Instead of searching lines like 1. e4 e5 2. Nf3 Nc6 with depth 4, you'll search
lines like 1. e4 NULL 2. NULL NULL 3. NULL e5 4. NULL NULL 5. Nf3 Nc6 with depth
10, but the end position is the same.  It will always take a lot longer to see
the same lines if you allow null move everywhere in the tree.
