Went for a lucky play. At 125 I had 2 Angels and 21 Behemoths, was preparing to take the Dragon Fly Hive, and had no further plans after that. My opponent accidentally conceded. I did not give auto. It's a tournament game, so I believe I have the right. Thanks for the game. All games are for rating.
Damn, right-clicked on an object, the computer assumed I was conceding, and I misclicked: no hero, no troops. Of course, it's a tournament game, but fair play hasn't been canceled even in the finals.
