Multiplayer Cribbage

In this 2-player game, a deck of standard playing cards will be used. At the start of each round, the dealer will deal 6 cards to each player, and each player needs to discard 2 cards to the crib. A card from the remaining stock will then be dealt and displayed at the bottom right corner of the screen, and this card is the "starter". If the starter is a J, the dealer will be awarded 2 points. Cards in the crib and the starter will be reserved for later use.When the round begins, the player who is not the dealer can start by playing a card from his hand. Then the dealer can also play a card from his hand and the round continues. Each card played carries a certain amount of points, A has 1 point, 2 has 2 points, and so on, while each J, Q and K carries 10 points. The current count of points will be displayed on the left of the screen. The total point from the cards played must not exceed 31. If a player cannot play any cards, he needs to say "go" and the other player can play cards from his hand until he cannot do so. If the total point is exactly 31, the player who played the last card will get 2 points, otherwise he will receive 1 point. The count is then reset to 0 and the player who did not played the last card can start to play a card. Then the round continues until both players have run out of cards. During the round, you can also score points according to the following ways: 1) when the total point is exactly 15, the player who played the card will receive 2 points; 2) when at least 3 newly played cards form a run of consecutive ranks, the player can receive points equal to the length of the run, for example, the player can get 3 points for completing a run of three; and 3) when 2, 3 or 4 newly played cards are of the same rank, the player can receive 2, 6 and 12 points respectively. When both players have run out of cards, an additional scoring phase begins. For the
