50-move counter update

[hgm]

Your code is somehow hard to read at the first glance. Do you mean that?

Code: Select all

revMovesAndCastlRights +=  256; 
revMovesAndCastlRights &=  (int) ( (char) (spoiler[piece] + 64) & spoiler[victim] );

One other remark:

I did not include the increment of the move counter in my first code snippet because it is best done in another place (outside the move loop):

Code: Select all

Search(int revMovesAndCastlRights)
{
    revMovesAndCastlRights += 256;
    for(ALL_MOVES)
    {
        Make();
        Search(revMovesAndCastlRights & ( (char) (spoiler[piece]+64)) & spoiler[victim]);
        UnMake();
    }
}
