When an active player is dealt out or an empty seat at the table is dealt in.When more than two cards are incorrectly faced (boxed) in the deck.In the opening hand of a game, if more than two extra cards are dealt.Exposed cards on the first or second deal by the fault of the dealer, or if the dealer exposes two or more cards at any point in the deal.The following situations are considered misdeals: If play has already started and more than one player has acted on their hand, the deal stands as is and should be played through. In the case of a misdeal, the deal will be adjusted so that the correct players receive the cards that they are entitled to in the hand. One short buy-in is allowed per game, and you may only add to your stack between hands.
For no-limit games, the buy in will generally be set at 20 times the amount of the big blind. In most limit games, the buy-in is set at 10 times the high limit of the table. A buy-in is necessary to take a seat at any poker table.
