Grand Scheme by Foxymoron

Nobody bid a grand on the following hand and there is a lot of work to do to make 13 tricks. Four pairs reached the good 6S and three of them made it. I think the unlucky declarer, Jeremy Schryber, played the right line and he failed on the actual layout:

The auction at our table was, uncontested, 1S-4C*-4D=4H-4NT-5D-6S. 4C was a splinter agreeing spades and two cue bids and RKCB led to slam. South led the queen of hearts, as West had not shown a heart suit, and had just cued hearts. Declarer won in dummy, and, very sensibly but fatally, played to ruff two clubs in dummy. He played a club to the ace, ruffed a club, played a diamond to the ace and ruffed a club. North overruffed and played a diamond and now declarer was two off as South could overtake and play another club.

In 7S, I think you have to play to set up the hearts, ruffing the second heart low and the third heart high. There is a big danger of losing a trump then, but with trumps 2-2 you will set up the hearts and can draw trumps and enjoy the hearts. In 6S, this line makes an overtrick, but it is also the only making line. After playing a club at trick two, declarer can no longer make. But this is only because the clubs are 6-2. Swap the minor suit deuces, and Jeremy would have made. Swap the black sevens instead and 7S cannot make and the only winning line now is to play three rounds of hearts, ruffing low in East, getting overruffed but still making the contract.

I think, in the grand scheme, one should choose the line that is most likely to make the contract, and that depends on whether you are in a small slam or a grand slam. The origin of "grand scheme" seems to be early 18th century about introducing social reform, although it appears in writings by Shakespearean commentators:  "Emilia refuses to stop talking and continues to reveal more information about the grand scheme to take Othello down."
