I would love to use Alpha Zero. The article makes it sound like Komodo (which uses similar techniques to Alpha Zero) could also beat Stockfish (since Alpha Zero beat Stockfish). Stockfish still beat Komodo and all other engines according to the computer chess championship which uses equal-and-limited compute requirements.

The 5/2 blitz computer chess championship is currently live (with both Stockfish and Komodo competing): https://www.chess.com/computer-chess-championship

You can run LeelaZero, which is weaker than AlphaZero but neck and neck with Stockfish. It lost 50.5-49.5 in the recent TCEC championship [0], which sounds like it is what you are referring to. (It historically has used equal hardware, but that has been complicated by the emergence of GPU engines).

What I'd like is a shim to act as a UCI engine but actually relay moves to/from LeelaZero on a remote machine. Chessbase offer something like this, but as a paid service on a proprietary protocol.

Yea the TCEC is one. I also think the chess.com computer chess championship (CCC) is interesting (Stockfish is winning here as well). The CCC uses more advanced hardware. Both are live now and interesting to watch, I mentioned the link for CCC but the TCEC is here: https://tcec.chessdom.com/

A server-based championship would also be interesting but pretty degenerate. I guess that's why computers playing more complex real-time games is becoming the bleeding edge.

AlphaZero beat Stockfish in a carefully crafted scenario for what we know [1]. The most significant breakthrough was in PR.

This criticism refers to DeepMind's late-2017 results however. In late 2018 DeepMind have published a follow-up paper[1] in Science where they claim to have beaten Stockfish 8 under non-cherrypicked conditions, specifically the conditions under which the latter won TCEC 9 in 2016.

AFAIK there are no AlphaZero results against either the current stable SF release (Stockfish 10) or the SF development version which narrowly beat Leela at TCEC 14.
