South's 2N in this 2/1 Game Forcing System promised better than a pedestrian 14 points, balanced.
North asked for keycards, spades assumed trump, and missing a keycard, North offered up 6 limited by choice not to bid a forcing 3.
South spurned the 8 card spade suit gambling for a key 10 point key at matchpoint premium and tried 6N.
On a heart lead, dummy's winning the T established 4 hearts, 3 diamonds, 4 clubs and 1 spade, dismissing reliance on at least one of two spade finesses.
