Your partner deals and passes, as does RHO. Now, this hand might or might not rise to your personal threshold of opening vulnerable in third position, but before you make your decision, you notice that LHO is sitting extremely still, mesmerized by whatever he has picked up. You know him well enough to know that he has a good one.
Is this a chance to cause some mischief? If so, would you deviate just a smidge (open 1D or maybe 1C), or a little more with 1M? Or is it just silly to do anything with this hand? EDIT: and would your answer be different at favorable vulnerability?
