Please help me sort this out. NS are experienced "A" players and EW are club-level "B" players. NS are a father and son and have played together for probably 40-50 years.
Club Game, ACBL
I was called after the bidding was over. East complained about a 'natural' 2♣ call over 1N with xxxx. NS's cc had Landy marked (and crossed out), and recently changed to natural bids over 1N. The table action told me that North had intended 2♣ as Landy.
Before I was called, I was advised that North bid 1♣ / 2♣ over 1N, and East did not accept 1♣. North made the call sufficient to 2♣. I gave my usual lecture about calling the director at the time of the infraction.
NS play an artificial strong club, so I ruled that South was barred over 2♣, so I adjusted to 2♣ -1.
South calls me after the hand and thinks that it is the responsibility of EW to call me at the time of the infraction, because had North known that South was going to be barred because of the artificial nature of 1♣, North might have bid 2♠ on AQ9x.
My questions are:
1. Are you OK with adjusting to 2♣ -1? It seems that 1♣ was a clear mechanical error, and he forgot their agreements. Barring any UI from North, would you accept that South was hedging with 2♠ that his partner forgot, but even if he didn't that spades might play OK opposite a 'real' 2♣ call.
2. Whose responsibility is it to call the director? Does anyone 'lose their rights' in this instance?
Thanks,
