In a **Guard Squeeze**, a single opponent is pressured in three different suits. Within those three suits, the opponent holds a specific card (a **finesse guard**) which, if discarded or unguarded, allows the Declarer to successfully finesse their partner in that suit.
#### **Essential Requirements for a Guard Squeeze:**
* **Correct the Count:** You must have only one loser remaining (i.e., you can win all the remaining tricks but one).
* **The Basis Threat:** You need a basic threat, and the opponent sitting to the right of the hand holding this threat must be the one guarding it.
* **The Finesse Threat:** A suit where a finesse is possible must be present.
* **The Third Threat:** In addition to the basic and finesse threats, a third threat suit is required.
* **Communication & Timing:** The finesse threat must have exactly **one protector** remaining when the squeeze card is played; otherwise, the squeeze will fail.
* **Avoiding Blockage:** If the finesse threat is blocked, the squeeze will not work.
In this post, we will skip the *Simple Guard Squeeze* as it functions similarly to a standard double squeeze and focus on the two main types of **Double Guard Squeezes**:
1. **Type L Double Guard Squeeze**
2. **Type R Double Guard Squeeze**
---
### **Type R Double Guard Squeeze**
In this specific variation, the **basic threat** sits in isolation (**opposite the hand containing both the finesse threat and the third threat**).
**The Mechanics:** The opponent sitting to the left of the finesse threat is squeezed. They are forced to discard their **finesse guard**, which immediately creates the opportunity for the Declarer to finesse their partner in that suit.
### **Executing the Type R Double Guard Squeeze**
In this complex scenario, leading the **♠️A (Squeeze Card)** from the South hand forces both opponents into a critical decision. Let's break down the two possible defensive lines:
#### **Scenario 1: East retains the Finesse Guard**
1. South cashes the **♠️A**. **West** discards a Heart.
2. If **East** chooses to discard the **♦️A**, South proceeds to cash the **♣️A**.
3. Now, **West** is caught in a secondary squeeze:
* If West discards the **♦️K**, North’s **♦️Q** is promoted to a winner.
* If West **unguards the Hearts**, North’s **♥️9** will capture the final trick.
#### **Scenario 2: East discards the Finesse Guard**
1. South cashes the **♠️A**. If **East** decides to discard the **♥️K (the Finesse Guard)**:
2. South cashes the **♣️A**, while North discards the now unnecessary **♦️Q**.
3. South then leads the **♥️3**, allowing North to successfully execute a **finesse with the ♥️9**.
---
### **Key Concept: The B (Both) Threat**
A **"B Threat"** is a card that both opponents are forced to guard simultaneously. In the provided diagram, the **♦️Q** in the North hand is a B-threat because it is guarded by **West’s ♦️K** and **East’s ♦️A**.
> **Strategic Rule:** If the **Squeeze Card (♠️A)** were located in the North hand instead of South, the South hand would require an **entry** in at least one of the three threat suits to maintain communication and complete the squeeze.
### **Type R Guard Squeeze: Execution from the Opposite Hand**
When the final squeeze card is located in the hand opposite the basic threat (in this case, North), the Declarer must carefully manage entries and "unblock" specific cards to maintain communication.
#### **Scenario 1: East discards a Heart (The Finesse Guard)**
1. **The Lead:** North cashes the **♠️A**.
2. **The Unblock:** East discards a Heart. Crucially, South must **unblock the ♥️10** to ensure future communication.
3. **The Entry:** North leads the **♥️3**, and South wins with the **♥️K**.
4. **Cashing the Winner:** South cashes the **♣️A**, while North discards the now unnecessary **♦️Q**.
5. **The Final Stroke:** South leads the **♥️2**, and North wins the final trick by **finessing with the ♥️9**.
#### **Scenario 2: East discards the ♦️A**
1. **The Lead:** North cashes the **♠️A**. East discards the **♦️A**.
2. **The Setup:** South again **unblocks the ♥️10**, and West discards a Heart.
3. **The Entry:** North leads the **♥️3** to South’s **♥️K**.
4. **The Second Squeeze:** South cashes the **♣️A**. Now West is squeezed:
* If West discards the **♦️K**, North’s **♦️Q** becomes a winner.
* If West discards another Heart, North discards the **♦️Q**, and South’s **♥️2** leads to North’s **♥️A** and **♥️9** for the final tricks.
> **Defensive Note:** In both scenarios, East cannot afford to unguard the **♣️KQ**. If they do, South’s **♣️AJ** will capture the remaining tricks immediately after cashing the **♣️A**.
---
### **Strategic Insight: Flexible Entries**
It is important to note that the necessary entry into the South hand does not always have to be in the finesse suit. The squeeze remains effective as long as South has a guaranteed entry in **any other non-finesse threat suit**, allowing the Declarer to maintain control after the opponents have been forced to discard.
### **Strategic Entry in Non-Finesse Threat Suits**
In this position, the required entry to execute the squeeze can be located in any of the **non-finesse threat suits**. This flexibility allows the Declarer to adapt their communication based on the defensive discards.
#### **The Execution:**
1. **The Squeeze Card:** North leads the **♠️A**.
2. **East's Dilemma:** East is forced to **unguard Diamonds**.
3. **South's Response:** South discards a low Club, and West discards a Heart.
4. **Transition:** North leads the **♦️4**, and South wins with the **♦️A**.
5. **The Final Pressure:** South cashes the **♣️A**, placing **West** in a terminal squeeze:
- If West discards the **♦️K**, North’s **♦️J** is promoted to a winner.
- If West discards a Heart, North’s **♥️J** becomes the winning card.
### **The Critical Rule: Protection Limits**
A vital requirement for this squeeze to function is the number of "protectors" in the finesse threat suit.
> **Important Note:** When the squeeze card is played, the finesse threat must have **exactly one protector remaining**. If it has two or more protectors at that moment, the squeeze will fail, as the defense will have enough cushion to avoid being compressed.
### **Extended Analysis of Type R Guard Squeeze**
In the position shown above, if South leads the **♠️A**, West will discard a low Heart and East will discard the **♥️7**. As a result, the squeeze will fail.
To successfully execute the squeeze in this scenario, a **Heart winner** must be cashed first. Then, when North leads the **♠️3**:
* If **East** discards the **♥️Q (Finesse Guard)**, West becomes vulnerable to a Heart finesse.
* Consequently, **East** is forced to discard the **♦️K**, while West discards a Heart.
* Now, when South cashes the **♣️A**:
* If **West** discards the **♦️A**, North’s **♦️Q** is promoted to a winner.
* If **West** discards a Heart, North discards the **♦️Q** and after cashing the remaining Heart winner, the **♥️9** will win the final trick.

