Just now in Cayne vs. Fantoni (hand rotated for convenience)...

Nunes opened 2, Seamon balanced with 2, and Cayne raised him to 4. Seamon then engineered this end position...

Scoring: IMP

South on lead needs 4
more tricks to make 4.


The question is, what is this squeeze called? Wikipedia says a guard squeeze is a squeeze where one defender is squeezed with a card which protects his partner from a finesse, which doesn't quite apply here (but of course Wikipedia may be wrong).

This is a three suit squeeze on WEST with a development threat. The three suit nature of the squeeze compensates for the fact that in the six card ending, NS have only three winners (loser count = 3), and there are not one, but two developmental threats (spades and diamonds).

On the last heart, WEST has three ways to give. IF he throws a club, it sets up the club trick. If he throws a diamond, diamond Ace and a diamond establishes a diamond trick, and if he throws a spade, spade Ace then ten leads to setting up the dummys spade nine per force.

So it is a triple squeeze (west in three suits) with two developmental threats. A normal "development squeeze" (what clyde love called a CLE squeeze for companion, lead entry) occurs in two suits, this is a three suit version of the same development squeeze. It is interesting that both developmental threats have entries in the threat suit held by the other hand. So you might add criss-cross to the name. How about A criss-cross double developmental triple squeeze?

Scoring: IMP

At the other table, Garozzo lead the the 10...
is there any way to make the contract now?


Criss-cross double developmental triple squeeze... I like it, Ben! :)

Presumably not. For the developmental squeeze to work, you need an entry to both developmental threats after the last heart is played. After the heart lead, when a club is ducked (eventually), a diamond lead will remove the entry to the threat. And in most cases a spade lead will remove an entry needed too for the criss-cross nature of the squeeze. Note after the club king lead, the contact can still be set if they knock out the diamond entry. But looking ahead to break up a criss cross double developmental triple squeeze at trick two requires considerable, impossible? planning.

I would have called it a "triple squeeze without the count"

I would have called it a "triple squeeze without the count."

Multi-loser squeezes are often called "squeeze without the count". As your comment points out, a triple squeeze typically has two losers (triple squeezes can also have only one loser, but then the victim is really mincemeat). So while non-triple squeezes with multiple losers are often called "squeeze without the count", and it might be logical to extend that definition to triple squeezes with more than two losers, this blurs some fine distinctions between hands.

Let's consider "squeeze without count" hands. What types are there? I can think of at least four general types off the top of my head.

1.) A developmental threat. For a developmental threat, by losing a trick in a suit, we develop an extra winner. On this hand there are two developmental threats (diamonds and spades). Development squeeze work when loser count is one greater than the "correct count". So for a two suit squeeze, the loser count has to be "2", for a three suit squeeze, the count has to be "3". Sometimes the squeeze will repeat to gain two tricks when in the context of a triple squeeze and losers count is "3" (such triple squeezes that work where loser count is higher than 3 is rare, unless... see next type).

2) Strip endplay - is where by losing a trick to an opponent you receive a favorable return that gains a trick (the "squeeze" here generally removes excess winners and/or cards of exit). The loser count can be any... Even wiht five losers, this type of play can gain one trick.

3) Losing Card Squeeze. Here the "squeeze card" just happens to be a trick won by the victims partners. In a triple squeeze setting, the loser total has to be "3" and when you lose a trick to your victims partners, he can not have another winner to cash, obviously.

4) Guard squeeze plus developmental threat: This is a type of three suit squeeze without a count where in addition to the a developmental threat, one option the opposition has is to expose his partner to an immediate finesse. Like the case with a developmental threat, this on works with a loser count that is too high by one.

I suspect there are more combinations we can think of if we try. But if you lump all of these into one category "triple squeeze without the count", it will be hard to recongize them at the table, and you do not convey the nature of the squeeze play very accurately. You need some context in which to examine the nature of your threats early in the hand in order to manipulate the play to the corresponding ending. Also, it turns out, for instance, that a triple squeeze with a developmental threat has the "correct count" when loser count is "3", as it is a different squeeze than a normal triple squeeze, just as a two suit squeeze with a developmental threat or a losing card squeeze has a "correct count" when loser count is "2". That is, the correct count for these "squeezes without the count" is one more than normal. While a strip squeeze the loser count can be anything.... by classifying them correctly, you also can try to "correct" the count to what is needed (see the duck of the first club, to go from four losers to three on this hand, as an example).

The unique this about the hand shown is that there are two developmental threats, and when setting up the developed threat, it doesn't ahve to be the victim of the squeeze that wins the trick. Give West KQJ of spades rather than QJx and it is a normal triple squeeze with a single developmental threat. But here, West had to keep the QJ of spades to prevent declarer from developing a spade trick. This is sort of a the developmental squeeze equivalent to a guard squeeze (rather than protect partenr from a finessee, you have to protect him from being exposed to a developmental play in spades). Note, swap the spade Queen with a small spade in his partners hand, and the squeeze fails. Why? Because you have just turned the triple squeeze into a double squeeze but the loser count is off by two for a simple squeeze with a developmental squeeze.

I never said it was a particularly good name for it though.

Scoring: IMP

How can this squeeze be found at the table? The bidding was,

WEST NORTH EAST SOUTH
 2      Pass     Pass  2
PASS    4  All Pass

2 showed 10-13 hcp, 5+. This gives some important clues. Like when club king was lead (from KQ) without the TEN (south has that), then low club to trick two.. West is marked with club JACK probably to three (UDCA carding) (8,9). Leader not DKQTxx or DKQ9xx as that would be better than club king lead. So 5-4 in the minors, or maybe 6-4


KQ of hearts, club ruff, tells the story for sure. EAST has a diamond honor (K or Q, heart J), WEST has diamond honor, club KQ, so needs at least three points in spades, and doesn't have KQJ (better lead choice). The distribution is surely WEST 3-1-5-4 or 2-1-6-4.

What about chances to make? Diamond threat (3rd round) surely against WEST, loser count is 3, spade honors surely split, club threat against WEST. But notice if you try to correct the count, they will lead diamonds until you are forced to win teh diamond ACE. With the diamond ACE gone, there will be NO ENTRY to North after any squeeze play as you will be out of trumps there to effect a squeeze.

So no way to "correct the count" for a diamond/club squeeze against WEST (not to mention they can blot out the club threat after you ruff one). So you just have to live with a loser count of three, as there is no way to "correct it". If you look at the last group, you will realize that you need a triple squeeze plus something extra. I surely doubt all but world class players would find it. But, knowing that if you try to duck a trick, all squeeze endings can be killed by a diamond return, and knowing that with three losers, you need either a strip endplay or a developmental threat and three suit squeeze gives you a chance to evaluate which is most likely. The only possible endplay is to force a diamond from KQ from WEST, but the decision was that WEST can't have that for the bidding/lead. So... developmental threat with a triple squeeze is the only option. So this can be found at the table, as clearly the world class player (seamon) demonstrated brillantly.
