I was playing a game of gin rummy when I knocked for a non-zero amount. As I laid out my cards, I noticed that I could have rearranged to cards and gone gin.
Now this isn't a question about whether or not changing my declaration of knock to gin was in the spirit of fairness, just whether or not it is allowed by the rules.
We consulted the wikipedia page on gin rummy, read the section on knocking, and found:
Once a player knocks or declares gin the round is over and scores are tallied, players cannot draw.
The purpose of this sentence could be interpreted as:
- Saying that when either knocking or declaring gin, the had is over and a declaration cannot be changed
- OR simply that the sentence is trying to point out that a draw is no longer possible at this point
- OR both (the two are not, necessarily, mutually exclusive)
The knocking section does not seem to state clearly whether or not a knock hand can be changed to gin if the knocking player realizes their mistake.
And to add spice to this question, the interpretation of the rules is especially important, because the defending player, had I only knocked, would have been able to undercut me. So it wasn't just a question of whether I was going to receive X or Y points, it was a question of whether I would win the hand or be undercut.
Not looking for opinions, as we could create our own house rule out of this scenario going forward. Looking for any kind of official reference on the matter if one exists.
