A while ago I played online with a pickup partner. Long enough ago that attempt at tracing the ID would be futile, even if still in MyHands. I only ever play with pickups. During system discussion partner advised me privately that it only ever leads a major at trick1 v. NT, which may be a short suit angling for my length. I took the statement as likely hyperbole. What would it lead with C:KQJT9 and a side Ace against uncontested auction 1S-2H-2S-3H-3S-3N-P? I would also ask you for the purpose of this thread to disregard the merits of the policy. OK, whether it was being entirely literal is beside the point, I feel, which is that it had a tendency to lead a major considerably more frequently than would be expected without being prewarned (even acknowledging that perhaps that tendency is generally rife anyway). From an ethical standpoint, what are your disclosure obligations here? However moronic the policy, its success rate may be inflated by a greater appreciation of its existence by partner than by opponents from whom the policy is concealed. And that seems to me unfair and probably illegal. On the other hand, partner no doubt was trying not so much to form a partnership agreement as rather to educate me as to its perception of best bridge strategy (however warped that perception) and there is no requirement to extend bridge tutorials also to opponents. Thoughts?
