Perhaps Dave's explanation left too much room for interpretation.
When Dave said:
We are olbigated both morally and ethically to make REASONABLE efforts to accomodate those players' with special needs.
Dave stressed the word "reasonable." Having players make room for an overweight player or a player in a wheelchair would be a reasonable accommodation. In my opinion, allowing one person to use a calculator would not be reasonable because it opens the door to allow everyone to use a calculator which, in my opinion, goes against one of the fundamentals of the game - players should use their intellect as a part of the competitive process.
Dave also said:
A mirrored box to allow an individual to illuminate and magnify the cards can be outlawed if it offers an unfair advantage to the player with special needs.
In my opinion, allowing one player, and not the rest of the field, to use a calculator offers an unfair advantage to the one player.
Dave also said:
A calculator at the table would not be appropriate during the actual play of a hand any more than a computer or a private tutor.
In my opinion, Dave suggests that calculators, computers, and private tutors at the poker table are inappropriate.
And Dave said:
Accomodate, but not at the expense of the other players.
I should not need to explain what this means to anyone who speaks and understands the English language. But, after reading the responses of some of the individuals in this forum, I wonder if an explanation should be necessary. And I wonder a logical explanation would be understood.
Dave also said:
The point: Common sense reigns, you cannot make your hold'em table eight-handed just because two or more people are obese.
"Common sense." In this example, rather than reducing the number of players who should be at the table, which would not be a
reasonable accommodation to the overweight players, because it changes the fundamentals of the game, the standard number of players should adjust their seats apart from each other or slightly away from the table so that the standard number of players has enough room, which would be a
reasonable accommodation.
