Subject: Using null move to adjust alpha?

Author: Stuart Cracraft

I use null move only to return the null move search
value if >= beta, otherwise fall through to everything else

But I hear that one can use the null to adjust alpha.

When I try to adjust alpha this way:

    nullmovestuff
    alpha = MAX(alpha,nullmovescore);

my results drop precipitously.

Perhaps my method is wrong or adjusting alpha has fallen
out of favor.

Comments anyone?
