With no one vulnerable, you pick up the following hand:aaxxand find yourself playing 2 after the following auction:

aaxxDealer: W; Vul: Nil aaxx

The opening lead is J. You have two heart losers, one diamond loser and two club losers. To make the contract you will have to avoid a trump loser.

What is your plan to make the contract? How would you tackle trumps?

You can play the king and ace, hoping trumps break 2-2.

Alternatively, you can finesse against the Q with either opponent. Ordinarily, each line would offer about a 50% chance of success.

Before committing to either line, you could “read the opponents’ cards” as such:

Q1) Who has the Q?

A1) East has it because the J lead denied the Q.

Q2) Who has the A and K?

A2) It is not clear who has them, however West doesn’t have both the A and K because he would have led one.

Therefore, East has either the A or K or both.

Q3) Who has the A and K?

A3) For the same reasons as above, East has one or both of the A and K.

Q4) What is East’s range of high-card points?

A4) The 1NT response (Standard American) promised between 6 and 9 HCP.

Conclusion: East’s high cards include the Q, only one of the A and K and only one of the A and K. Another high heart or club would give East at least 12 HCP, too many to respond 1NT and leaving West with a hand not good enough to open. Similarly, East also can’t have the Q or Q as she would then have at least 10 HCP, also too strong to respond 1NT. West must have both the Q and Q.
