Proposal: Chess
We should look at, "what is the right and sensible thing to do" instead of "will this survive separately".
Chess is radically different from other board game, definitely different from card games, there is no LUCK factor involved in chess (Unless of course your opponent makes a mistake).
It's a game where only pure intelligence is required, nothing physical.
Of course you have to think and remember and judge people etc in cards. But chess and cards is even more different than apples and oranges.
Ask yourself these questions.
How many people have heard of Garry Kasparov or Bobby Fischer?
Can you name any reigning or former card game champion?
Check the sports column in the newspaper for references to cards?
Check the sports column in the newspaper for references to chess matches?
Do you know any school which has cards in their curriculum?
Did you know that chess is taught in public schools as a part of the curriculum in 30+ countries including Russia, Iceland, Venezuela etc and some states in India.
Having said this, I personally love playing cards (Definitely played more card game rounds than chess) and usually play a local (Kerala, India) game called twenty eight, the only questions I may have on it is regarding the rules, once that is clear there is no scope for further questions. In chess we can have a mathematically insane number of board positions hence can have that many questions/analysis options.
Any more arguments in favor or against?
