Quite agree with you John, but that is the only basis upon which someone should have to show their cards, once they have surrendered the pot.
You see, I agree...but while the rule exists (and is being abused) we have two options:
1. Force all hands to be shown (which I agree is not the ideal solution)
2. Insist that the asker state the reason why he"s asking BEFORE turning the cards over. and get him to justify it.
As I said, if I choose not to show (and if called I always do) and someone wants to see my hand the conversation will go...
V. I want to see that hand
Me. "Why? Do you think I"m cheating?"
V. No, I just want to see what you had.
Me. FLOOR!
