In a team game against a good pair, you feel your card looks good with one deal to go. If you can avoid a big loss on the last board, you have a shot to win. With that in mind, you pick up
♠A Q 7 5 4 ♥4 3 2 ♦A 5 ♣A K J
Your balanced shape argues for a notrump bid, but your hand is too strong, so you start with 1♠. This is your auction:
West leads the ♥J, and this is what you see:
East takes his three high hearts and shifts to the ♦J, which you win in dummy with the king. What is your plan? If you call for the ♠J, East will follow with the 2.
