Subject: Two hash moves instead of one

Is there any sense in having two hash moves instead of one?
Since the hash move (if we have one) is the best candidate for a fail high we
put it at the first position. So, since hash moves are very good why not have
more of them?

When updating the current best move for the current ply we do:

if Score>Alpha then
   Score = Alpha
   BestMove2=BestMove1
   BestMove1=CurrentMove
end if

We should then pass BestMove1 and BestMove2 to HashStore().
I've not tested it though.

Any comments?

Best regards,
Alvaro Cardoso
