I don’t know whether I’m being flattered or am the subject of well-deserved sarcasm In any event, I definitely don’t know ‘the solution’. In fact I strongly expect to go down absent (a) incredible luck (J10 tight in clubs? Stiff diamond King?) or (b) an almost equally improbable lie or © what I think is my best chance, misdefence! Anyway, my line is to start by winning the heart in dummy and playing a club to the queen. If it loses, win the heart return in hand and lead a club to the king and exit a club. I get 3 club tricks with 3-3 or Jx/10x either hand or AJ/ A10 in north If the queen holds, play another club, covering whatever north plays. Assuming I have three club tricks (without which I think I have zero chance), win the presumed third heart in dummy and run the clubs, reducing to KQx void Qx void opposite x void Axxx void Now a spade towards the KQx. I’m basically playing for south to be down to AJx void Kx or Ax void Kxx void (can be KJx in diamonds) or to have the heart Jack along with the diamond K and the spade Ace, and to have failed to unblock. Alternatively north to hold the spade Ace and the top heart and Kx diamonds, but he can avoid the endplay pretty easily, as can south. So I expect to fail. Oh well, gone down before and will again. Non-expert defenders will sometimes misread the situation, so that gives me a tiny bit of hope. I don’t play diamonds early so I can’t make via 3 diamonds, assuming the suit is friendly, without two clubs or egregious error,and I can’t get my second club without first losing two tricks there, a long heart,a diamond and tge spade ace. Edit. One low percentage variation is that if the 10 or Jack appears from south on the first club, I duck coming back (assuming the queen held), getting me two club tricks for the loss of one and now I’ll switch to diamonds, hoping for 3-2 with the king onside. This will look silly if north found a smooth duck from Axxx, since playing the king would generate 4 club tricks, but the odds are in favour of AJ or A10 rather than J10, if south has a doubleton, plus few players would, in real life, find that duck (although it should be automatic for an expert defender)
