Counting is the key, though, Brian:
  • East opened the bidding so they have at have at least 11-12 HCP
  • That in turn means that West is unlikely to have more than 3 HCP, probably less.
  • Since you cannot stop East from taking their !S Ace at some point there is no way you can make this contract if the Diamonds are 5-3.
  • Thus you have to base your play on the assumption that the Diamonds are 4-4.
  • Note that you don't really lose anything if it turns out that the Diamonds are 5-3 after all.
  • Once East shows up with a singleton Club, then if the !D are 4-4 (your assumption) East must be 4441 or they would have a 5-card Major and would have opened that instead of 1 !D.
  • Now you can count the hand and plan to get them down to !S Ax, !H Kx, !D Q, !C - when you play the 5th round of Clubs.
  • Whether they discard the small Spade or blank their !H King you can now endplay them with a !S or drop the singleton King of Hearts.
If instead they discard the !D Queen then you just have to credit their expert play  -  you gave it your best shot. Now they can exit to the Spade Q in West's hand and West can either cash a long Diamond or lead a !H through. Not many defenders will think of chucking a sure-fire winner in order to keep an exit card, however.

Please note, guys, this is not a "Hail Mary" play. Playing for West to have the !H King  and East to have !H 10x would fall into that category, for sure. Giving East the !S Ace, !H King and !D KQ is entirely consistent with the bidding and West's opening lead of the !D Jack.

Interesting Play Hands / An Instructive Hand for Assumptions & Counting
« on: January 04, 2022, 08:36:15 PM »
Hi All,

This was a very instructive hand I came up against earlier today while playing with Servet.
You are South at Green vs Red and end up in 3NT after the following auction:

North
!S 982
!H A95
!D 94
!C AJ1074

South
!S K4
!H QJ7
!D A102
!C KQ985

Bidding:
North     East    South    West
No          1 !D     1NT       No
3NT       All Pass

Yes, my 1NT was a little pushy, but Servet's 3NT was bang on.
West led the !D Jack which did not look too promising for the Diamonds splitting 4-4. That won the first trick, East's King took the second round and East then continued the !D 7 on the 3rd round, West following with the 3 and then the 6, while I discarded a Spade from Dummy on the 3rd round. How do you take stock of the hand? At first sight it looks fairly hopeless as Opps will almost certainly make 3 Diamonds, a Spade and a Heart.

Well firstly, you have to make the assumption that the Diamonds really are 4-4, because on the bidding East surely has the !S Ace and !H King to go along with the !D KQ. If East has 5-card Diamonds you are definitely off. In retrospect the best tactic here is to play a Club to the 10 and lead a Spade, because East is more likely to hold up their Ace (which is essential for you) if you play a Spade early on.

I decided to put them under a little pressure first, however, and get a better count on the hand so I played 4 rounds of Clubs ending in Dummy, to which West played 2 Clubs and 2 Hearts and East played 1 Club, 2 Hearts and a Spade.

East had to be 4441 and West 4342 to start with if our assumption about the Diamonds is correct. Now I played a Spade and went up with the King with East played low. Now I had him: I cashed my 5th round of Clubs (East throwing a Spade) and then exited with a Spade to endplay him. He could take his !D Queen, but then had to lead away from !H Kx.

A simple enough endplay but easy to miss if you're not counting the hand. Once you make the assumption that the !D's have to be 4-4 that really limits the number of HCP that West can have when they do not bid 2 !D with 4-card !D support for partner, which 100% rules out them having the !H King. When they show up with the !D Jack at trick 1, the most they can have is the Jack or possibly the Queen of Spades. Also, once East shows up with only 1 Club, they have to be exactly 4441 if you assumption about the Diamonds is correct or they would have opened a 5-card Major. Once you have that straight it's easy to count their discards and even drop their !H King if they get tricky and blank it in order to keep 3 Spades.

A better player than the East I faced might well have discarded 3 small Hearts and only a single Spade on the last Club to try to fool you into taking the !H finesse. They would certainly have spotted the endplay coming a mile away and gone up with the !S Ace on the first Spade trick, cashing the !D Queen and then exiting with a Spade to wait for their !H trick. You have to give Opps a chance to go wrong when the situation seems hopeless, though.

