Hi Desi
You made the correct decision, this can only ever be treated as a "Call", as that was the first action announced by the player which then voids the "Raise" (A 2nd action)
Nick C mentions that, Quote, "I was surprised recently when I saw Jack McCleland allow a player to announce a raise, put the call into the pot, and then in a separate move , push the amount of the raise into the pot."
I was at a tournament recently where players were allowed to do this but the players still had to declare "Raise" first, Then the player put the amount of the call in, which the dealer checked and then pulled forward slightly (to seperate the call from the raise) then the player was allowed a second motion for the total raise which the dealer then also checked and confirmed the amount of the raise and new total to the table.
When I politely asked the TD why he stated "Its a House rule, we allow it because it makes it easier for players to understand the amounts in the pot and what they have to call" the key in that sentence is "House Rule"
Interestingly I find that most of the time it is the "Senior Gentleman" that do this so It could be a left over from their old days of Brag, draw, stud ect and even possibly from the old "Movies", (I'll see your $00 and raise you $0) invariably I always get the answer "oh, thats always how i've done it" but after a while they get the hang of it.
