I primarily play live anyway (have to now due to BF), but mine are:
- Yambag who tries to run a regression analysis on every hand; even the good players who know-it-all-up at the table.
- Equally as obnoxious people who keep saying the same story or comment until they get some kind of acknolwedgement. I've found that most casual players/fish tend to try to make small talk with the people on either side of them so if I happen to be one of them, I get to hear about what they folded or "would have had" every hand. My love for their monies keeps me cordial.
- Def. people who have obviously no or very little intention of returning to the game trying to save face by saying "save my seat" and acting as if they will be back, thus preventing one of the 20 people waiting from getting said seat.
- Floors who don't keep their lists in order. Can't tell you how many times I've seen lists ruined by bad floor decisions - for example to try to open a high stakes game with the only nine guys on the list and then have it break within an hour.
Or three tables are signaling an open seat for like 20 minutes with eterna-lists and nothing gets filled.
- When a straddle-rock is in the game and the person who wins it won't play or sell it which forces the rest of us to buy another one.
- When I call someone on the river and before turning their hand over they say "You got the flush?" TABLE YOUR CARDS.
