CoG 2020 - breakdown by map
These tables show, for each bot, its win rate against each opponent, broken down by map. For example, the first table is for Stardust, and shows Stardust’s win percentages by opponent and map. The tournament played 200 round robins rotating between 5 maps, so each table cell shows the result of 200/5 = 40 games between the two opponents on that map, or slightly less than 40 if some games were not counted due to problems.
See looking forward to CoG 2020 for a general discussion of the maps. As a reminder, the maps are:
- (2)Blue Storm
- (3)Alchemist
- (3)Great Barrier Reef
- (4)Andromeda
- (4)Luna the Final
| Stardust | overall | BlueSt | Alchem | GreatB | Androm | LunaTh |
|---|---|---|---|---|---|---|
| PurpleWave | 86% | 62% | 92% | 88% | 92% | 95% |
| BananaBrain | 63% | 55% | 62% | 72% | 65% | 62% |
| BetaStar | 76% | 100% | 55% | 80% | 72% | 75% |

| XIAOYI | 95% | 98% | 100% | 98% | 90% | 90% |
| McRave | 96% | 100% | 95% | 92% | 95% | 100% |
| MetaBot | 99% | 100% | 100% | 100% | 100% | 98% |
| overall | 87.61% | 87% | 86% | 89% | 87% | 88% |
Aha, details count! Stardust’s overall results look even across maps, but there are differences for the top protoss opponents. It had some trouble on Blue Storm against PurpleWave and BananaBrain, and on Alchemist versus BetaStar.
| PurpleWave | overall | BlueSt | Alchem | GreatB | Androm | LunaTh |
|---|---|---|---|---|---|---|
| Stardust | 14% | 38% | 8% | 12% | 8% | 5% |
| BananaBrain | 42% | 40% | 38% | 45% | 38% | 48% |
| BetaStar | 70% | 85% | 68% | 75% | 70% | 52% |
| Microwave | 84% | 82% | 80% | 90% | 85% | 82% |
| XIAOYI | 100% | 100% | 98% | 100% | 100% | 100% |
| McRave | 88% | 92% | 88% | 85% | 90% | 88% |
| MetaBot | 98% | 100% | 100% | 98% | 92% | 100% |
| overall | 70.82% | 77% | 68% | 72% | 69% | 68% |
Again, differences show mainly against top opponents, where PurpleWave favored Blue Storm and struggled on Luna against Stardust and BetaStar (though it liked the map against BananaBrain). Luna is a classic macro map. Maybe PurpleWave is not as skilled at the brute force just-make-more-units-and-win style.
| BananaBrain | overall | BlueSt | Alchem | GreatB | Androm | LunaTh |
|---|---|---|---|---|---|---|
| Stardust | 37% | 45% | 38% | 28% | 35% | 38% |
| PurpleWave | 58% | 60% | 62% | 55% | 62% | 52% |
| BetaStar | 67% | 82% | 68% | 60% | 62% | 62% |
| Microwave | 74% | 72% | 57% | 80% | 85% | 75% |
| XIAOYI | 98% | 100% | 95% | 100% | 98% | 95% |
| McRave | 64% | 48% | 90% | 65% | 68% | 50% |
| MetaBot | 91% | 100% | 88% | 89% | 89% | 87% |
| overall | 69.71% | 72% | 71% | 68% | 71% | 66% |
BananaBrain by contrast shows differences versus many opponents, most notably McRave where it dominated on Alchemist and suffered on Blue Storm and Luna. A big disparity like that must mean something.
| BetaStar | overall | BlueSt | Alchem | GreatB | Androm | LunaTh |
|---|---|---|---|---|---|---|
| Stardust | 24% | 0% | 45% | 20% | 28% | 25% |
| PurpleWave | 30% | 15% | 32% | 25% | 30% | 48% |
| BananaBrain | 33% | 18% | 32% | 40% | 38% | 38% |

| XIAOYI | 46% | 25% | 30% | 80% | 32% | 65% |
| McRave | 70% | 100% | 20% | 80% | 90% | 62% |
| MetaBot | 90% | 92% | 100% | 85% | 91% | 81% |
| overall | 51.73% | 49% | 41% | 56% | 57% | 56% |
A checkerboard table. The middling overall percentages are averages of big wins and big losses. BetaStar comes across as strong but brittle.
| Microwave | overall | BlueSt | Alchem | GreatB | Androm | LunaTh |
|---|---|---|---|---|---|---|
| Stardust | 4% | 5% | 0% | 5% | 5% | 2% |

| XIAOYI | 82% | 88% | 80% | 90% | 78% | 72% |
| McRave | 42% | 28% | 60% | 32% | 48% | 40% |
| MetaBot | 86% | 95% | 82% | 98% | 75% | 82% |
| overall | 40.57% | 38% | 51% | 41% | 34% | 38% |
Also with dramatic variations, especially against BetaStar. Was there map-specific preparation, and if so, why did it not work on Andromeda, which is traditionally considered a zerg-favored map? There was an incorrect announcement of maps followed by a correction, but Andromeda appears on both lists, and in any case the map announcements are dated before the submission deadline.

Upsetting XiaoYi on even one map is not bad.
