K53

After your 1NT rebid, partner uses New Minor Forcing (if you don't know that convention, no worries).
You deny 3-card heart support and he puts you in 3NT. You get the 5 lead as shown below.
What is your plan?
Play the J. If it wins, play more clubs.
Play the J. If it wins, work on diamonds.
Play the J. If it wins, cross to your hand in diamonds and lead a heart.

East wins the first round of hearts and returns a club which you win in hand as shown below.
Now what?
Continue clubs.
Work on diamonds.
Play your 5.
Play spades.
West wins the A as everyone follows suit. Now what?
No matter what West plays, you can win (and go to dummy if needed) and play the K and give up a heart. You will make the contract.
