Auction starts on your left by Fred Stewart with a multi 2D showing a weak 2 in either major or some strong alternatives. Kit Woolsey on your right bids 2S, to play in spades and may have game interest in hearts, and he jumps to 4H over Fred's 2NT showing H's and better than minimum. What do you lead?
A member of the Australian OzOne squad chose a passive T of clubs in a BBO practise match against a Bramley squad, resulting in -650. I think a spade is clearcut when you think it through. What does Woolsey have if he doesn't have any game interest vs a weak 2 in spades? Spade honors? Not.
Even with a spade lead, East may go wrong. He may cash the ace of clubs, hoping for 2 spades, a club and a heart instead of shifting to a diamond (fearing that the club in dummy goes away on a diamond H). After a club lead, it was all over. No second chances.
At the other table, the contract was a heart partscore and letting the game make made a 17 imp difference. Not that it mattered that much in a practise match. Ususally hurts anyway ;)
Listen, think, lead...
