The player antics (just human nature) may unknowingly disturbed other opponent when he is thinking of the next move. For sure we know talking out loud during competition should be refrained but other minor things like holding your pen and scribbling may actually disturb others who are more sensitive towards opponent's actions. Besides, players who regularly move out of their seats (to toilet, watch other boards) will also affect others.
One thing i realised things that never improve is players discussing their game when other players are still competing. They shld try to move to other locations to discuss, keeping noise level down.
Anyway, for the earlier post, I aim to apologise to anyone, should i've also caused disturbance during the course of competition. Otherwise, for players who did not achieve good results this year, let's strive to fight well in the coming Jun 2010.
