Subject: How many Positions must a Program Check to complete a 9 Ply Search?

Author: Terry Ripple

 A friend of mine who has a rating of USCF 2345 asked me that in order for  your
favorite chess program to do a 9 ply search, how many moves or positions are
there on the chess board that it would need to search in order to accomplish
this goal?
 I hope i`am getting my point across to what i`am trying to ask for! It just
seems that the numbers to do such a task would be in the billions for a complete
search of 9 ply!
 Plus, they talk alot about how many Nodes per second a program can do and is
there a formula to find out how many moves or positions your favorite program
can do in relation to the KN/s?

Thankyou in advance for any help in explaining this,
Best regards,
Terry
