My partner and I bid this nice 6♦ contract in a Sectional Swiss earlier today. But the thing that I found interesting was the play.
The opening lead was a high club. I won the ♣A, pitching away my losing spade.
Next was the ♦A from dummy. RHO showed out.
The only danger is that one of my heart winners can be ruffed out and a trump played back, leaving me with a heart loser in addition to the heart ruff. I found a neat solution.
At trick 3 I ruffed a club to hand and played a heart towards the ♥Q. Both opps followed. Now I played another heart and DUCKED it. Even if LHO had no more hearts, he could not do anything to prevent me from ruffing my last low heart in dummy and pulling trump to insure 12 tricks.
The safety play would have been even more impressive if hearts were 5-1 or 6-0. But hearts were 4-2. Still, we won 10 IMPs on the board against the 5♦ contract reached at the other table. And the IMP that I lost for not making 13 tricks did not cost a VP.
