TCEC S17 Paused; CCC13 Underway

Let's catch up with the two most important engine vs. engine tournaments, last seen two weeks ago in my post, TCEC S17 L1 Finished; CCC13 Announced. To summarize that post,

TCEC: S17 finished the CPU qualifying stages. As for the GPU stage, there weren't enough NN engines to organize a separate league. The next scheduled event of importance was the CPU/GPU playoff for Premier Division (DivP). • CCC: The bonus events continued, with the event 'Lc0-CPU vs Komodo' just starting. The site also released plans for CCC13.

What's the current status of TCEC S17 and CCC13?

TCEC: The DivP playoff was won by Fire, ahead of KomodoMCTS. As I mentioned in the 'L1 Finished' post, 'The lack of GPU competitors appears to have left a big gap in the S17 schedule.' The site is now running a 100-game match between Stockfish and LCZeroCPU called 'S17 - This is not a SuFi Bonus', with only 1-2 games scheduled per day. Unless I'm misunderstanding something, this event will continue until the beginning of May, meaning that my next few fortnightly reports are going to be low on new TCEC content.

CCC: I looked at the format of the new season in last week's post CCC13 Shapes. The last of the three five-engine 'pools' (aka 'pentagonals'), called 'Pool B', is currently running. The first pentagonal, 'Pool C', was won by Stockfish, well ahead of Stoofvlees; the second, 'Pool A', was won by an even larger margin by Lc0 ahead of Fire. 'C-A-B', got it?

Given that CCC seems to spend more time planning its seasons than it does executing them, it's possible that CCC13 will be finished by the time I tackle the next post in two weeks.

Later: Re that last sentence in the TCEC section...

The site is now running a 100-game match between Stockfish and LCZeroCPU [...] Unless I'm misunderstanding something, this event will continue until the beginning of May, meaning that my next few fortnightly reports are going to be low on new TCEC content.

...the site issued an announcement the next day: TCEC Season 17 – Premier Division is now live! (chessdom.com). It said,

The key stages of [TCEC S17] are now live at the official website of the competition. The Premier Division kicked off with a game between the current Grand Champion Stockfish and the newcomer to the division Ethereal.

The announcement included details about the sequence of games to be played. For more about the whys and wherefores of the pause, see Speaking of TCEC, what is all this then? (talkchess.com), including a snapshot of the TCEC archive index.
