This is a recent hand on BBO where I let my instincts takeover. I made the common mistake of failing to think at trick one, and I went down in a cold contract. Opening lead is the five of hearts. What do you think I should have done?
Put yourself in my shoes and decide. Then scroll down to make sure you got it right.
I managed to go down because I overlooked the almost certain location of the king of hearts. I should win the ace of hearts at trick one, club to the ace, ruff a club, and lead the queen of hearts. If RHO ducks I pitch my last club and likely make 11 tricks. If RHO plays the king, I ruff high and lead a top trump, losing only one club and ace of diamonds.
