TCEC: S20 L1 finished with Ethereal and rofChade qualifying into Premier Division (aka DivP), which is currently underway. • CCC: The 'testing and showcase of engines new to CCC' mentioned in the previous report has evolved into 'testing and showcase of new engines at CCC and of the new hardware rig'.
Last week I expanded on the CCC's 'new hardware rig' in CCC Hardware Upgrade. Let's look at today's situation for both the TCEC and the CCC.
TCEC: S20 DivP finished with LCZero and Stockfish in a dead heat and an identical score, +24-4=28. That result includes +2-2=6 in their head-to-head mini-match. The following crosstable shows the final result for all eight engines.
TCEC S20 - Division P
The same engines that qualified from S20 L1 finished in the last two places, which should relegate them to S21 L1 for the next season. LCZero and Stockfish have already started duking it out in the final match, which is tied at one win each, and which is scheduled to run until the end of the month.
CCC: After a four month break for technical problems that started in CCC15, the CCC is back with 'CCC Rapid 2021: Qualifiers'. The site's 'Info' tab lists a total of six events for 'CCC Rapid 2021':-
Qualifiers; eight engines
NNUE League; eight engines
Main League; eight engines
NN vs Classic; Stockfish, Leela, three engines from 'NNUE League', five from 'Main League'
Elite Round; Engines #1 to #6 from the "NN vs Classic" event
Finals; Engines #1 and #2 in the elite round
The six events will run for about three months. Some past CCC events, like CCC6, have finished in less a month.
[For further information from the various stakeholders in the engine-to-engine events, see the tab 'TCEC/CCC Links' at the top of this page. • NB: Leela = LC0 = LCzero]