Interesting Play Hands / Double Bath Coup and a Triple Squeeze!
« on: January 02, 2022, 01:05:58 PM »
I really enjoyed this hand in a TM with Servet today:


North
 !S AJ
 !H Q7
 !D K10973
 !C K876


 !C 3 led


South
 !S Q103
 !H A63
 !D J54
 !C AJ95


Bidding:
South      West      North    East
1NT          No         2 !D      No
2 !H         2 !S        2NT      No
3NT         All Pass


Dummy's !C 6 could have won the first trick, but I took it in hand with the 9 and led the !D 4 to West's Queen, Dummy's King and East's Ace. East thought for a while and then switched to a Spade, taken by Dummy's Jack. I decided then that West had started with !S Kxxxx, !H Kxx, !D Q and !C Q10xx to justify his 2 !S bid and that he was vulnerable in 3 suits . To make sure I took the !D Jack and another !D (West showing out as expected).

So we now have

North
 !S A
 !H Q7
 !D 107
 !C K87

South
 !S Q10
 !H A63
 !D -
 !C AJ5

The key to making 12 tricks was now a bath coup in both Majors: I led the !H 7 to my Ace and the !S 10 back to Dummy's Ace and then ran the last two Diamonds, discarding Hearts from hand. On the last Diamond West, now down to !S K, !H K and !C Q10x had to let something go and discarded the !S King. Now I could cross back to the !C Ace in hand and cash the !S Q, squeezing him again in !C and !H .

...before the last Diamond:

North
 !S -
 !H Q
 !D 7
 !C K87

South
 !S Q
 !H 3
 !D -
 !C AJ5

The opportunities for triple squeezes don't come up very often. It was satisfying to spot the opportunity as early as trick 2, based on the bidding and the fact that East couldn't beat the !C 6 on the first trick and West obviously having the stiff !D Queen at trick 2.

Making 3 overtricks was a great result. At the other table the same contract got a !S lead. Declarer won with the !S Jack, took the losing !C finesse and when West knocked out the !S Ace at trick 3 Declarer was unable to recover and went one off.

Interesting Play Hands / Tempo
« on: July 07, 2019, 06:56:07 PM »
Playing in tempo can be extremely important. Sometimes the slightest hesitation can give the game away, and your subtle subterfuges will all come to naught. Often you have to try to anticipate what might happen so that you can be ready to play in tempo so as not to give the game away. Holding up your King with Kx when Dummy holds AQJxxx in a suit with no side entries is a well known ploy (when you think Declarer only has 2 of the suit).

Another situation came up today in a hand I played with oktay. You are North, the Dealer at Game All. You are holding

North
 !S A432
 !H Q7
 !D QJ3
 !C J954

After 2 passes, partner opens a weak 2 !H . This is passed round to East, who protects with 3 !C , and West's 3NT ends the auction. You select the !H Queen as your opening lead and Dummy goes down. This is what you can see:

East (Dummy)
 !S Q65
 !H 9
 !D K94
 !C KQ10872

                North
                !S A432
                !H Q7
                !D QJ3
                !C J954

Using o/e signals, Partner plays the !H 4 on trick 1, which Declarer wins in hand with the King. Declarer cashes the !C Ace (Partner contributes the 3) and then tanks for half a minute. What are you thinking about in the meantime?

The play at trick 1 suggests that Declarer has !H AKxx or AK10x. You know about the !C Ace, but the current pause suggests that Declarer started with the stiff !C Ace, as otherwise his second Club would have hit the table already. Declarer will also have either the !D Ace or the !S King, but probably not both of those cards, or Partner will have opened vulnerable with something like a 2-count. If Partner has the !S King then you cannot prevent an entry to Dummy in Diamonds, but if Partner has the Diamond Ace, the whole hand might revolve around trying to prevent Declarer from reaching Dummy with the !S Queen. It's entirely possible that the hand is going off whatever the position, because you know Declarer probably only has 1 entry to Dummy, and the Clubs are not going to run, and if Declarer has the !S King you cannot prevent them from reaching Dummy with the Queen, but you need to work the hand out as best you can.

