newsflash

This compile has clearly broken all the records in my tests. Well done, Marco Z! TESTING STOCKFISH 221214MZ 1440. games Estimated Elo Performance= 3309 Icon_biggrin

Before trumpeting that this is the new number one SF compile under my testing conditions, lets repeat this test until 1.400 games, where the score will be much more reliable, with error bars of only +/- 13.
