While there are no time controls. And while they have never played with time controls in their life.
Don't play without time controls.
It's useless.
If you wanna play a long game, play something like... One or two hours, no increment..
No time controls allow people to really be annoying as hell.
Some people have trouble working out what they can do, never even imagining your reply. I played against someone who took ages on each move while I took at most 20 secs per move. I asked them why and they Explained:
"I'm not like you. I'm just trying to see what I can do". They also have an annoying habit of when you recapture saying:
"Ooh, you set me up for that!" While being completely serious, which is only funny the first couple of times. The challenge is not cringing. Then they hang a knight, explaining that they are sacrificing a piece for time. While there are no time controls. And while they have never played with time controls in their life.
