to whom it may concern, when i play blitz (1min game) most of my opponents dont move for several seconds, the suddenly their time is more and mine less, why is this? most times their 'lag' icon flashes and then they get more time!!! in my eyes this is cheating!!!! because at the end of the day its a 1 minute game, and if my opponent gets more time, its not fair
