Going to present some hands from the NABC in Orlando that just completed. This hand from the Evening Session of the 2nd day of qualifying for the North American Swiss Teams gave a chance for declarer to make one of the more interesting plays available in Bridge.
NV vs Vul Opps, you pick up AJ7 KJ983 753 K4 and open 1H in 2nd seat. It now goes 2C on your left, 4C (Splinter), Double on your right. You bid 4H which ends the auction and the opening lead is the K of Diamonds. Dummy comes down with KT42 QT54 AJ86 8. Plan the play before reading the rest.
The only way to make the hand now is to exercise a scissors coupe on the opponents. You need to win the A of Diamonds at trick 1, and play a Club towards the K at trick 2. If you do anything else, including playing a Heart, your LHO will play a second Diamond and then lead a Club to RHO to get a Diamond ruff. Playing the Club before the Diamonds are unblocked kills the entry to RHO's hand prematurely and prevents the ruff, giving you enough time to play the rest of the hand.
Here is the complete hand
