Easy

Playing IMP pairs with a good partner and average opponents, I sit East and am dealt this in first chair both vulnerable:

A863

AQ853

953 I open 1

, and the bidding accelerates quickly. South bids 2

, and partner jumps to 3

, which we play as preemptive, but vulnerable he won't have complete garbage. North continues to 4

, and I have a decision to make. This is easy; they might go down one or they might make and we are not making 4

, so I pass. South continues on to 5

, and I double to end the auction. Partner leads the

J and the dummy is a confidence builder.

Declarer plays the

K from dummy and I win the Ace, thinking about what to play to trick three. Shall I underlead my

A to partner's honor? Or shall I cash out for down one and hope for a trick from partner? I'm thinking about this when, to my horror, declarer ruffs the

Q at trick two and plays four rounds of clubs, pitches two spades, and claims eleven tricks. She had eight diamonds! Of course, I should cash the

A at trick two to ensure the set, but I wasn't thinking about the hand yet before I had already blown it. Bridge can be a chastening game.
