If you can't stand the heat - keep away from the fire.
We play bullet or blitz 3/0 - don't bore me telling me your position was winning and you "lost only due to flagfall." (I am not the one to teach anyone the sense of the clock or the importance of time in this game).
If this does not help and you still feel like that - please do challenge me for a 3 days game (you should have at least 2.200 ELO to do so). Thanks for your kind attention.
