In your first example, each side would get 15 minutes. Every time you complete a move, 10 seconds is added to your clock. So it's theoretically possible to never run out of time - assuming you move quickly enough, you'll always have at least 10 more seconds to move.
So in your second example, each side gets 5 minutes on their clock. In this game, there is no additional seconds added because the second number is 0.
Hello,
Could someone please tell me what the different tournament notations mean, such as 15|10 and 5|0? What do the numbers mean? I think I understand blitz and lightning, but not sure about the numbers.
Thanks
