Agghhh!!  Would you at least be consistent???  You claimed
in another post that they need 40^9 nodes to search 18 ply.

Here it is:

>>You really believed all that time that
>>deep blue searched 40^9 = 262144000000000 nodes ?


Now you claim 4.5^18 * e?  Which is it:
sqrt(40)^18 = 6.32^18, or 4.5^18, or... ?
