My favorite card combination

How do you play Q862 in dummy opposite AK73 in hand?

Imagine (perhaps a stayman auction) that your length and top honors are known.

A hint is below the fold...

Suppose you're playing:

Q862 in dummy, opposite

AKT3 in hand.

If you start with the Ace, 5, 2, 9, then what?

Against a decent RHO, the 9 is more likely to be a mandatory falsecard from J9xx (which is a priori 3 times as likely as stiff 9), so you should play the Q next.

Is there anything you can do about this?

More in a subsequent post...


  1. Very clever. That is one super generous hint though.

    And I think you have disproved your own statement about the falsecard being mandatory.

  2. This was discussed on BBO forums just a couple of weeks ago:

    Someone there suggested falsecarding 1/3 of the time was the neutral strategy. I'm interested to see if you agree.
