North is dealer and he opens. The auction goes:
Was that four-card overcall wise? Did I really want a heart lead from partner?
Partner leads the Ace of hearts (promising the king):
I encourage with the 6 of hearts, but partner probably has 4 hearts and thinks declarer is void. He switches smartly to a club. Declarer plays the King and I take the Ace. Now what?
I cash the queen of hearts. Declarer follows. Now what?
It's too late now. Too happy to be able to cash a second heart, I had failed to notice the club that partner had led and the club that declarer had played. If partner has the singleton club, I need to get our side a club ruff. If partner has the doubleton, a club return gives declarer a potential diamond discard. I erred on the side of passivity and led another heart.
This was the complete hand. Partner had led the 7 of clubs. Sadly, I don't know if declarer false carded with the 9 or if he woodenly played the 6 (as I probably would have).
