You're up about 80 with 42 boards to go in the Bermuda Bowl final, and your opponents aren't shy to begin with, so you'll be given some defensive opportunities. Here's a chance to pad your lead...or make things a little more interesting:
You: T7 K32 QT73 AK84 Dummy: A984 T876 A J653
You deal at both vul., and it goes 1D-P-1H-1S-X-3D-X-P-P-4S-AP. I'm pretty sure 3D was a 4-card limit raise and passing 3D-X showed interest.
You lead the CA (agree?) and get the CT from partner, right-side-up. Your move?
