The amount of dead money can affect the game by changed pot odds and rules of thumb. For example, there is a rule in Omaha games that anyone with a nut low hand can only raise in the final betting round if there are four players active and can just call if three players are remaining. However, if the pot size contains sizeable amount of dead money, it is allowed to raise even with three players since now the pot odds have significantly changed.

In a humorous reference to rookie players who build up the pot with their contribution but cannot hope to win it owing to inexperience and lack of skill, then the money they stake is called dead money. The player may also be called dead money and such players are found often in poker tournaments where many of them enter but have no hope or chance of making any winning and their presence only help to make the pot size grow.

The name comes from the concept that since the cards used in the game will be warm due to the players handling them and so the other card deck is cold, being not in use. Cold deck also refers to the deck of card itself or the practice of using a cold deck situation. Sometimes it I used as a verb to allude to the action of cheating or getting cheated.

In recent times, whenever in a game of poker a situation occurs that is not impossible but very rare, the hand of play is said to have been played with a cold deck. It is evident that the situations when a player has been holding a four of a kind card, where the values of the card are same and suits are different or when there is a hand of straight flush that requires five successive cards belonging to the same suit are hands that are very uncommon though not technically impossible. However, it is also definite that the straight flush is rarer than four of a kind hand. Now, if one player has a four of a kind hand and takes it for granted he is going to win the pot but ends up getting beaten by his opponent holding a straight flush, the first player may complain of a cold deck situation without explicitly accusing there has been a dishonest trick.

It has been seen that when counterfeiting happens in a poker game of Texas hold ‘em, tie hands become frequent although it is also possible someone ends up losing. A case in appoint will be when the flop cards are jack, 20 and 9 and the turn card is a queen card. Now the player with a previously advantageous hand of king and queen card will get counterfeited once the turn card is dealt and get beaten by his opponent holding an ace and a king card.

Counterfeiting is also referred to situation where hand value is changed. For example for flop cards of jack,7 and 5 anyone who had a 7 and a 5 card has two pairs and an advantage over hand holding aces. If the turn gives a jack card the first player’s hand is still strong with one of the two pairs is jack, but his opponent will beat him with a combination of ace and jack cards.

In Badugi variation of draw poker only one of the paired or triple cards of same value can be used; so a player with 4 cards can virtually end up being counterfeited and hold a 3-card or even a 2-card hand and get easily beaten.

Counterfeiting occurs most generally when a person is holding a nut low hand, which is considered to be the best possible low hand. So if one player holds a hand of an ace of spades, 3 of clubs, jack and queen of diamonds; the second player holds the ace of clubs, 2 and 9 of diamonds and jack of spades; and the third player has a hand of 9, 10, king and ace of hearts; and the flop round gives such cards as the 6, 7 and 8 of hearts, then evidently the third player has a 10-high hand of straight flush while the other two players are vying for the bottom half of the pot. It can be calculated that the second player has the nut low hand of 8, 7, 6, 2 and ace where the first player holds 8,7,6,3 and an ace. Now if in the turn round the card dealt is 2 of clubs, the two players’ hands get changed. Now the first player has the nut low of 7,6,3,2 and ace against his opponent’s 8, 7, 6, 2 and ace. Thus the turn card has improved the first player’s hand making it a nut low and the second player cannot hope to win the pot unless he gets a 3 card in river which makes it a case of counterfeiting whereby both he and his opponent will be holding 7,6,3,2 and ace and splitting the pot. Incidentally none of the two players will be holding the nut low hand which would be 6,4,3,2 and ace. If the flop cards are 8, 7 and 6 then with a hand of an ace, 2, 3 and 4, a player virtually cannot be counterfeited allowing him to play boldly.

The commonest use of declaration in a poker game is in the high/low split games whereby the player is required to verbally declare if he wants his hands to be assessed as a high or a low or both hands when showdown takes place. While this is a part of home games, the same games in casinos do not use declaration but the card speak method where the players need not make any announcement but simply reveal their cards at showdown.

It is important to remember that declaration in poker games has to be made so that other players are fully aware to its nature. While either simultaneous or in turn declaration are possible, in games where positional play is crucial, in turn declaration is not allowed a the last player to declare will then get an undue advantage. The chips in hand method comes into play in simultaneous declarations. So, all players take two chips in hand and taking them below the table transfer them to a closed hand containing one, two or no chips. When all the players bring up their closed hands up on the table, they reveal their choices, with a hand containing no chips means playing for low, one chip means playing for high and two chips mean playing for both high and low hands.
