Commit ID b939788f9de55051e0dd43e5943a0cde0f2be14e
Author Guenther Demetz

Remove a superfluous subtrahend The '- 1' subtrahend was introduced for guarding against null move search at root, which would be nonsense. But this is actually already guaranteed by the !PvNode condition. This followed from the discussion in pull request 1609: https://github.com/official-stockfish/Stockfish/pull/1609 No functional change
