An interesting and subtle hand?

Leicestershire have an annual "George Taylor" sims and annually my partner and I swear "never again" because the selected hands are so vicious. This time however, one of the hands was described in the booklet as "interesting and subtle":

The bidding was in line with the book, but the play wasn't.

The book says that originally, North obediently led his K, 2 and West with 8 tricks off the top had to play four rounds of clubs to check South's discard. When S discarded the T (rather than a subtle winning spade) West (assuming S had the A) had a count and finessed the diamonds correctly.

At our table, sitting North, I "knew" that with strange hands you should sometimes do strange things (not always with success). Hence, I led the 2! Partner won, & not sure what was going on, returned the Jack. Poor East tried the Queen but my now-bare King took it and the obvious switch to partner's Ace gave us the first seven tricks.

That top was so enjoyable, we may play again next year.
