No we aren't :-) When we have a fail-high report, we simply reduce the depth, and continue a regular search, as if nothing has happened. Because this regular search (which can be called verification search) goes deeper, it might find out threats beyond null-move search's horizon. In that case, you would get the correct result even if you don't do a re-search! > >Martin
