Complete Removal of handcrafted evaluation (HCE) is a pretty big milestone. Original strength of Stockfish was closer to Type B strategy (per Shannon) as opposed to Type A(brute force) of Deep Blue. That is Stockfish was evaluating relatively few positions / second compared to brute forcers (like Crafty,Fritz etc). This was offset by the best eval (basically crowdsourced human GM/IM/FM knowledge) heuretics. As an FM I could "exploit" Fritzes and Crafties from 1995-2005 by using holes in their eval. Tim Crabbe provides some examples from that era: https://timkr.home.xs4all.nl/chess2/honor.htm https://timkr.home.xs4all.nl/chess2/honor.htm With Stockfish, its eval was always top notch (compared to GM) and constantly improving. Obviously Stockfish was always a few orders faster than a human.
