Why is AJo Popular This Summer? Exploring the GTO Strategy of Calling a 3bet Preflop
Recently, a question on the Reddit poker subreddit (r/poker) sparked discussion among players: "Is there a solver indicating that calling a 3bet with AJo out of position (OOP) is GTO?" This short query highlights a hot topic in the current poker strategy community — AJo appears frequently in recent strategy discussions.
This article will analyze the rationale of calling a 3bet with AJo from the perspective of GTO solvers, incorporating positional factors and practical adjustments, and explain the reasons behind its "popularity."
Do Solvers Really Recommend Calling a 3bet with AJo?
Modern GTO solvers (e.g., PioSolver, MonkerSolver ) typically provide mixed strategies when simulating preflop confrontations. For common scenarios like BTN vs BB or CO vs BTN, solvers sometimes call a 3bet with AJo at a certain frequency, but the frequency is usually low and highly dependent on stack depth, position, and the opponent's 3bet size.
Generally, when out of position against a tight 3bet range, AJo is a marginal hand better suited for folding. This is because AJo has poor playability: it is often limited by high cards like A or J and gets dominated in multi-way pots or all-in postflop scenarios. However, when the opponent's 3bet range is wider and includes more bluffs, AJo's blocking effects (blocking strong hands like AA, AK, AQ) make it a decent defensive hand.
Why Has AJo Become a Topic This Summer?
The joke on social media that "AJo seems to be popular this summer" may stem from the following trends:
- Increased Use of Solvers: More players are using solvers to study preflop ranges, discovering that mixed strategies in certain scenarios include calling with AJo, and thus attempt to mimic them.
- Influence from High Stakes: Some high-stakes cash game players have started increasing their defensive frequency with AJo in small stack situations (e.g., below 100bb) or specific blind battles, triggering a learning wave.
- Strategy Layering: Against aggressive 3bettors, calling with AJo can protect the blind range while inducing subsequent bluffs.
Practical Advice: When to Call a 3bet with AJo?
- Position Advantage: If you are on the BTN or CO (not SB/BB) and have position facing a blind's 3bet, you can increase the calling frequency with AJo.
- Opponent Tendencies: If your opponent has a high 3bet frequency (greater than 10%) and a low postflop fold rate, AJo can be used for defense.
- Stack Depth: When deeper than 100bb, AJo's playability improves, offering opportunities to outdraw postflop; with shallow stacks (<40bb), it is better to fold directly or 4bet shove.
- Avoid Making It the Default: Even if solvers include a small mixed calling frequency, it should not become a default strategy. In most live or low-stakes games, opponents' 3bet ranges are stronger, making calling with AJo a -EV play long-term.
Summary
Calling a 3bet with AJo is not a standard GTO recommendation, but under specific conditions (wide opponent range, position, deep stacks) it can be part of a mixed strategy. The recent "popularity" more reflects players' enthusiasm for exploring solver strategies rather than a true high-frequency play. For most average players, folding AJo out of position remains the safer choice.
