I've put the start of the play in and partner received a bolt from the blue when South discarded.
He asked about the second double which S said was pens and we pointed out this was alertable.
We called the director at the end of the hand saying if he thought this was even a vague possibility he doesn't cash a top spade, and this now happened:
Dir to N What was the first double - stolen bid showing spades, denied by S. What was the second double, values rather than pens (and his partner who said it was pens passed it with a void).
It was pointed out the stolen bid double would be alertable so in a self alert situation, he should have alerted it.
Director went away and decided it wasn't making anyway citing a heart loser, we suggested he looked at trick 1.
Take it from here.
(I thought W could make it anyway after cashing A♠ and pitching a club when S leads his heart winner, but N can ruff and play a trump)
3Sx-1 -200 for a decent board as NS can make 5 or 6 hearts depending on who they hook for ♦Q
