The is hand came up very early:
South led the 2♠. North took with the Ace and switched to the A♥ and J♥ which partner took with the King. She then led the K♦, South playing the 2 and North the 10 and then the 9♦and South played the 4. With no hesitation she played the Ace and the Jack dropped. Equally as quickly she then played the Q♦and then the 5 to her 7. Next she played the 8♠ South rose with the King , returned a heart and then North took his remaining 5 heart tricks and thus the contract was off by 3.
This is a record of the chat:
….: syp

W->: 9 is good easy
….: not when they get in
W: !ds 2-2
….: yes but how did i get back to your low one
W->: 5 top !ds they are NOT blocked +3!cs + 1!!h
….: there is not please look my higher ones
….: lets just agree to disagree
….: I'm a nice person
What shocks me is that she evidently could not see how to make her contract even in the post mortem. Even an intermediate who might not look at the spots in the play, I would expect to see immediately after how the contract could be made.
Rant over.
Interestingly, a few other declarers played their K♦ first and when North dropped the Jack then proceeded to take the losing finesse into North's 10.
AFAIR, Victor Mollo's Walrus experienced no problems with hands like this. After defenders followed to a top ♦, he announced "I won't waste your time, Gentlemen", and claimed
