I really didn't want to post in this thread again because some people, apparently, do not listen to reason. And it appears that, no matter how much common sense is used to justify a point of view, may people still look for any excuse to rationalize their position.
With regard to Casey Martin, and his effort to use a cart in the PGA, it was ruled that the use of the cart is a "reasonable accommodation" that allowed him to compete in the sport of golf, and that walking the course is not a fundamental aspect of the game.
When wsopmcgee said:
The fundamentals are: Use of 52 card deck, hand rankings, betting action, number of players per table, etc.
he overlooked the facts that poker is not as simple as the use of 52 card deck, hand rankings, betting action, and the number of players per table. He also said "etc," which means "and other things." Other things that are fundamental aspects of poker include the ability to
calculate the possibilities of possible hands existing based on the given board at any time,
calculate pot odds in which the chance that a potential hand will be achieved compared to an amount to call a bet divided by the current pot, the ability to
calculate of the size of the pot, at any point in a given hand, while considering other factors of the game, etc.
In Casey Martin's case, he was not granted authorization to be assisted in standing during his effort to strike the golf ball. Nor was he awarded the opportunity by the court to have a "do over" in case he lost balance, due to his disability, causing him to hit a bad shot because these elements are essential to the sport of golf.
Keep in mind that, in Andy's original question, he simply said that his girlfriend "has Dyscalculia and struggles with counting" and that "she just needs help counting up the chips to equal the relevant bet." A "reasonable accommodation," which is all that the ADA affords, is the minimal assistance to "count up the chips to equal the relevant bet," which may not be a fundamental aspect of the game. If the player who needs assistance needs the dealer to add up the chips when a player calls or raises, there should be no problem in doing that.
But allowing the use of a calculator, which may be used to keep track of the size of the pot, calculate the possibilities of possible hands existing based on the given board at any time, or calculate pot odds would be assisting the competitor in some of the fundamental and essential elements to the game of poker, which cannot be done.
