This is just a test to see if attachments are working.
CCC Blitz Championship 2021: Semifinals Game 398 Looks like small file size attachments are working.

sarona, just to be certain the game came through here fine.
(That was interesting, it looked one or the other would win, but they both Q'd at the end.)

Re: TCEC and CCC highlights
Yes, I have been following nav's Twitch streams.
There was a very nice game in this tournament where Stockfish demolished Lc0 in a Sicilian Najdorf. Castled queenside and launched an assault on the black King.
