- 1NT is 12-14 and 2♦ is a transfer to Hearts.

- The double by South has shown the values for a penalty double of 1NT (15+HCP), a takeout double (of 2♥) is best used after the transfer has been completed (this is a reasonable agreement but by no means universal).

- West is using a pass to show only a 2-card Heart suit (also reasonable because North might be forced to bid).

- North has a good defensive hand and can pass.

- East must remove the penalty double.

- The bid by South shows a 5+card suit. If South had doubled 2♥ it should be for takeout showing 3+cards in the other suits, North then has an option to pass for penalties.

- West leads K♥ and East plays the 2♥ (count signal showing odd number).

What is it reasonable to assume?

- The lead of the K♥ may be from KQ or Kx.

- Spades are 3-0 (the 1NT opening is unlikely to be 22 in the Majors).

- Hearts are 5-2.

- East has 2-4 HCP and at least one Heart honour.

- West probably has the A♣.

You have 9 top tricks, how do you play for the 10th?

There is a remote chance they give you a Club ruff and diamond discard, but the answer seems to be somehow to make the J♦ or K♣.

- West has the A♣ so you can only make the K♣ if West is end-played to lead into your K2♣.

- There are 2 possibilities to make the J♦, a successful finesse (it will lose if this is your line!) or end-play West to lead into your KJ♦ tenace.

The solution seems to be end-play West in the Minors; but how?

Problems:

- If you attempt to end-play West with Q♥ then East will have it and return a Club. West having the Q♦.

- If you attempt to cash AK♦ and end-play West with the Q♦ then East will have it and return a Club.
