Quite often, especially early in a tournament, players will inadvertently toss in more than the current bet amount and then immediately pull the extra amount back.
For example, blinds are 50/100 , Player A bets 100 and Player B presumably means to call the 100 but a second 100 chip "trickles" along with the first. Player B then pulls the second chip back. By the book, the second chip would be a raise. Usually no one raises an objection.
I wonder though what should really be done here! Personally, I think it is proper for a player or dealer to speak up and note the raise. Rule 2 now talks about Player Responsibilities and one of those listed is to "speak up if they see a mistake being made"
Note that Rule 2 does not have the "in the interest of fairness" caveat that Rule 1 Floor Decisions provides.
Or maybe a floor decision might use the fairness clause to overrule the raise.
The above example is a bit benign, but could have a much bigger impact if the same inadvertent raise was made and a previous caller had limped with the intention of check-raising. Now the raise would facilitate the check raise!
Thanks for your thoughts!
