Nigee, the problem is not losing a game. The problem is, I put hours of work every day, sometimes into a single game, to figure out moves years ahead. And then somebody comes and ruins it totally.
It like you are painting your apartment for days, and the moment you are finished, you upper neighbour forget the watertap open, and flushes your entire home. Or when some idiot crashes into you, meanwhile you did everything according to rules, but he is drunk, or unstable, whatever and simply kills your family member.
I take this fucking game seriously, I had only one resign, because of a phone call, I can think 2-3 hours on 1 single move, (which is needed if you want to win high pot games), and so on.
Yet, someone comes and simply destroys weeks of my work put into a game, by sacrifying himself and dragging me down with him. I just cannot stand depending on people who are threatening my life/game/apartment/whatever.
What's the point of playing if I cannot enjoy it? Nothing I guess, so I'm leaving because I cannot join a game, where I can feel safe. (Excluding those top7 games, which I have never had any problem, whatsoever at all, those guys don't do stupid things)
That's all.
