the pre chess 4.x days, in a program called
"blitz"
which did a normal non-capture search, and then used the SEE routine at
most
endpoints rather than a traditional capture search.  Was done because of
speed,
but it definitely had tactical problems with pins and overloaded
pieces...
