Title: Refusing the finesse...
Post by: OliverC on July 20, 2017, 02:16:00 PM
You are South and have ended up in 4 !H after the following sequence:


NS Vulnerable, Dealer East

Bidding
East        South        West       North
 No           1 !H            No          1 !S
 3 !D         No(1)          No          3NT
 4 !H         All Pass

(1) We play that a bid in front of Partner here shows extra values

West leads the Queen of Diamonds, and you can see

North (Dummy)
 !S A1032
 !H 97
 !D AJ2
 !C AK102

South
 !S Q8
 !H AQJ6532
 !D 54
 !C Q3

You win the Ace of Diamonds in Dummy. How do you play the Hearts? Actually as the cards lie it doesn't really matter, but I ignored the possible (and unlikely) finesse in favour of the Ace of Hearts and then the Queen, won by West's King, East discarding a Diamond. West now leads the 6 of Spades. How do you plan the rest of this contract?

If you play low from Dummy, then you need to read a bit more about Declarer play generally and counting the hand in particular, for two very good reasons:
I took the Ace of Spades, crossed back to the Queen of Clubs and ran all of my Hearts, coming down to

 !S -
 !H -
 !D J
 !C AK10

 !S Q
 !H 2
 !D 5
 !C 3

On the last Heart Dummy can cheerfully let go of the Jack of Diamonds. If West has the King of Spades, he cannot retain  3 Clubs, and I know for a fact that East cannot possibly have 3-card Clubs, because they must have the King of Diamonds. In fact I could count that East still had 2 Diamonds left and had already discarded 2 Spades, so the only danger to my 12th trick was East having the K!S and K!D and West only having Clubs left at this point. During the run of the Hearts, West had discarded 2 small Clubs, and East had discarded none. If I had been in 6 !H rather than 4 !H , I might have considered taking the Club finesse at this point, but in 4 !H I was content to play West for the King of Spades and still made my 12 because they had the J!C and the King of Spades.

The critical thing about this hand, however, is that you don't need to risk East having the King of Spades. Grade School maths will tell you 1 Spade, 6 Hearts, 1 Diamond and 3 Clubs comes to 11 tricks. It is physically impossible for West to be void in Clubs. That would give East 14+ cards in their hand, since they're already known to have at least 6 Diamonds and 1 Heart, and a Club void with West would give them 7 Clubs. Declarer is cast iron for 11 tricks if they go up with the Ace of Spades at trick 4 and cross back to hand with the Queen of Clubs to draw the last trump.

West started with !S K976, !H K104, !D Q, !C J8754, and East with !S J54, !H 8, !D K1098763, !C 96
