A tempo behind on defence.

Declarer in 4Spades, guessed to play off DA first, in other rooms he was going down after playing the overcaller for the DQ. After this, when in with the second round of spades, I correctly attacked clubs, but failed to perservere, perhaps thrown off by partner's discouraging club spot. However, as the sequel showed, we were a tempo behind with the long diamond providing a club parker for declarer. I needed to knock out the CK before partner got in with his trump trick.
An interesting defensive problem.

Finding a 4-4 fit is strictly for the birds.

When I eschewed a One heart bid on my ratty 4 card suit, we failed to find out 4-4 heart fit. Declaring in 3NT, I studied the HJ lead carefully. I concluded it was fromm AJTx or KJTx and that my RHO held a stiff honor. So I ducked. No stiff honor appeared, but it turned out that the HJ was stiff and could not be overtaken safely. Thus, the operation was unscuccessful but the patient survived. For a top board no less.

A cute unblock, as OTs pour in for a top

When LHO bid spades in front of partner's AKQT, pd guided the auction to 3NT rather than defend doubled. Defense never found their three club tricks, and the proper farsighted unblock enabled diamonds to come home when two diamonds were discarded by defence.

A tough bid by partner, 90%

RHO was in the hot seat after the take out double of his weak two bid was passed for penalty, he tried to scramble and partner surprised me by taking me out of my penalty double. Right he was as he scored better than the 500 we would have got.

Winning the battle but losing the war

It was Matchpoints. The field tends to play in 3NT even when not technically the best contract. Which would have made 10 tricks. My inspired bidding to the 11 trick minor contract which was unbeatable got only 35%.
