Re: On-line engine blitz tourney June

What's BelFish? Some version of SF? As an unrated engine, it went 9-0 in the lower half of the tournament. Will be interesting to see it compete next month with a saner initial score.

Re: Is this speed chess LIVE ?

Not at the time you posted, no. Note the "Published on Dec 2, 2018" text under the video, which itself is a couple days after it was actually played on Nov 30th, 2018.
