Michael (rite bid) starred with an imaginative opening lead on this hand that worked spectacularly well:

Love All, Dealer North
East opens 1 !D, West responds 3NT and all pass.

North
!S 94
!H 105
!D K832
!C 109873

What's your opening lead? There are various options here: The !C 10 (or the 9 if playing Strong 10's) or the !D 2 are the "obvious" ones. On the other hand, North has no likely entries if the !D Ace is on their left, and West's hand is clearly weighted to the Minors (no 1M bid), so looking to find Partner's long suit in a Major is a clear winner here. The !H 10 could be (and would have been) misinterpreted, and Michael chose the !S 9, which worked spectacularly well:

East (Dummy)
!S AK102
!H K643
!D Q1095
!C K

                North
                !S 94
                !H 105
                !D K832
                !C 109873

Declarer took the opening lead in Dummy with the King, South encouraging with the 5. Declarer cashed the !C King and then crossed to hand with the !H Jack. Now they led a !D towards Dummy, Michael ducked and Dummy's Queen felled South (obviously singleton) Jack. The !D 9 followed, on which South discarded the !C 6. Michael won and continued the !S attack. Declarer ducked in Dummy and Partner's 8 won the trick, Declarer contributing the !S 7. South continued with the !S Queen, West and North discarding Clubs and then the Jack when Declarer ducked in Dummy (West and North both discarding Diamonds).

When Declarer now led a Heart off the table South took their Ace and a 5th Spade for -1.

Declarer could play this hand a lot better, it's true. Clearly it's best to force out the !H Ace first, since you have no control over who wins that trick. The opening lead makes it look as if any Spade length is probably with South, and Declarer can always keep South away from the lead in Diamonds, by running the Queen and then the 10 if necessary.

This hand is actually cold for 10 tricks from the word so, even with a Spade lead. Without North's imaginative lead at trick 1, however, there is almost a zero chance of stopping this contract. That lead gave the defence a tempo, however, so that Declarer couldn't afford to make any mistakes. Conceding a Diamond to North before forcing out the !H Ace was the mistake.

Michael and I ended up in a somewhat dodgy slam today, but it was a nice sequence :) .

North (Dummy)
 !S AKQJ95
 !H J6
 !D AJ2
 !C KQ

!D 4 led

South
 !S 106
 !H A732
 !D 9763
 !C A54

Bidding (Opps silent)
North     South
1 !C        1 !S
1NT(1)    2 !H (2)
2 !S (3)    2NT(4)
3 !S (5)    4 !C (6)
4 !H (7)    5 !H ( 8 )
6 !S (9)         All Pass

(1) Beta
(2) 4 Controls
(3) Iota in Spades
(4) !S xx
(5) Repeat Iota (Sets Spades as trumps)
(6) Still !S xx :)
(7) Epsilon in Hearts
( 8 ) 1st Rnd Control of !H , no 2nd or 3rd Rnd control
(9) This pretty much needs South to have !C AJxx, since I must have !H Axx(x) and cannot have the !D King. A rush of blood to North's head, perhaps LOL.

What to do on the lead of the !D 4? It's possible that West might have led from !D KQxx, in which case the !C Jack will suffice for 12 tricks here. Much more likely, in my opinion, that the lead is from !D K10xx(x) or !D Q10xx(x), in which case East will have to play their honour in order to beat the 9. At any rate, that is what I played for and East duly won trick one with the King and switched to a Club.

I eventually took the Diamond finesse against West for my 12th trick. Nice result, but it's worth noting that for this slam to succeed, you 100% need West to lead a small Diamond from their hand at trick 1. Almost no other lead will allow you to make this. Even the !D 10 lead defeats the contract because of the finesse against the 9 on the way back.

Bidding a slam on the basis of Partner having to have cards they've not shown can be a little dodgy. Bidding a slam knowing you have multiple "holes" ( !D and !H here) is doubly so. Nice when you can enlist Opps' help to allow you to make it, though LOL.

Yes,  accidentally left out the Q !S.  Scuzzi.  The hand is now corrected.

And yes,  the way to make the 1st deal is to duck (concede) the heart opening lead,  then discard two clubs and setting up the other clubs via ruffs.

Making a plan is one of the essential igredients of Declarer play (and defence). I seem to remember saying that somewhere before :).

Coupled with that is the ability to judge what's going on on the hand and respond accordingly.

You are North, playing in 4 !S. The bidding doesn't really matter, but for the record,  You passed, Partner opened 1 !D, and the bidding went No - 1 !D - 1 !S - 2 !S - 3 !C - 4 !S

South (Dummy)
!S K954
!H Q65
!D KQJ104
!C A

!S Jack led

North
!S AQ632
!H 72
!D 8
!C KJ982

You draw trumps in 2 rounds ending in Dummy. How do you plan the play?

(1) Ruff the Clubs good. Any 4-3 Club split will accommodate this line, but you might run into problems when the Clubs are 5-2 or worse with West.
(2) Better: Force out the !D Ace and discard 3 Clubs on the winning Diamonds. This gives 10 tricks guaranteed on any distribution whatever (Just conceding 2 Hearts and the !D Ace).

