Subject: Question about nullmove in Crafty and Beowulf

Hi to all

In Crafty and Beowulf sources I see something similar to this in the nullmove
code:

if(depth-reduc >= PLY)
   score = -Search(-beta, -beta+1, depth-reduc);
else
   score = -Qsearch(-beta, -beta+1, depth-reduc);

In the other way I use single:

  score = -Search(-beta, -beta+1, depth-reduc);

Why that engines (and I think some other too) split the null move search?
