Reshove vs 3bet: Detailed Explanation of Preflop All-in Rebluff Strategy

What is Reshove?

Reshove refers to a all-in (4-bet shove) made by the original raiser or cold caller in a pot where there has already been a raise and a 3-bet. It's a preflop aggressive play used to counter an opponent's 3-bet, forcing them to fold or face a tough calling decision.

Why Reshove?

1. Leverage and Fold Equity

An opponent’s 3-bet range typically includes value hands and bluffs. Reshoving takes away their initiative and forces them to decide whether to risk their entire stack preflop. If they fold often enough, even a weak reshove can be profitable in the long run.

2. Avoid Passively Calling 3-bets

Calling a 3-bet with a weak hand often leads to difficult postflop situations, especially out of position. Reshoving simplifies the decision and ends the pot in one move.

3. Balance Your Value Range

Pure value hands (like AA, KK) also need reshoves to prevent opponents from realizing their equity. Mixing in some bluffs makes you harder to exploit.

Key Factors in Reshoving

Stack Depth

• Effective stacks < 40BB: Reshoving is very common because the 3-bet pot is large relative to stacks, making the shove a strong threat.
• 40-80BB: Still viable, but requires a tighter range since your equity when called may be insufficient.
• > 80BB: Generally not advisable with weak hands due to the high risk; instead, reshove only with very strong hands or call with medium hands.

Position

• Button vs Blinds: The button has positional advantage, making opponents (in the blinds) more hesitant to call a reshove since they'll be out of position postflop.
• Blinds vs Button: A reshove from the blinds typically represents a stronger range because it needs to counter the button's open raise and possible 3-bet.

Opponent's 3-bet Tendencies

• If an opponent's 3-bet range contains many bluffs (e.g., small suited connectors, AXs), your reshove can force folds.
• If an opponent's 3-bet range is very tight (e.g., only QQ+, AK), avoid reshoving weak hands as they will be called frequently.

How to Construct a Reshove Range

Example: 30BB effective, button opens 2.5BB, small blind 3-bets to 6.5BB

• Value reshove: TT+, AQ+ (adjust based on opponent tendencies). These hands have good equity against most 3-bet ranges and can handle a call.
• Bluff reshove: A5s-A2s, suited connectors like 56s-89s (choose hands with equity that block AA/AK). Note that bluff frequency depends on opponent's fold rate.

Typical range example (30BB, button vs SB 3-bet):

• Value: TT+, AQ+, AJs, KQs
• Bluff: A2s-A5s, 65s-87s, occasionally 59s (very few)

Math Validation

Calculate the fold equity needed to break even on a reshove. Assume your shove is 30BB, and when called your average equity is 40%:

• When opponent folds, you win (3-bet pot + open) = 6.5+2.5+0.5 = 9.5BB (blinds dead money)
• When called, your EV = 40% × (60BB total pot) - 30BB (your shove) = -6BB
• Let fold rate = x, then EV = x9.5 + (1-x)(-6) = 0 => x ≈ 38.7%

That means if opponent folds more than 39%, any hand reshove is +EV, but in practice you must adjust based on equity.

Practical Considerations

ICM Impact

In tournaments, near the money bubble, ICM pressure makes reshoving more profitable (opponents become more timid). However, also consider your own stack size — short stacks are more dangerous to reshove against because opponents can bust you if they call.

Responding to 4-bet All-ins

When an opponent responds to your reshove with a 4-bet all-in, you need to recalculate your calling range. Typically, you can only call with your original value reshove hands and fold the bluff portion.

Avoid Over-Bluffing

If you reshove too frequently under constant pressure, opponents will adjust and call more often. Use a mixed strategy and adjust dynamically based on opponent history.

Summary

Reshoving is an efficient counterattack in your preflop arsenal, but it requires careful consideration of stack depth, position, and opponent tendencies. Keep the math in mind, build balanced ranges, and refine your approach through practice.
