Update on Two World Champions

Before I close the series on Catching Up with Engine Competitions (October 2018), there is one more event to document. Last week's post, Stockfish Wins TCEC Season 13, was left unfinished because the Chess.com event was still running. Today the site announced Stockfish Wins Computer Chess Championship Blitz:-

The highest-rated chess engine of all time added another title to its resume this week as Stockfish decisively won the Chess.com Computer Chess Championship 2 [CCC 2]: Blitz Battle. The victory comes six weeks after Stockfish won the first revamped CCC: Rapid Rumble in October.

Trailing Stockfish by a large margin, the other three engine finalists finished in the order Komodo, Leela (Lc0), Houdini. The announcement carried news about the next event:-

CCC 2: Blitz Battle will conclude with some bonus games before Chess.com begins CCC 3: Rapid Redux, an all-new championship event with the 16 top engines in the world and a time control of 30 minutes per game plus five seconds increment per move.

The PGN for all three finished stages of CCC2 is available via the same Chess.com page. With TCEC S14 already underway and CCC3 promised soon, the engine to engine competitions will carry on for the next few months.

Continuing with an older unfinished series, the overview of Carlsen's career, I went back to Carlsen's PGN 2017-18 (October 2018), and concatenated the World Champion's record for 2017-18 onto the record for his entire career. The result is available in the usual place, Magnus Carlsen's Tournament, Match, and Exhibition Record (TMER; 2000-). The PGN will be added soon.
