Here's the first. I'm South, in 3NT and receive a heart lead:
Here's a second. I was South again and having opened light, I found myself in a tough spot after partner doubled their 3H contract. His double shows a good hand that is long in clubs, short in hearts and willing to play in a diamond contract or for me to pass it for penalty. Unfortunately, I am also short in hearts and my diamonds are quite bad. My club king, though, is promising. The 3NT contract has play if the clubs are split 3-2 and if the clubs are 3-2, their 3H is down only 1. We needed to bid our vulnerable game and so we did. But the field didn't. The clubs were 4-1 and so the poor decision won out. Ugh.
Oh well, tomorrow is another day. Regression to the mean. All that stuff. Keeps bridge interesting.
