Bless partner, curse partner.

You are South and hold QJ9642, 2, 5, AQ872, with E/W vul.

Your LHO is the dealer and opens 1H. Partner doubles and RHO bids 4H. You bid 4S, wondering if you missed a slam.

LHO passes, and bless partner, who bids 6S.

LHO lead the DA and you see

Curse partner. Overbid again.

While you are cursing partner, LHO goes into a tank, and emerges with a low club! Now you have a chance. Bless partner?

You play the 9, covered by the T, which you win with the Q.

Now LHO likely has the HK, DQ and the CK for his opening bid. In that case you have him, but have to time the hand correctly.

You should play all the trumps, throwing a club from dummy, then play a heart to the Q, and cash the HA and DK coming down to the DJ and CJ in the dummy and CA8 in hand.

West is squeezed in the minors.
