Seem like Grandmasters achieve their status by cheating and/or exploiting bugs in the game. Twice in recent days, and twice in my last game, a “Grandmaster” doubled his armies by waiting to attack until his turn was about to end, which left him with an army of equal size on both the attacking and defending positions. It occurred twice within two or three turns, which soon quadrupled the size of his army to the point his army was larger than all others combined within only two or three turns. Seems like so-called “Grandmasters” get their status not by skill, but through cheating.
This guy did this 4 or 5 times in the same game and turned a hopeless situation into a good one
Attacked from Siam to India and doubled his troops
Terry Labeau 13 is the username. I've nothing against people who form alliances but this is the sort of cheating that makes me want to stop playing. I wasted an hour of my time in that game only to be cheated by a guy doubling his troops. Jae Lee also did it in the same game, I think by watching how Terry Labeau did it.
