Subject: Has anyone tried this?

It seems that finally alpha-beta works with my new Nero 4...

Ordering the moves at first ply helps to find cutoffs early. In deeper
plys I found such improvement(?) that I divide the legal moves into two
groups: captures and non-captures. Captures are examined first because
they should much more probably produce a cutoff than non-captures. Or
what do you think?
