Player 1 bets one chip (in stud poker the betting is usually started by the best hand showing, while in hold ’em and draw the betting order remains fixed by table position relative to the dealer on all rounds; in some games the last raiser opens the betting on the following round). Player 2 folds.
You want to figure your chance of winning this hand. You need a king on the last card to have a chance, and even then you may not win. You have seen 17 cards, the 10 exposed cards shown here (including your hole card) and 7 up cards from the first round. That means there are 35 cards you haven’t seen. If 3 of them are kings, your chance of getting a king is 3/35 = 8.57 percent. With 17 chips in the pot and 1 chip to call, you need 1 chance in 18 of winning, or 5.56 percent, to justify a call.
However, you have to consider what player 2 could have had. She should have started with an ace, king, or queen in the hole. She would never have folded a pair of queens or aces against sevens betting one chip, so she probably had one of your kings. That drops your chances of pairing from 8.57 percent to 5.71 percent. That’s