After his tank, Declarer plays the !S King. If you hesitate, even for a moment, especially if you going to duck, then you've given the game away, because you only have something to think about if you have the Ace. If you end up taking the trick, a pause doesn't matter, but a pause before ducking is foolish. oktay thought for about 10 seconds and then ducked.

As it happened, Declarer was clearly not paying any attention, because he then played the !S 10 and then, after another pause, ran it and lost to partner's Jack. A 3rd Spade went to your Ace (all following) and you could cash your 4th Spade (Dummy & Declarer discarding Diamonds and Partner a Heart) before leading the !D Queen, allowing partner to take Declarer's King with their Ace and return a Diamond to your Jack. You exit with your 3rd Diamond and Declarer has to concede 1 Heart trick to South for -2.

This contract was probably doomed from the start, but you have to realise that You can work out that Partner has the !D Ace or the !S King, but Declarer cannot be sure. From their viewpoint South might or might not have the !S Ace and/or the !D Ace, so best to keep them guessing.

Interesting Play Hands / Re: A Nice Burns Law Violation

I concede defeat :)


It is one of the really nice things about gadgets such as Amsbury and Panama, because Opps either have to allow you to escape undoubled, or give you a chance to get into something better by doubling.

Interesting Play Hands / A Nice Burns Law Violation
« on: June 26, 2019, 10:29:48 AM »
Metin and I had a chuckle about this hand, which played quite nicely (with a little help from Opps): You're North, the Dealer, with NS Vulnerable. You open 1 !D (Complex Sys) and this is passed out. East leads the !H King and this is what you can see:

South (Dummy)
!S J642
!H 86
!D 102
!C KQJ42

!H King led

North
!S 105
!H A95
!D A95
!C A8763

Not promising - this could easily end up as -3 if Opps attack trumps.

Metin took the first trick and exited with a Heart. East won and obligingly continued the suit, allowing Dummy to ruff. Metin exited with a small Spade to his 10 and East's King. East even more obligingly played a 4th round of Hearts allowing Dummy to ruff and Declarer to discard his other losing Spade.

Now a Spade ruff, a Club to Dummy's King and a second Spade ruff allowed Metin to make every single one of his trumps separately. That rare score of +70 was worth 2.2 IMPs even though 3 !C is trivially easy, because 10 tricks in Hearts are fairly easy for EW whether they bid game or not.

Ok, this needed a lot of help from East but there is something very pleasing about escaping the hangman :)

Interesting Play Hands / A Unlikely Game
« on: June 09, 2019, 07:58:47 PM »
Bridge is a really weird game at times. Take this hand that Eszter and I played earlier today. You are North, EW Game and East is the Dealer.

Bidding
East     South     West     North
2 !S      3 !C         3 !S       4 !H
No        No            X          All Pass

East led a small Diamond against 4 !HX and this is what Eszter could see:

South (Dummy)
 !S Q8
 !H 73
 !D 72
 !C AKJ10965

 !D 4 led

North
 !S 75
 !H AJ1098
 !D AQJ108
 !C 3

Not a very promising looking game. 3 certain losers in the Majors and it doesn't look as if the Hearts will be splitting nicely. Moreover Declarer has only one sure entry to dummy to take a Heart finesse.

Still things look up when West plays the !D King at trick 1. Eszter tried the !D Queen at trick 2, but East ruffed low and exited with a small Club. Eszter rose with the Ace and dropped West's singleton Queen. What now?

Well things are certainly looking a little more promising now the Minor suit position is known. Eszter continued with the !C King, West ruffed low and Eszter overruffed. Now the !D Jack produced the !H King from East and Eszter discarded a Spade from Dummy. East cashed the !S King and then continued with another Club, ruffed by West and overruffed by Eszter (I think a Spade continuation gives Declarer little or no chance). Eszter had now lost 3 tricks, but was in full command: She ruffed a Spade with Dummy's !H 3 and put West to the sword with the !C 10.

At this point, West could have made it slightly more awkward for Eszter by not ruffing. Eszter would then have to deliberately shorten her trumps by ruffing Dummy's winner, then ruff the !D 8 with Dummy's last trump and then lead the !C 9 to leave West nowhere to go. This was the interesting position after Dummy ruffed Eszter's 2nd Spade.

