Ok.

1. You will see that sometimes Natwarlal output has parenthesis in it. The PV
inside the parenthesis is the PV gotten from the Hash table. When Arena gets a
PV with a parenthesis in it, it DOES NOT ATTEMPT to translate it into another
language or another Notation. So wherever there is a parenthesis in Natwarlal
output, you will see a different Notation, the one originally used by Natwarlal.

2. When Natwarlal comes out of book, and sees that it has a bad position, it
tries to search for a longer time, so as to try to find a better move. So it may
take longer for the first move some times.
