Here is another one that was raised over the weekend:
The newer 'know it all player' sitting down and entering the game. I would like to say right now, I have no problem and do not degrade anyone for anything they say at the table unless it is continual, rubbish and nothing more than gibberish. Other than that, bring it on, be friendly and open and play the game to the best of your ability.
Mr. Know-it-all describing play by play to his buddy that is standing or sitting in an unoccupied seat. I mean, literally describing, out loud, before and after each hand. Then the friend is questioning everything. Every single hand correct-followed by a strong affirming, 'I told you so because of'.....whatever he said before the hand. Then, if he was wrong, he would explain it away as, 'should have been, because'.....or 'wow, surprising but anything and everything happens in the is game'....or something along those lines, etc.
Just on and on, non stop before each hand, during and after.
That stuff really bothers me, sorry it does.