South (Dummy)
 !S
 !H 7
 !D -
 !C 10965

North
 !S -
 !H AJ10
 !D 108
 !C -

West is known to have !H Q6, !D 96 and a Spade (probably the Ace or East would have opened 2 !S with an 11-count). Eszter has to get the timing right if West doesn't ruff the !C 10. If West discards a Diamond and Eszter doesn't shorten her trumps immediately she will be unable to return to Dummy for the final trump coup. As it happened West obligingly ruffed, allowing Eszter to overruff for the 3rd time, return to Dummy by ruffing her !D 8, and then applying the coup de grace by leading the !C 9. If West ruffs with her Queen, Eszter overruffs and her hand is now good. If West discards her !S Ace, Eszter simply discards the !D 10 and can claim the final trick.

Well done Eszter! (...even if I disagree with the 4 !H bid LOL)

Interesting Play Hands / A Tricky One
« on: May 28, 2019, 08:14:11 AM »
Eszter shone in her play of this tricky hand. You are North at Love All and the bidding has gone:

South     West     North     East
No           1 !D       2 !C        No
No           X           All Pass

East led the !D 6 and this is what Eszter could see:

South (Dummy)
!S J10
!H QJ2
!D J109532
!C Q6

North
!S AQ84
!H A54
!D 8
!C A10832

Yes, it could have been worse but it was clear East had a Club stack and a Diamond shortage. West took the opening lead and continued with the !D Ace. Eszter ruffed low and was overruffed by East, who exited with a small Heart, which went Queen, King, Ace. Eszter wisely resisted the urge to do anything with trumps early on, crossed back to the !H Jack and led the !S Jack. West covered and Eszter took her Ace.

Now Eszter led a small Club. East played low and West's singleton Jack fell under the Queen. Eszter cashed the !S 10 and exited with a Heart, which was won by East's 9 (Given East's lead of a small Heart earlier, West probably thought this was getting ruffed, but I think they should have risen with the 10 regardless).

East was now comprehensively endplayed. He tried exiting with the !C 9, but Eszter won her 10 and then played the !S Queen and exited with her last Spade to endplay East again for a valuable doubled overtrick.

Well played! The trick here was to resist the urge to play on trumps too early and then to only lead them once. East was always going to be vulnerable to being endplayed by their own trump length.

Interesting Play Hands / Assumption is the Mother of all...
« on: May 18, 2019, 10:27:07 PM »
Metin (Arda85) and I had an interesting session this morning with Metin trying his hand at the Complex Sys (with a good degree of success). One hand well pointed up the inadvisability of  interfering against multi-style openings until your Opps have clarified their hand somewhat.

At game all I opened 2NT on the following motley collection:

 !S AJ1042
 !H J10843
 !D Q
 !C KQ

My LHO clearly assumed I had the Minors or Clubs and overcalled 2 !H . Metin doubled and I was perfectly happy to pass that for penalties. Metin was in the very happy position of knowing that I must have the Majors, because he was sat with

 !S K3
 !H 9
 !D AK106
 !C AJ10972

Poor Declarer was sat with !H AKQ52 and the Spade Queen and Dummy just had !D Jxxx. When the dust settled we let Declarer off with -4 for 1100 (could have got one more with perfect defence). One pair found and made the vastly inferior Spade slam but nobody found the much better Club slam and +1100 was pretty good.

This kind of situation is similar to Brozel/DONT Doubles over 1NT and defending against a Multi. You really are generally better off letting Opps define their hand-type before you jump in with both feet. Sometimes if you're 4th-in hand, you don't have that option, but when you're 2nd-in-hand over the Multi-style opening, you usually can count on a 2nd chance.