### **Type L Double Guard Squeeze**
In a **Type L Double Guard Squeeze**, the finesse threat stands in isolation (opposite the other threats), and the last **F winner** (Free Suit winner) is located in the same hand.
**Essential Requirements:**
* **The Guard:** West must hold the guard for the finesse threat to protect their partner (East) from being finessed.
* **The Entry:** The North hand must have a solid entry so that leading a finesse suit from North allows the finesse to be executed in the South hand.
### **Type L Double Guard Squeeze: Entry in the Basic Threat Suit**
In this configuration, the required entry in the North hand is the **♣️A**, which also serves as the protector for the basic threat.
#### **The Execution:**
1. **The Squeeze Lead:** South leads the **♠️A (Squeeze Card)**.
2. **West's Dilemma:** * If West discards the **♥️Q**, East becomes vulnerable to a finesse in Hearts.
* Consequently, **West is forced to discard the ♦️K**.
3. **The Discards:** North discards the now-useless **♣️J**, and East discards a low Heart.
4. **Cashing the Entry:** South proceeds to cash the **♣️A**. Now, **East** is squeezed:
* If East discards the **♦️A**, North’s **♦️Q** is promoted to a winner.
* If East discards a Heart, South’s **♥️J** becomes the winning trick.

### **Variation: Unprotected Basic Threat**
It is important to note that if the North hand possesses an entry in **any other suit**, the squeeze remains perfectly functional even if the basic threat is "unprotected" (i.e., has no protector in the North hand).
> **Strategic Insight:** The flexibility of the entry allows the Declarer to maintain pressure regardless of which suit provides the communication between the two hands, provided the fundamental threats remain intact.
### **Type L Guard Squeeze: Entry in the Finesse Suit**
In this scenario, the required entry to the North hand is located within the finesse suit itself (**the ♥️K**).
#### **Strategic Observation:**
In this specific position, the Hearts in the North hand do not technically function as a **finesse threat**, because the other two threats (Diamonds and Clubs) are also located in the North hand.
#### **The Execution:**
1. **First Squeeze Card:** South leads the first **♠️A**.
* If **West** discards a low Heart, North must **unblock the ♥️9**. **East** discards a low Diamond.
2. **Second Squeeze Card:** South leads the second **♠️K**. Now **West** is under pressure:
* **If West discards another Heart:** South can cash the **♥️K** and then lead another Heart to execute a finesse in the South hand.
* **If West discards the ♦️K:** North discards the now-useless **♣️K**. This immediately puts **East** in a squeeze.
* If **East** discards the **♦️A**, North’s **♦️Q** is promoted to a winner.
* If **East** discards a Heart, South cashes the **♥️K**, leads toward the **♥️A**, and the South hand's remaining Heart captures the final trick.

### **Conclusion on Entries**
As demonstrated across these examples, the **Type L Double Guard Squeeze** is highly versatile. While we have shown entries in the basic threat suit and the finesse suit, the squeeze remains effective even if the entry to the North hand is located in **any other suit**.
### **Execution: Entry in the B-Threat Protector (♦️A)**
In this specific scenario, the required entry to the North hand is the **♦️A**, which also serves as the protector for the **B-threat**.
#### **The Play:**
1. **The Squeeze Lead:** South leads the **♠️A**.
2. **West's Dilemma:** West cannot discard the **♥️Q**, as that would expose their partner to a finesse in Hearts. Consequently, **West is forced to unguard Diamonds**.
3. **The Discards:** North discards the now-useless **♣️K**, which immediately puts **East** in a squeeze.
4. **The Result:** * If East unguards **Diamonds**, North’s **♦️6** becomes a winner.
* If East unguards **Hearts**, South’s **♥️J** becomes the winning trick.
#### **Golden Rules for Guard Squeeze:**
1. **Unblock** early to prepare for the eventual finesse!
2. **Cash down** until only **one protector** remains in the finesse threat suit!
