Defense on LAG Tables: Strategy and Adjustments

Understanding 3-Bet Dynamics on a LAG Table

On tables with many Loose-Aggressive (LAG) players, the 3-bet frequency is significantly higher than normal. LAG players tend to raise with wide ranges and 3-bet more from late position or the small blind with a wider set of hands, aiming to use position and pressure to take down pots. Understanding a LAG's typical 3-bet range is the first step in defense.

Generally, a LAG's 3-bet range includes:

• Value hands: TT+, AQ+ (strong hands, but fewer in number)
• Semi-bluff hands: Suited connectors (e.g., 67s, 89s), small pairs (e.g., 55-99), AXs, etc.—hands with potential to hit strong draws on the flop
• Air: Some weak suited or offsuit connectors, even random hands (e.g., KJo, QTo), exploiting opponents' fold equity

When a LAG 3-bets frequently, you face 3-bets more often, so you need to adjust your defense strategy to avoid being exploited.

Core Principles of Defending Against 3-Bets

The core of defending against 3-bets is to balance your range while exploiting the LAG's wide range. Here are several key decision factors:

1. Position is King

• In position (you are in the big blind, LAG is on the button or small blind): You can defend with a wider range because you have positional advantage post-flop. Prefer calling, using post-flop reads and play.
• Out of position (you are in the small blind or early position): Tighten your defensive range, prioritizing 4-bet or fold. Calling leads to a disadvantaged position post-flop, making you vulnerable to continuation bets.

2. Stack Depth

• Deep stacks (150BB+) : Increase calling frequency because implied odds are higher, and you have more room to maneuver post-flop. For example, call with suited connectors or small-to-medium pairs to chase draws or sets.
• Medium stacks (80-120BB) : Focus more on range balance. Consider 4-betting to counter the LAG's aggression, especially when your hand has some blocking value (e.g., AQ, AJ).
• Short stacks (below 40BB) : Avoid calling 3-bets because post-flop maneuverability is limited, and the LAG will apply more pressure. Either shove with strong hands or fold directly.

3. Hand Selection

Hands for defending against 3-bets can be categorized into three types:

• Strong hands (TT+, AQ+) : Usually need to 4-bet or call (depending on position and opponent tendencies). Against a LAG's wide 3-bet, these hands have enough value, but be careful not to over-defend and avoid shoving in unfavorable spots.
• Medium hands (66-99, ATs, KQ) : Call or 4-bet. If the LAG's 3-bet range is very wide, you can 4-bet bluff with these hands, or call and play aggressively post-flop.
• Speculative hands (suited connectors, small pairs) : Only recommend calling when in position and with deep stacks. Fold when short-stacked or out of position.

4. 4-Bet Strategy Against LAGs

4-betting is an effective weapon against LAGs, but must be used carefully.

• Frequency : Against a frequent 3-bettor, you can increase your 4-bet frequency to 15-25% (of your defending range), but don't overdo it or you'll be countered.
• 4-bet range : Consists of value hands (QQ+, AK) and some bluff hands (e.g., A5s, A4s, which have blocking effects). Example: When a LAG 3-bets your EP raise from the button, you can 4-bet for value with KK+, and 4-bet bluff with A2s-A5s, blocking their AX hands.
• Sizing : Standard 4-bet size is 2.2-2.5 times the original 3-bet. With deeper stacks, you can size up slightly to apply pressure.

5. Post-Flop Strategy After Calling

If you choose to call a 3-bet, be proactive post-flop, especially when the flop is unfavorable for the LAG's wide range.

• Continuation bet : On the flop, even if you miss, consider betting (about 1/3 pot), representing that you hit a strong hand. LAGs may over-fold.
• Raise : When you have a draw or top pair, you can raise against the LAG's continuation bet, forcing them to fold weak hands.
• Bluff : On blank rivers, if your hand has no showdown value, try a river bluff, as the LAG's range contains many weak hands.

Exploitative Adjustments

Against a LAG, you can introduce exploitative adjustments:

• Increase 4-bet bluffs : If the LAG has a high fold rate to 4-bets in their 3-bet range, then 4-bet bluff with more blockers (e.g., AQo, KQo).
• Widen calling range : When the LAG's 3-bet range is extremely wide (e.g., 15%+), you can call with more medium-strength hands like ATs, KQ, 99, and exploit their over-aggression post-flop.
• Reduce folds : Unless out of position or short-stacked, don't easily fold to a LAG's 3-bet. Preserve your defending range to force the LAG to lower their 3-bet frequency.

Common Mistakes

• Overfolding : Many players overfold out of fear against a LAG's 3-bet, giving the LAG cheap profits.
• Calling too much with medium hands : Calling 3-bets out of position or with short stacks makes your hands difficult to play post-flop, leading to losses.
• Unbalanced 4-bet range : If you only 4-bet with strong hands, the LAG will quickly catch on and fold weak hands, causing you to win small pots and lose big ones.

Example Scenario

Scenario : 6-max cash game, blinds 1/2, effective stack 100BB. You raise to 6 from middle position with J♠ T♠. A LAG on the button 3-bets to 18.

Analysis: You open-raise from middle position, and the LAG 3-bets wide from the button. Do you have position? No, the button has position over middle position. Therefore, folding should be prioritized here, because JTs is not strong against the LAG's 3-bet range while out of position and with a medium stack depth. If you call, the LAG will continuation bet postflop, making it difficult to play. The correct play is to fold.

Better Hand Example: If you hold A♠ Q♠, you can 4-bet to 45-50, aiming to make the LAG fold his weak hands while having an ace blocker. If the LAG shoves, you decide whether to call based on the opponent's tendencies.

Summary

Facing a 3-bet from a LAG table, the core is the combination of position, stack depth, and hand selection. There is no fixed formula; constant adjustment is needed based on the opponent's 3-bet frequency, postflop tendencies, and table dynamics. Mastering the balance between 4-betting and calling, and leveraging postflop aggression, is key to maintaining profitability in high-aggression environments.
