1 It's an interesting set of games, particularly for all the interactions between Kodachi, Scorcher, Dart and Fencer. I'd say the greatest improvement would be to have @Sigero and @katastrophe swap sides occasionally. This is a good way to check whether @Sigero is learning how to beat Tank with Rover, or whether he is just learning how to beat @katastrophe. 1 It's an interesting set of games, particularly for all the interactions between Kodachi, Scorcher, Dart and Fencer.

3 I think playing the same map and matchup is completely fine. The aim of this sort of testing is often to check whether a matchup has a problem, not to somehow prove that it doesn't. A matchup has a problem if it plays poorly on any reasonably generic map, so we only need to care about one map. Sure, it is useful to know where the matchup works and where it doesn't, but for most testing a single map is fine. 3 I think playing the same map and matchup is completely fine.

5 Playing the same matchup is also fine. Some unrealistic build specialisation can appear as a result of it, but that is often not too hard to correct for in further testing. A matchup is still a problem if a specific blind rush or defense is required to avoid degenerate behaviour. 5 Playing the same matchup is also fine.

10 Rover focuses on Fencer. Tank makes few Kodachi, naked expands instead. Tank gets economy. Fencers end up outclassed by Minotaur. Kodachi still used for raids. Rover makes a lot of Scorcher and Fencer. Tank resigns. 10 Rover focuses on Fencer. Tank makes few Kodachi, naked expands instead. Tank gets economy. Fencers end up outclassed by Minotaur.

13 Early Dart corners a Kodachi but nothing occurs. Lots of maneuvering. Tank resign, probably doesn't feel like there is any way to deal with some early Fencers. 13 Early Dart corners a Kodachi but nothing occurs. Lots of maneuvering.

19 Kodachi hit by Dart+Scorcher and survives. Tank contains and naked expansions. Rover trades raiding armies and then pushes with Fencer. Econ adv for Tank. Evened up by Fencer/Dart/Scorcher. Kodachi balls trade with Rover. Lots of Dart. Kodachi has trouble vs Fencer, both around 1k. Tank makes Minotaurs and rolls mid. Loses momentum to repairing Minotaurs, but possibly could have pushed and won anyway. Twice. Nine Minotaurs chased away by six Domi, seems like the Mino could just take that. Twelve Kodachi attack six Domi. Domi live and Tank resigns. I really feel like this was Tank's game to lose. 19 Kodachi hit by Dart+Scorcher and survives. Tank contains and naked expansions.

22 Kodachi pushed against the top of the map and dies to Scorcher Dart. Tank gets contained and trades a few more Kodachi. Resigns. 22 Kodachi pushed against the top of the map and dies to Scorcher Dart. Tank gets contained and trades a few more Kodachi. Resigns.

37 My main conclusion from the games is that the matchup appears to be working so far. I think @Sigero was adapting to @katastrophe's attempts to force aggressive Kodachi play, and the aggressive play did not seem too powerful here. If it turns out that Rover can handily beat Tank while Rover is making three unit types and Tank is only making Kodachi, then perhaps this is a reasonable starting point and it is time to work on bring Blitz into the interactions. I mostly think that we don't have the breadth of data to say much more than 'seems fine so far'. 37 My main conclusion from the games is that the matchup appears to be working so far.

39 @katastrophe since you singled out Game 9 I took a closer look. What struck me is how Tank spends relatively little metal in Kodachi to tie up the Rover forces for a long time. I think Tank did pretty well to do this, but then did not use the advantage to make a better economy. Here is how the game looks at 3:00. 39 @katastrophe since you singled out Game 9 I took a closer look.

41 By 3:00 the Rover player has only seen three Kodachis, having not scouted any structures at all. Another Kodachi is about to appear in two seconds. I marked when and where the Kodachis appear on the map and played out an opening which hits those timings. My economy is a bit wobbly because I avoided using Wind and hitting the timings was a little awkward. Here is the result. 41 By 3:00 the Rover player has only seen three Kodachis, having not scouted any structures at all. Another Kodachi is about to appear in two seconds.

43 To be clear, the Rover player could not know whether they were playing against the game that happened or my expansion pattern. The radar coverage you see in the screenshot of the actual game is as far as has been scouted. To me this says that Tank could gain a lot from this type of opening. 43 To be clear, the Rover player could not know whether they were playing against the game that happened or my expansion pattern.

45 I don't know if much more can be said about @Anarchid's game. To me it looked like he gave up map control by starting in the corner, making two turrets and leaving his commander idle when it could have been pushing in. There is no point trying to catch out the Kodachi with Scorcher+Dart when there is no viable target for the Kodachi. On a map that small I would have liked to see more Ripper. 45 I don't know if much more can be said about @Anarchid's game.
