Due to the limited games between Alpha Zero and Stockfish, it's impossible to come to any statistical analysis.
But looking at individual games, Alpha Zero at times played in a way that could only be called brilliant, and much different than any known chess engine, at that time anyway.
There are 4 chess engines that I know of
1. Alpha Zero
2. Stockfish
3. LcZero
4. GNU Chess
From sources I found is that GNU Chess is weaker compared to Stockfish.
But how do these other 3 compare to stockfish? I find that Alpha Zero has beat Stockfish, but an older version of Stockfish that is.
Does Stockfish still currently reign on top of chess engines? And if not what has taken its place?
