Scoring: IMP

In an auction best forgotten, 3 passes to west who opened 1. Partner doubled, and opponents ended up in 4, which you doubled.

Partner surprises you by leading the 9, which dummy ducks. What now?



As always, I apologize if the problem isn't as interesting/useful as I thought it was.

Still decidedly intermediate - don't take my guesses as authoritative.

I don't understsand, did West open in 1.seat or did it go pass-pass-pass-1?

The greedy defense is to play 3 rounds of spades. However, this would give away the contract if declarer has both red aces and Kx of clubs. In this case we'd have to switch to hearts before our club ace is knocked out.

Fortunately we can cash two high spades to see what signal partner plays. If partner plays a high heart or a low club (assuming standard carding) then I switch. If not then I continue with a third spade.
Please note: I am interested in boring, bog standard, 2/1.

3 passes to west, who opened 1 in 4th position.

Very good point, Han. I doubt I would have been able to visualize declarer's perfect hand at the table, though obviously dummy's long clubs are a concern.

Again, maybe this problem was too easy for this forum.

At the table, my partner (I was North) ducked the first round, with little thought. I wonder what he was thinking when declarer played:
- Ace/King of hearts
- low heart, ruffed in dummy
- king of diamonds
- low diamond to the ace in declarer's hand
- low diamond, ruffed in dummy

Defense collected a diamond, club and 2 spades for down 1. Down 3 was there for the taking, though.

Like Han's idea. Wish I could say that was intuitively obvious. Wasn't for me tho. Maybe next time. :)
