What's your position regarding answering rules-related questions in the middle of a hand.
For example: Heads up on the river, Player A bets (not all in). Player B asks you "If I call A's bet, do I have the right to see his cards at showdown regardless?". Assume it's a sincere question (i.e. doesn't feel like a ruse or angle).
Do you answer:
1: Yes / No, (whatever your policy is)....
2; "you should know the rules, that's a player responsibility".
3: "we can't answer questions like that in the middle of a hand, it might affect action"
If you answer some questions but not all during the hand, what criteria do you use to decide?
