I played a couple of games where I or my opponent have lost because of time out. But our clock showed that we still have 30 seconds left at that moment. Is this a bug? Please find out the problem or explain me the reason, because it is very offensively every time.
Which type of time control did you use?
I used the simple timer: 4 minutes, 1 minutes and 30 seconds for a move (in this case time ends on the ≈12 second).
yes, this type of time control has bug. It ends at 4 seconds in 1m / move
I suggest to use byo-yomi no main time 1 periods instead
