Add four positions to bench The current bench is missing a position with high 50 moves rule counter, making most 'shuffle' tests based on 50mr > N seem non-functional. This patch adds one FEN with high 50mr counter to address this issue (taken from a recent tcec game). Four new FENs: - position with high 50mr counter - tactical position with many captures, checks, extensions, fails high/low - two losses by Stockfish in the S16 bonus games against Houdini See the pull request for nice comments by @Alayan-stk-2 about each position in bench: https://github.com/official-stockfish/Stockfish/pull/2338 Bench: 4590210
