THE HIT MAN: It's all dependant on the timing. Each of you has a separate clock with your individual times. If your opponent moves 5 minutes after you do then he'll lose 5 minutes from his clock. If you take an hour to get back then you lose an hour. Hey presto he's got a 55 minute advantage.

If he makes a move just before you go offline for the night then that's a several hours advantage.

It's a good strategy to give priority to your Fischer's games and play as often as possible, even popping in for a minute at several points during the day just to check those matches. If you can arrange to get up several times during the night as well.... LOL.

You've got 500+ matches going at the moment. You might want to add your voice to the feature request that Fischer's matches be sortable to the top of the games list.
