The Final Four, TCEC-Style
0
4
This is not the main TCEC event, but I like the format of the TCEC Cup, a 30' + 10" knockout event that's down the final four. Very unsurprisingly, the semi-finalists are Stockfish, Lc0 (Leela), Houdini, and Komodo. The first semi is underway, featuring the first pair.
All the matches in the event are best-of-eight, with pairs of tiebreak games played if necessary. Stockfish has demolished its opponents so far while Lc0 has squeaked through its matches (scroll down the page linked above to see the brackets), but sooner or later one assumes Lc0 will devour all the conventional programs. Has that time come yet? Probably not, but we'll see.
