Finally, I just conceded in my game against @Solfyre after about 400 ticks.
He took the lead early in the game by blitzing through the middle of the map and taking a bunch of stars on my side. I have not been able to get them all back and so the time started working against me. I was trying to launch some attacks the last couple of turns to free myself, but I failed and had to accept my loss.
Congrats to @Solfyre. You‘re an outstanding 1v1 player and you deserve to play on the top level of LLL! Good luck against @HULK in round 3!
