In these confusing situations, I would like the TDA to emphasize "making your intentions clear." How difficult is it to announce the amount?
As far as a player touching any chip that they have already placed into the pot (betting area, such as blinds) this must only be allowed when raising or completing a previous bet. I.e, blinds 500 and 1000...the action returns to the SB and he removes his 500 and replaces it with a 1000.
Players must learn that by not following these simple rules, the amount they bet may not be what they intended.
My dislike for many of the raise rules begins with MathieuP75's example above. A bets 400...B raises 1000...(making it 1000 or raising 1000 more is a big difference). If the total amount of the raise is 600 more, the total amount to call is 1000, of course. If
the intent was to raise 1000 more, the total intended amount would be 1400.
I understand the TDA ruling...the total amount is 1000. I don't like that rule. It is not supported by a dictionary's definition of raise and I'm certain that it causes confusion.
Back to MatheiuP75's example when Player B leaves the 400 in the pot, the TDA ruling of 50% would force Player A to complete the min-raise to 1600. If the raise were 1000 more...then the 400 would not qualify under the 50% rule and would have to be retracted.
I see no reason why the TDA can not insist that whenever raising, the player MUST make their intentions clear.
