And since there is 1 second added after each move in that time control, that would impact things some.
I just played 5 min +1. I thought the other one looses because auf time lapse. But it never ended for him 20 sec - 30 sec., than 20 sec than again 30 sec... This is the second time that this occurs. Has sb. made the same experience? And why does it happen?
