The maybe-finesses keep on coming

Durwood Fincher, a comedian, wrote, "Experience is what allows us to repeat our mistakes, only with more finesse!" Bridge players sometimes repeat a mistake by taking a finesse that should have been avoided, or - much less often - by not taking a finesse that should have been attempted.

What is the case in this deal? South is in six hearts, and West leads a trump. The auction followed Standard American, with North's three-heart jumprebid showing three-card support and at least game-forcing values. When South signed off in game, North bid what he hoped his partner could make. (If you switch the spades and diamonds, giving South 4=5=2=2 distribution, what would he rebid over two clubs? Two hearts as the default, not promising a sixth heart, or two spades, a reverse but not requiring extra strength? Discuss with your partner.)

South starts with one potential loser in each side suit. He has only 10 winners: one spade, five hearts, three diamonds and one club. The best line is to establish dummy's club suit.
