AIIDE 2021 - McRave versus Dragon

McRave recorded all 157 games versus Dragon, but Dragon recorded only 155. I was able to align the files anyway, because Dragon’s missing games were clearly due to Dragon’s 2 crashes. I manually removed the corresponding games from McRave’s records. Then there was one more fix: The game of round 97 that McRave and Dragon both recorded that they had lost. Officially, McRave had timed out and Dragon won, so I manually altered Dragon’s game record to give it the win.

Dragon doesn’t record anything but win/loss and its own strategy, so it has nothing to say about how McRave played.

Another reaction build: PoolHatch,Overpool,2HatchSpeedling was a reaction to Dragon’s worker rush, and taught Dragon not to do that.

Not much to see here; we already knew that McRave had trouble scouting Dragon. Much of what it did recognize was correct, at least. Though what McRave saw as a proxy, Dragon called “2rax mech”. The game is game 2767 from round 61 (replay file) on Heartbreak Ridge. Nothing in it resembles a proxy; it must have been a McRave bug.
