5D making 5

This hand reminds me of Belladonna's famous 6D hand (see this: http://ruffnsluff.blogspot.com/2015/01/6d-making-6-hand-played-by-belladonna.html).

Playing a casual game [lunch bridge in Google Kirkland], you are South, and end up in 5D with west preempting in spades (showing exactly 6).

The bidding: partner (North) opens 1C, East passes, you bid 1D, 2S by West, and you end up in 5D (3NT is better).

West leads the HJ.

This is what you see.

You play low from dummy and RHO plays low too, and you win the K in hand.

How will you play? [For simiplicity, assume 3-2 diamonds if you want].


You have 9 tricks (3NT would have been great!), and need two more. So a simple squeeze or a simple endplay will not work (you get back one trick). In fact, you might need to combine both!

Assuming trumps are 3-2, there are a couple of possible lines.

1) Play RHO to have QJx of clubs.

2) Play RHO to have a single club honour and 4+ clubs.

If you go for line 1), you can eliminate spades while drawing trumps, and play AK clubs and a club, setting up your 4th club. RHO is in, and now has to give you the 11 trick by playing a heart.

If you go for line 2), you can eliminate spades while drawing trumps, but have to watch for RHO's discard. If RHO discards a heart (presumably from 3-4-2-4) you can now play a heart to the Q. If RHO now returns a club honour you can setup your clubs. If RHO returns a low club, you can win in dummy and lead another heart, setting up the heart in had, and endplaying RHO again.

If RHO discards a club, you can try to endplay RHO in clubs (AK and club), forcing RHO to give you a heart trick with the Q, and an entry to dummy for the good clubs.

Line 2 seems better.

You squeeze RHO, then endplay RHO while setting up a suit and generate two tricks in the process, similar to the hand played by Belladonna.

Interestingly, if RHO had 5 hearts, the winning defense is to win the HA at trick one, and give partner a ruff!
