"You agreed to the time control" is a common one, but seems like a facile argument.
Both players agreed to play a chess game. If my opponent stops playing for 3 (or 30) minutes it's understandably upsetting. If my opponent thinks for 3 (or 30) minutes in a difficult position, that's understandably no problem at all.
I play alot of Live 5 minute Blitz games. Recently have noticed there are too many clock-sucking losers here. You know the ones, as soon as they start to lose they don't resign, they don't make a move, they just let the clock run down and waste my freakin time!! I call these players clock-suckers. I think this is a very fitting term and am officially laying claim to coining this Chess phrase. Please feel free to use it when you encounter a classic Clock-sucking low life. I don't have time, and I'm sure none of you do either, to sit there and watch someone suck your clock while playing chess!! Has anyone else had this happen to them?
If you agreed to play 5 min blitz, you each get 5 minutes which equals 10 min. If your opponent doesnt move, you now only have to wait 5 min or less, so you actually saved time.
Hey I'm super impressed you can add 5 + 5! wow good job! Too bad the rest of your post makes no sense. How is staring at a board for 5 minutes after your opponent has left saving time? If you can make that somehow make any sense at all I will be floored...
That pretty much sums it up...on to better things.