At trick 3, Partner cashed Dummy's !C Ace and then led the deceptive (LOL) !D 10 from Dummy. Amazingly, both Opps ducked!!!

Now we're guaranteed 11 tricks on absolutely any distribution, and are possibly making all 13 when, as seems likely, West has the !D Ace and either the Diamonds or the Clubs are behaving. We just take the ruffing finesse in Diamonds, discarding a Heart from hand. If East wins the Ace we lose only 1 Heart and 1 Diamond. If the 2nd Diamond wins, we repeat the ruffing finesse and now we're losing no Hearts at all!

Partner had other ideas, however: She cashed the !C Ace and then ruffed a small Diamond, cashed the !C King (West played the !C 10, Dummy discarded a Heart) and ruffed a Club (West discarded a Diamond). Now another Diamond ruffed in hand (East discarded a Heart).

At this point the distribution of the hands is known beyond a shadow of a doubt, West with 2452 distribution and still holding the now singleton !D Ace, and East with 2425 distribution, and still holding !C Qx. The ruffing finesse in Clubs is now marked for 11 tricks. Partner, though, just completed her complete cross-ruff and conceded 2 red-suit tricks at the end for just 10 tricks.

The overtricks are no big deal, but on another hand you might need those tricks just to make your contract so it really pays to try to find the optimum line to make the most tricks possible safely.

Some hands really do look impossible (and some really are impossible, of course). Sometimes, all you can do is to make assumptions that the distribution is such that if offers you a chance of making, even if you're unlikely to find that exact lie of the outstanding cards.

EW Game, Dealer East

You are South:

South
 !S AK7
 !H J5
 !D KQ54
 !C K1082

Bidding
East     South     West     North
2 !S      2NT         No         3 !D
No        3 !H         All Pass

North (Dummy)
 !S 85
 !H K8732
 !D A986
 !C 74

!S 6 led

South
 !S AK7
 !H J5
 !D KQ54
 !C K1082

West leads the !S 6, Dummy goes down and East plays the !S 9. Prospects do not look promising because of the lack of intermediates in Hearts and the prospect of a poor trump split. How do you plan the play?

I decided to play for West having both of the outstanding Aces and for East to have exactly !H Q10 or Q9. Often I would have false-carded on this trick, playing the Ace in order to encourage a Spade continuation by West. That didn't suit me on this occasion. If I'd been more confident about East's !S length I might have even cashed the !S Ace, but I'd have had to be much more confident about an even trump split before I did that on this hand.

I won trick 1 with the King, therefore (so it was obvious I had the Ace as well) and crossed to Dummy's !D Ace (everyone followed small). At trick 3 I put my plan into operation and led a small Heart from Dummy. What I wanted was to get trumps drawn without allowing East to gain the lead to fire a Club through my hand. East played the !H 10 and when my Jack forced West's Ace, I knew I had much better prospects of making this hand. West switched to a second Diamond, which ran to East's  10 and my King.

Now another Heart and when West played small I went up with the King and dropped East's Queen, so the Heart position was now clear (West left with !H 96). Dummy's !H 8 now forced out West's 9 and I was home (I had 4 tricks already. Whatever West returned ( !H , !S or !D ) I could win, draw their last trump if necessary, and still had 2 Diamond tricks and a Spade ruff to enjoy for 9 tricks. In practice, West ran out of patience and led the !C Ace, so I ended up with 10 tricks - Bid Up! LOL.

I was, perhaps, a little lucky to find East with exactly what I was playing for, but even if East goes up with the Queen, my Jack will now force out the Ace on the next round so I'm in with a chance. Psychologically it's almost impossible for East to get this right and play the Queen on the first round. If West turns out to have !H AQxx I'm no worse off and there's always the chance of !H 109 doubleton with East. Worth noting that if I start with a small Heart to the King, I'm inevitably doomed to lose 3 Heart tricks including one critical one to East.


Unfortunately some EW idiot went -2 in 4 !S XX, so although we had the best result in Hearts (by 2 tricks), this triumph of hope over expectation only got us a couple of IMPs.

Hand 1 (Complete Layout). I demand a redeal - the !S Queen is missing and North only has 12 cards :)

Hand 2 is lovely. You have to assess this hand accurately: You need to engineer an entry to the North hand in Diamonds. No other suit will do. You can afford to lose 2 Diamonds tricks in order to achieve that, as long as you give yourself the best chance of reaching Dummy's Hearts.

