In St Louis, Fredin got a club (not spade) lead and led the ten of diamonds at trick two. Although this looked like misdirection to me initially, I think the club lead has shown that this suit is 4-1 and ducking a couple of diamonds is preparation for a squeeze, with the advantage that the defence might get over-active in a major - the fact that the lead was a club rather than a diamond is a clue that the diamonds might be 5-3.
Best defence will always beat the contract but Bilde took his king of clubs too early and permitted a second entry to dummy whilst removing his partner's heart honour. Chip Martel also made three notrump in the other semifinal, but a semi-psychic one spade opener meant that the spade lead was easily read as third from an honour and you can establish the ten of spades (at least I presume this happened as the operator lost the play).
All of which shows that this is an easier hand to play than defend. When I used this hand in a practice match it was impossible to tell that the lead is from Jxx and so the best line was unclear. Staking everything on the club finesse seems normal but destroys most squeeze chances.
