When balancing or competing against the opponents' 2S, one thing you fear is that your side has 3 7-card fits to choose from at the 3-level -- usually not a fun choice. But sometimes the opponents let you off the hook.

At neither vul in a close sectional KO final, North opened 1C and raised partner's 1S to 2S, and East (Marty Harris) entered with a double. I guess (?) that most good players would favor this action at these colors, even though it is far from safe. I (West) bid a scrambling 2NT, preferring this to 3C in case partner is 2=4=5=2 or the like -- I also see a case for 3C, putting the ruffs in the short hand if (as here) we have a choice of 4-3 fits. Seemingly we were headed for -100 in 3D, but North came to the rescue with a 3S bid -- he had told his story sufficiently already, don't you think?
So, my lead against 3S. It seemed unlikely hearts were going anywhere, so I avoided the AK lead and tried a trump. This was a success when Marty won and found the club shift. Now it was routine to take 6 tricks for +100, and win 5 when our teammates played 2S for +110 on the HA lead. It's cute that we must avoid touching either of our AK holdings to get all our tricks, and that my trump lead allows a succesful active defense while the HA blows a tempo! My satisfaction with this is far out of proportion to the 1 extra imp it gained.
Alas, this hand was not enough, and we lost the match by 6.
