Bumping for AlphaZero, which crushes AlphaGo Zero at Go, Stockfish (even with it's opening book) at chess, and Elmo at shogi.
"In chess, AlphaZero defeated Stockfish, winning 155 games and losing 6 games out of 1,000 (Fig. 2). To verify the robustness of AlphaZero, we played additional matches that started from common human openings (Fig. 3). AlphaZero defeated Stockfish in each opening, suggesting that AlphaZero has mastered a wide spectrum of chess play. The frequency plots in Fig. 3 and the timeline in fig. S2 show that common human openings were independently discovered and played frequently by AlphaZero during self-play training. We also played a match that started from the set of opening positions used in the 2016 TCEC world championship; AlphaZero won convincingly in this match too (26) (see fig. S4). We played additional matches against the most recent development version of Stockfish (27), and a variant of Stockfish that uses a strong opening book (28). AlphaZero won all matches by a large margin (Fig. 2)."

Finally, here's a
link to a 2+2 thread on AlphaZero crushing Stockfish where it didn't have it's opening book, so many complained it was not at full strength.
Cliffs: AlphaZero rules! The most amazing thing to me is that it somehow lost 2 out of 500 games of chess while playing the white pieces...
