IMO, the dealer is part of the action. They are the final person to act on every street. The purpose of "rapping" "tapping" the table is to acknowledge to all players, with cards and without, that the action of each betting round is complete. For reasons unbeknownst to me, I'm unaware of why in the development of dealing procedures that it became proper for the dealer to "rap" and "tap" vs a simple announcement that the betting round is complete, like dealers do in pit games (ie roulette, craps, black jack). For whatever peculiarity, poker players don't want to hear the dealer say anything. The less the better. Tournament poker is sort of leaning the opposite way however, as more and more, the dealers are being trained to announce the bets. Which, I do and do not like. I like it when dealers announce a bet that is of mixed colors and hard to identify from across the table and they are just splashed in. I do not like it, when dealers take it upon themselves to break down a stack of chips that has been pushed in.
Anyway I'm getting off topic.
As a card purest, I favor keeping the board true whenever possible. I only want to shuffle the deck as a last resort. The less opportunity for a dealer to make a mistake the better.
I recently had this situation in a live action game: Full ring game, limits do not matter in this scenario. The flop is out with a random board, 7 way action. Player 1-4 check, Player 5 skipped, Player 6-7 check, Dealer raps and taps, then burns and turns. Player 5 pipes up and says he was skipped. Action is stopped and YOU rule what?
Now according to some in here, they would rule that the dealer not being part of the action that since there has only been 2 checks behind Player 5 the dealer had burned and turned prematurely and would rule in favor of Player 5 and bring back the turn card.
According to others, they would rule that the dealer is indeed part of the action, in fact completes the action, and would rule that the card stand.
What if the dealer burned and turned and Player 1 acted on that card (Check or Bet) and that's when Player 5 spoke up. Would you make a different ruling?
Personally I'm standing behind my dealer and letting the action and the turn card stand. What is the purpose of "rapping" "tapping" if we as floor personnel are going to say to our customers that the procedure of "rapping" "tapping" is invalid anytime you're skipped? Where do you draw the line? You have to draw it somewhere so you might as well stand behind a tried and true procedure. Your customers may not like it, but they'll respect you more when you ask them, "Did my dealer "tap" the table?" and when they answer yes, you have a leg to stand on and keep the TRUE card on the board. JMO.
