Texas Hold-em, betting after the turn had commenced, then the dealer accidentally flipped the river card before the final player acted. What is the proper procedure to remedy the situation (by rule, if possible)?
Depends on the rules in use. Two common sets are Roberts rules and Tournament Directors Association (TDA) rules.
From Roberts Rules:
- If the dealer prematurely deals any cards before the betting is complete, those cards will not play, even if a player who has not acted decides to fold.
Also Section 5 (HOLD 'EM):
- If the dealer turns the fourth card on the board before the betting round is complete, the card is taken out of play for that round, even if subsequent players elect to fold. The betting is then completed. The dealer burns and turns what would have been the fifth card in the fourth card’s place. After this round of betting, the dealer reshuffles the deck, including the card that was taken out of play, but not including the burncards or discards. The dealer then cuts the deck and turns the final card without burning a card. If the fifth card is turned up prematurely, the deck is reshuffled and dealt in the same manner. [See “Section 16 – Explanations,” discussion #2, for more information on this rule.]
From TDA Rules, Recommended Procedure 5-C
C: A premature river card is placed back into the remaining stub, and the premature river burn card is left in place as the river burn. Once action on the turn is completed, the stub is reshuffled and the river is dealt without a new burn card.
