With neither side vulnerable, you hold:
East deals and opens 2. And you?
The auction continues as shown below and you get the A lead against 5. What is your plan?
Discard a low club on the A (loser on loser).
Trump, draw trump ending in dummy and play a club to the king.
Trump, draw trump ending in dummy and play a club to the 10.
Trump, strip the hand while drawing trump (trumping spades in hand and then running hearts), end in dummy to play a club and cover whatever East plays.
