I would call ply 1 "at the root", and I would call ply 2 "1 ply below the root". Given these definitions, null moving at the root makes no sense but I think most people try the null move one ply below the root. Why wouldn't you? I can't think of any obvious reason for it to be less valid there. I think I heard Bob say that he doesn't allow null moves near the root in certain endgames. > >Thanks >Brian > >PS One example of it helping is BT2630.03 >5r1k/p1q2pp1/1pb4p/n3R1NQ/7P/3B1P2/2P3P1/7K w - - bm e5e6
