Maybe a low spade is right? If declarer has x AQ10xxxx Axxx x, partner's trump switch will take away one of his ruffs.
That costs the contract if he has Axx AQxxxxxx - xx. He'll win the spade in dummy and play a heart to the queen. Then I'll have the unpleasant choice of cashing the club, which allows him a discard whilst he still has an entry to dummy, or not cashing it and being strip-squeezed. However, that gives partner eight diamonds, so it's not very likely.
It would also cost if declarer had the Ax AQxxxxxxx x x or Ax AQ10xxxx Ax xx, but these are also unlikely, for different reasons.
Small
♠ also loses when declarer has void AQxxxxx Axxx xx (as Rainer said small
♣ would defeat)
But yes small
♠ is the correct defense imo. Because even if declarer has
♠ A, this insures that pd has
♦A as long as pd did not pass twice with an 8 card suit, or a 7402 hand we will be fine. When pd has
♦A we are in much better shape than when not. I loved this hand because in first glance it seems what scares the defender is declarer holding the
♠A but in reality it is the
♦A with declarer which is dangerous. Because when combined with dummy's K and ruffing value, it gives declarer about 4 tricks.
This is what declarer had in original deal.
