It seems to me that if the approach should be to not ask questions, it follows that one should examine the opponents' system card at the beginning of a round. It follows from that (again, it seems to me) that the director, in controlling the movement, must allow adequate time for that examination in every round. This raises the question how much time is "adequate". Certainly the complexity of the card may affect that. How complex a card do we wish to take into account? Or do we wish to limit the complexity of the card in some way? For example, a full "two-card" system, where you might for example play 2/1 in certain vulnerabilities and/or positions and Precision in others, is a lot more complex than a bog-standard 2/1 or Acol (or whatever) card. Even some "one-card" systems may be seen as complex, if they're unfamiliar (Meckwell, Fantunes, Meckwell Lite?) So how much time do we add? Do we adjust downwards the time given for actual play of the boards? We could do that. So maybe 15 minutes a round becomes 3 minutes to examine the card + 13 minutes for the two boards, plus 1 minute "move/admin" time. That might work. Adds about half an hour to the session, though.
I'm just sort of thinking out loud here. Comments?
