If someone was playing slowly and made a mouse slip, I might even offer a draw. If someone is obviously playing very fast, trying to win on time, and they made a mouse slip, that's their bad luck. I wouldn't agree to a draw. That isn't the spirit of competition.
???? How in the hell could I flag him IN THE OPENING
If it's blitz, you're trying to play a bit faster. So you make a mistake with the mouse. That means that you can play incredibly fast and whenever you make a slip, just get a draw. Someone pre-moved against me the other day. It was quite funny. For some reason they pre-moved to take a piece but I moved that piece so I got a piece for nothing. If he'd asked for a draw I would have laughed instead of smiled.
I would have accepted the draw, but at the same time, nobody else caused the mouse slip…
