Default Missing function

How many programs have this bockage detection at the moment (Junior 9?)?

It's an interesting document. But I wonder about this code in it:

int search(alpha, beta, depth) {
// blockage detection
if (beta DRAW) {
if (blockage()) {
if (alpha = DRAW)
return DRAW;
beta = DRAW;
// continue regular search
.. . .

Why only detect blocked positions if (beta DRAW)? Why not always and
maybe get a beta cutoff?
Maybe too costly.

Rookie had the static blockage theme in, I think, in 1998 in the DOCCC.
