Subject: Generate all moves at once of in phases

Hi friends,


In my earlier chess program i generated all the moves at once and then gave each
of them a score so that the moves were sorted something like this:

1. hash table moves
2. killers
3. cpatures on material gain
4. other moves on history


now i my program uses a different approach: first a move from the hash table is
tried, than a killer then the captures then the other moves. The difficulty here
is that a lot of time is spend checking for the legality of the hashtable and
killer moves. If i understan the Rebel page correctly, Rebel uses something like
the first mentioned approach.

Which on -or any other of course- is best?

Regards
Jan Willem
