TCEC S17 L2, CCC12 Rd.3 Underway

Two weeks ago,in TCEC S17, CCC12 Both Underway, I reported on the status of the top two engine-vs-engine competitions. Here's a summary of that report:-

TCEC: The 16 AB/CPU engines in the QL [Qualification League] stage are nearing the half-way point. • CCC: CCC12 is being run using a bracket format. Four engines in rd.1 compete for two slots in the 16-engine rd.2. Half of the remaining engines will be eliminated in each round. The first match 'CCC12.1' is currently underway.

Both competitions have advanced further. Following is a snapshot of their current status.

TCEC: The QL stage finished with half of the engines qualifying into the next stage, League 2 (L2). The following chart shows the full results for the eight qualifiers.

L2 is currently underway and has reached the half-way point. The top finisher in the QL stage, Defenchess, has an excellent chance of qualifying into L1, the next stage.

CCC: CCC12 rounds 1 & 2 have finished, and the last of four matches for rd.3 is currently underway. None of the matches in rds.1 & -2 was closely contested. Houdini beat Lc0-CPU convincingly in rd.2, then lost to Lc0 (-GPU) in rd.3 by nearly the same score.

A few days ago, in Stockfish 11 (forum/fishcooking), the Stockfish team announced the 'Official release version of Stockfish 11'. For an idea about its relative playing strength, see Stockfish 11 (talkchess.com).
