After I had upgraded my 18 count, I had to justify myself by making 6NT. The lead was the S9, 3, J and I won with the ace. Basically I needed something to work for me. Based on the lead, I was fairly sure my RHO had the SQJ, and if the club honors were split, I was very well placed for either a squeeze or if they were 3-3 then it would be easy. The other option was the heart finesse. The heart finesse was obviously 50%, and the club position was interesting. 3-3 clubs with the honors split makes it easy. 3-3 or 4-2 clubs with the honors with LHO makes it easy. 5-1 clubs presents squeeze options. If the clubs are split and 4-2, then I only have trouble when LHO has four, since I can pick up 2-4 clubs. Anyway, I figured this rated to be roughly 70%, and clearly a better line.
So, I played the Jack of clubs and let it ride, losing to the king. Back came a diamond, which I won in hand, and led a club to the 8. When that held, I cashed the CA pitching a heart from my hand. Next I ran the diamonds except for 1 and cashed the SK, coming down to this end position:
When I cash my last diamond, there are two possibilities:
1: LHO has the HK. On my last diamond, LHO will be squeezed in Clubs and Hearts. If they pitch a club, I have a club winner in dummy, and if they pitch a heart then I win the last 2 tricks with the HA and HT without a guess.
2: RHO has the HK. On my last diamond, LHO can safely pitch a heart. Now once again, RHO either has to bare the HK or pitch the SQ. Either way I have the rest. What if RHO bares his HK... How do I know? Well, since I know LHO has 1H and 1C remaining, if the HK doesn't show up when I lead a heart up to dummy, then I know that RHO has bared the HK. I'm not exactly sure how to classify this one... 3 suit showup squeeze maybe? Either way, it was fun and looked good for all the specs ;)
