Sitting North, the other day at a club we had the following auction.
My double implied some hearts, some diamond tolerance, and some values, but had little agreement beyond that.
After the redouble, there was no alert, and when it went 1Sxx back to me, me looking at my 5 spades, asked what the redouble was. West replied it was serious, showing values. Taking a look at East's convention card, I found they played support doubles, but indeed did not have support redoubles marked. Still I was suspicious given the auction, and reluctantly decided to pull to 2D given our side seemed lacked the values to set 1S. After east passed, west spoke up and corrected that the xx may have been support. After which he bid 3C which went all pass.
After my partner selected a lead, I decided I should call the director in case there was damage defending somehow related to either mis-information about the XX regarding the spade break, or some sort of UI that caused E/W to escape a bad spade contract everyone was in for a top.
Now here in the explanation to the director I faced another dilemma-- what was the best way to explain the situation to the director without now giving UI to my partner? I ended up just calling the director to notate the irregularity with the missed alert regarding the unclear spade support, but I'm wondering if I should have perhaps asked to do so away from the table, or done something else, in case I was now damaging our opponents.
The redouble turned out to be support (which it seems was agreed upon-- west was just having trouble remembering and east forgot to mark it on his card). We set 3C down 1, me managing to give my partner spade ruffs (declarer played spades first with a finesse, and then when I won the lead K, making the first spade return so any UI I gave with the director call turned negligible), with the result ended up being average-minus for us, so we decided not to call the director back. Interestingly enough, 1Sxx goes down 2 on perfect defense for a top, though it seems unpractical even with the correct information to leave it in. Most pairs ended up playing 1NT E/W down 1 or 2.
So what do you think?
