1. I didn't find it at the table, but on later consideration I think DA as Pretender suggests is clearly the best shot, trying for a simple path to 4 tricks. It does clear up a guess when partner has Jxx, but so be it. This was the winning lead at the table. Even though declarer had only 3 diamonds (6=3=3=1) and can pitch the third, your trumps are promotable when partner turns up with Jx and the HA.
2. I led the CQ, and clubs were the only losing lead. I still think maybe it was normal, but perhaps there is a good reason to make a different guess. Mojo, why is a heart so obvious?