(a) If the Diamonds are 2-1, reaching Dummy is never a problem (neither is getting 12 tricks). (b) If East has all three, you're irrevocably stuffed, but (c) when West has all three outstanding Diamonds, you can assure yourself of the entry by cashing the !S Ace at trick 2 and leading the !D 7 at trick 3. If West follows small, you overtake in Dummy. If East wins, the !D's are 2-1 and (a) above applies. If West wins trick 3 and East shows out, you simply win the return in hand, and lead the !D 5, once again overtaking if West plays low. If West goes up with the King, the 5 is now an entry with your carefully preserved 2. Cashing the other top !S at trick 2 is just in case Opps decide to give me a ruff 'n' sluff in Spades - doesn't really change anything)

Like I said, a peach of a hand. I just wish I could be confident that I would find the answer if presented just as a hand, without any suggestion that it was a problem! :) This is more of a problem at Match-pointed Pairs, of course. Do you give up the chance for 1 or 2 overtricks (by playing as above) or do you just lay down the Ace, hoping for a stiff King or any 2-1 split? At IMP scoring you would definitely play as above, assuming you analysed the problem correctly, but at MP Pairs I think you're effectively forced to get this one wrong by the scoring method.


There's a lot of these 'Concede a trick you don't have to in order to get more back in exchange' hands. One of Mollo's books has one where the Hog concedes a trump trick holding AKQJ1098 of trumps in order to endplay one of the opponents. There was also that hand from a simultaneous which I think I posted here a while back, you have to persuade one opponent to grab an opportunity to overruff in order to promote an entry card in dummy.

All good stuff, and a way to pass the time, but VERY long odds against you meeting the situation at the table, let alone recognising it if you do! As Oliver implies, it's much easier when you know it's a problem, because then you know that normal solutions won't work.

OCP really delivered the goods on this hand I played with Eszter yesterday:

EW Game, Dealer North

You are South, with:

South
 !S K863
 !H 93
 !D J1084
 !C A62

Bidding (Opps silent)
North     South
1 !S        1NT
3 !C        ??

Knowing Partner probably has !S AQxxx, and !C KQxxx makes it very easy to visualise 10 tricks wherever their red suit distribution was, so I had no problem bidding 4 !S even though we had to be well sub-minimum.

Eszter didn't quite have that hand, and that gave rise to an interesting issue in the play:

South (Dummy)
 !S K863
 !H 93
 !D J1084
 !C A62

!H 5 led

North
 !S A9542
 !H J2
 !D A
 !C KQ943

East led the !H 5. West took the !H AK and switched to the !S Jack. How should you play? At first sight it makes little difference. If the Spades are 2-2 you're never losing a Spade trick as long as you play for the drop. Similarly, if the !S Jack is a singleton, you are always losing 1 Spade trick, because East will have !S Q10x. What if West started with QJx or J10x, however, particularly the latter? If you win trick 3 in Dummy after East plays their singleton Queen, you now have a tenace of !S A9 sat over West's !S 107, but if you win this trick in hand, you must lose a trick to the !S 10.

For that reason, it's better to let this one run to Dummy and take the finesse on the way back if East "overtakes" Partner's Jack with the Queen

I had a bit of an uncontrollable giggle on this hand (which nobody else heard but me, of course). Imagine this hand:

Game All, Dealer West

You are North, holding

North
 !S K3
 !H K9652
 !D K7
 !C Q654

Bidding (Opps silent)
North     South
1 !H        1NT
2 !C        3 !C
All Pass

South (Dummy)
 !S 64
 !H Q10
 !D J865
 !C AKJ109

!S Ace led

North
 !S K3
 !H K9652
 !D K7
 !C Q654

East follows the !S Ace with the Queen, West echoing with the 7 and then the 5. You play 2 rounds of trumps ending in hand. West discards a small Diamond on the second round of trumps. Now a Heart to the Queen loses to West's Ace and their return of the !H 3 crashes your King, Dummy's 10 and East's Jack.

Partner (Paula in the North seat) ruffed a Heart in Dummy, cashed one more round of Clubs (on which West discarded the !S 8) and then led a Diamond off Dummy, on which West played small and East contributed the 9. A second Diamond from Paula was won by East's Queen and they now played a 3rd round of Diamonds, their 10 covered by Dummy's Jack and West's Ace and ruffed in hand.

What now?

Declarer, if they've counted the hand, should know exactly where every card that matters lies:
We've won 8 tricks. The position is now known to be

                 South (Dummy)
                 !S -
                 !H -
                 !D 8
                 !C K

East                           West
 !S ?                            !S ??
 !H 7                            !H -
 !D -                            !D -
 !C -                            !C -

                 North
                 !S -
                 !H 96
                 !D -
                 !C -

You've heard of "Loser on Loser" plays. Well this contract was never in doubt and 3 !C was a very good score, because lots of NS Pairs either stretched too far and/or didn't get the considerate lead of the !D Ace at trick 1, but Paula now came up with a new concept, the "Winner on Loser" Play :) :

The !H 9 was good and the !D 8 was good (East had played the Q, 10 and 9, West the Ace and West discarded a small Diamond on the 2nd trump), so Paula had multiple options here to take the last 2 tricks: cash the !H 9, discarding the !D 8  and then ruff the !H 6, of ruffing either Heart and then cashing the !D 8. Paula chose a 3rd option, which was to lead the !H 6 (the losing Heart) and then discard the good !D 8 when West covered with the 7.

A "Senior Moment" or a misclick, I suspect, but it was quite funny at the time. :)
