Take the South hand below for the First Lesson Deal on Suit Play Overview:
Nobody is vulnerable and you are the Dealer. What is your opening bid?
After you open 1, LHO Doubles and Partner bids 2NT as shown below. The grey around 2NT means "alertable/conventional."
Let's assume this is "Jordan 2NT." This is not Jacoby 2NT (which is when the opponents Pass). Jordan 2NT (used only after a double) means partner has a limit raise in spades. (In modern bridge, a jump to 3 after the double would be preemptive).
What is your next call?
West leads the Q.
Counting the potential tricks you might lose, what do you come up with?
Where you will win the first trick and what is your plan?
Win in dummy and start diamonds with the jack.
Win in dummy and start trumps.
Win in dummy and play clubs.
Win in hand and play a low diamond.
Win in hand and start trumps.
Win in dummy and start clubs.
So, will winning the first diamond in dummy and playing diamonds work?
Unless there are terrible splits, yes, but you have to lead the J from dummy at trick 2.
Unless there are terrible splits, yes, but you can lead any diamond from dummy at trick 2.