We had one nice bidding hand for the system, which was rewarded with a top. Metin responded flawlessly on this:

NS Vulnerable, Dealer West

North
 !S J8
 !H AK104
 !D AK
 !C 108643

South
 !S AK1074
 !H 63
 !D AK
 !C AKQ5

Bidding (nothing from Opps)
North          South
1 !D              1NT(1)
2 !C (2)          2 !D (3)
3 !H (4)          4 !C (5)
4 !D (6)          4 !S (7)
5 !C ( 8 )        7 !C (9)

(1) 14+ any shape
(2) 5+ Clubs
(3) Range Beta
(4) Max, 6 Controls
(5) Gamma in Clubs
(6) No Top Honour
(7) Epsilon in Spades (To guard against !S xxx)
( 8 ) 3rd round control of Spades
(9) Knew North couldn't have the !S Queen with AKAK in the Reds, so wasn't remotely tempted to try for 7NT.

The Clubs were 3-1 but the Spades were 3-3 so no problems. Amazingly, nobody else found 7 !C and the Grand was worth 15 IMPs. Overall, Metin showed a very good grasp of the system, so please give him a game if you get the chance.

Bidding Challenges / Re: MOTOR and Lebensohl Nuances
« on: May 16, 2019, 11:59:43 PM »
I wouldn't say it's a "requirement", even now. The idea behind the suggested holding for a redouble is that a 6-1 or 7-0 opposing trump split might cause opener some problems in 1MXX even if we definitely hold the balance of the HCP and the opposing long trumps are under Declarer. Obviously Responder won't be better then Hx in Opener's Major, but we also want to be sure that 1MXX is going to make. :)

Bidding Challenges / Re: MOTOR and Lebensohl Nuances

(3) and (4) are easy in the sense that they are "normal" Leb sequences. 2NT is Leb and 3NT is "fast", and therefore lacking a Heart Stop and presumably with good long Diamonds.


It's (1) and (2), particularly (1), that are a bit more interesting to me. I know what I've written on the MOTOR sections, but...


I wonder if there really is much point in either of them being natural in any way at green vs red, especially (2), because Responder would have a fairly obvious Redouble over 1 !S - (X) - ??. I can't see much sense in (1) being Leb either, because MOTOR already gives us so many different ways of expressing different hand-types. Even if Responder has a Spade shortage here, a Redouble seems very attractive once Responder is 11-12 (let alone 13+) and if the Spade split is bad, the opposing Spade length will be underneath Opener, which is probably good for us.


At red vs green, natural and invitational, or natural and GF makes perfect sense but I do now wonder whether it's worth reconsidering their meaning at favourable vulnerability.


I'd be interested to hear other people's view on this.

Correct (?) Answers to Bidding Problems / Re: 001 OVER INTERFERE
« on: April 28, 2019, 09:18:50 PM »
LOLOL ...I was just going to say, you cannot have a "tentative" game force. A bid is either game-forcing or it isn't. A positive response to 1 !C, playing OCP or Precision, is 1,000,000% game-forcing!!!! A bid cannot be 50.0001% GF :).

14
Anti-system or not, Brian, it's just plain common-sense. I do exactly the same with that hand type. The fundamental point here is that if Opener has shown an intermediate hand, the basic principal is that they cannot initiate a game-forcing sequence and in most instances cannot initiate any kind of forcing sequence except maybe an occasional bid that is forcing for 1 round (eg: new suit at the 3-level), but the likelyhood is that even there the whole sequence will probably be forcing because of a bid that Responder has made.


Yes, Jimmy, Responder (and Opener) should keep the bidding open if they think their hand warrants it, but that's a million miles away from the sequence being forcing.

15
1 !D - 1 !H - 1 !S is eminently, 100% and utterly passable, as Brian says. Opener has limited their hand by Opening 1 !D. Nothing they bid is forcing in any subsequent [natural] sequence, unless a forcing sequence is initiated by Responder.


This 1 !D - 2 !C - 2 !H is forcing, not because 2 !H is forcing, but because 2 !C is effectively forcing to 2NT and now Opener has reversed into 2 !H.


Similarly 1 !D - 1 !H - 2 !C - 2 !S - 3 !D is forcing, but only because the 2 !S reverse is 100% GF.


Bottom line is that it is effectively impossible for an intermediate Opener to initiate a forcing sequence. The impetus for that almost always comes from Responder. The only real exceptions would be splinters by Opener (eg: 1 !D - 2 !C - 3 !H, which would be violently agreeing Clubs and showing a Spade shortage).
