I don't bother much, if I play a hand bad, make a mistake, run out from patiance, as everybody do it. I can live with that. Part of the game, and I know, I am profitable on my level, so probably make less mistakes than the majority of the players. (Never would call myself good, as I am not, how most of those are not, who call themselves good. The profitable is enough.)
But I really get mad because of the unbelievable 'bad beats', even I think, they should call it somehow differently in
online poker.
Examples are almost countless, like the days long river beats and relegations against 1-3 outs, when the backdoor straight, flush series going on, especially happens both with me deep in tourneys, so most of the times it is pre-flop allin or fold, can't do anything against it, even I choose the right situation, hand, and have 80-90% preflop chance to win the hand. Especially angry, when near to an end of day, session, after 8-10 hours playing, being deep in 3-6 tourneys within 5-10 minutes it happpens on all of the tables...
And it happens more often than the probability it has. Often I make my own mistakes in these times, after 3-4 fast relegation in situation like that, usually I do something stupid on the other tables, too.
The FT 'bad luck', suck with AA, or the heads-up insanities, even when I go in double or 4 times higher stack, and the opponent is in allin/fold, and he beats my nuts, 80-85% preflop win chance hands in a row 5-6 times... It is easy to count how big chance it has, and it still happens again and again...
And I could mention plenty more, days, weeks or sometimes months long crazy runs, makes me really angry, especially when it goes through for days without a bit pause...
