Why wouldn't you want to give your opponent 15 seconds?

It is a rather courteous thing to do.

@Darksouls actually if you give them more time, you waste more of your own...

@Lysamere i got time to waste and its pretty fun to do especially when they don't resign , like this game i just played is the proper use of the +15 second rule ...

@Lysamere People are too greedy sometimes. You should always be courteous and give your opponent free time and give up your own time.

Duh.

@jij2018

Actually, some people are like "Hey, you're losing, I'll give you all the time in the world and you'll still lose!" and it's really annoying.

@mylittleb

It shows how courteous people are sometimes.

Though, it is annoying. Unless you are playing a bullet game. ;)

@mylittleb exactly! When someone does that on me it was the last game I ever played against him. This is just disrespectful considering the fact they would never do the same thing for the other side. When playing without account there is no possibility to chat or block so it usually ends in time adding battles where both have an additional hour time per move, which can be funny since it starts a new sort of game much like a staring contest xD
