CoG 2021 results first look
CoG 2021 results have been posted to their website, with the detailed results file. You can look back at my view of the prospects from June. Of the 10 entrants, one dropped out, the unknown newcomer Granite. 9 participants is one more than in 2020; in 2019 there were 27. I’ll be doing my usual analyses.

The big news is that we see the first signs of zerg resurgence in the face of protoss dominance. #3 McRave and #4 Microwave pulled in front of #5 PurpleWave and #7 BetaStar, both tough opponents. BetaStar may be a holdover, but it ran ahead of the zergs last year (and this year it narrowly upset Microwave head-to-head). With holdover #6 XiaoYi as the only terran, we did not get a read on terran progress.
#1 Stardust annihilated every opponent except #3 McRave, which scored an upset. If you’ve watched games recently, that should not be a surprise. #2 BananaBrain defeated every opponent except Stardust, but not as overwhelmingly. #3 McRave, closer to #2 BananaBrain above than to #4 Microwave below, lost only to BananaBrain and to #6 XiaoYi. Tournament replays are not released, but lately McRave has been going mutalisks in every game that I’ve seen. I take it as confirmation that McRave’s steady improvements in mutalisk control have been due to effort well spent—it truly is the most important zerg skill to master at this level of play.
The randomly-chosen maps are not clearly spelled out on the website. They were (2) Ride of Valkyries, (3) Great Barrier Reef (renamed El Niño in a later version), (3) Neo Aztec, (4) Neo Sniper Ridge, and (4) Python. As far as I can judge from the map results table, most bots performed about equally on all maps. The major exception is that #4 Microwave disliked Neo Sniper Ridge while #6 XiaoYi liked it.

McRave on :
I'm mostly happy with the results, I didn't see a weakness vs XIAOYI in local testing and it was one of my best matchups, but I have room to grow in my ZvT still.
As for the Stardust upset, I spent a significant amount of time countering 4Gate and 5GateGoon builds, with hopes to completely push that build out from bot play soon. I don't think I'm too far from that, and certain releases locally were scoring 100% winrates vs Stardust, but said release was problematic in other matchups.
I knew of my BB weakness before the tournament and actually had predicted BB as winning the entire thing. I'm certain he will continue to be the hardest bot for me to beat, mostly due to his wide array of very strong 1 base openers.

And doing 22/50 (44%) vs BetaStar aligned with my local testing... which was 40-50% win rate. BeetaStar is really tough. Last year (2020) Microwave only did 22/200 (29%) but in 2019 it did 23/40 (57.5%). I think Microwave was lucky in 2019.
