93o vs 86o Preflop Strategy and Win Rate Analysis at 40BB Depth

Definition and Basic Concepts

In Texas Hold'em, 93o and 86o represent the starting hands "9-3 off-suit" and "8-6 off-suit" respectively. The letter "o" stands for off-suit. Both hands are typical trash hands, and should be folded in almost all positions. However, under specific stack depths and opponent weaknesses, some players may occasionally consider playing them in the blinds or in stealing scenarios. This article assumes a stack depth of 40BB (approximately 40 big blinds) and explores preflop strategy.

Win Rate Comparison

Based on Texas Hold'em probability calculations, in a preflop all-in comparison (all flops random), 93o vs 86o has a win rate of about 53% vs 47%, leading by about 6 percentage points. However, actual preflop decisions are far from a simple comparison of hand strength, because both hands rarely go all-in preflop. The more common scenario is: a player holding 93o or 86o raises or calls preflop, then continues postflop based on the board. Since both hands are extremely weak, it is very difficult to make a strong hand postflop, so the expected value of putting chips in preflop is negative, unless there are very special compensating conditions.

General Principles of Preflop Strategy

At 40BB depth, preflop strategy follows a balance between GTO (Game Theory Optimal) and exploitative adjustments. For 93o and 86o, GTO strategy requires folding in the vast majority of cases. However, the following situations may be exceptions:

• Small Blind vs Big Blind: When the small blind faces an unraised big blind, the small blind only needs to complete 1BB to see the flop, getting excellent pot odds (about 3:1). In this case, if the small blind believes the big blind will not be aggressive, he may consider seeing the flop cheaply with 93o or 86o. But note that even postflop, these hands are very difficult to profit from, and in the long run they are still -EV.

• Big Blind facing a Small Blind steal: If the small blind raises to 2.5-3BB, the big blind must pay 1.5-2BB to see the flop, getting lower pot odds. In GTO strategy, the big blind defends with about 30-40% of hands, but 86o and 93o are usually not in the defense range because they lack playability. 86o, due to its connectedness, may be slightly better than 93o, but it is still marginal.

• CO/BTN steal: When it folds to the HJ or earlier positions, you should generally not actively raise with 93o/86o; but on the button when no one has entered the pot, facing tight small/big blinds, some aggressive players might steal with these hands, but the overall risk is high, and folding is recommended.

• Short stack scenarios: If the stack drops below 10BB, the jam range widens dramatically. But at 40BB depth, jamming with 93o or 86o is almost certainly a fish play.

Practical Examples

Example 1: Middle position folds, button holds 93o. Pot is 1.5BB (blinds + antes). Button raises to 2.5BB. Small blind folds, big blind calls. Flop: K♠9♦2♣. Big blind checks. Button hits top pair of 9s, but with a weak kicker and no draw. Betting about half pot can represent Kx or an overpair, but if raised, it becomes a difficult spot. This board actually favors the big blind's defense range, as the big blind has many Kx combos. In the long run, raising from the button with 93o is -EV, especially against aware opponents.

Example 2: Small blind, all earlier positions fold. Small blind holds 86o, pot is 2BB (small and big blinds). Small blind completes to 1BB, big blind does not raise (assuming the big blind is passive). Flop: 8♥7♠2♣. Small blind hits top pair with a straight draw (6789). He can value bet or check-raise. But this scenario is idealized; in reality, if the big blind raised preflop, the small blind would fold directly. And even hitting top pair, it is difficult to get paid by worse hands.

Typical Statistics: In a simulation of 1 million hands, 93o lost an average of about -30BB/100 hands (with high rake), and 86o lost about -25BB/100 hands. Therefore, from a long-term statistical perspective, both hands are clearly losing hands.

Common Misconceptions

1. Misconception: 93o is a suited hand (the "o" indicates off-suit) – Many beginners mistakenly think "o" means suited, but it is the opposite.

2. Misconception: The connected hand 86o has great postflop potential – 86o is indeed connected, but with small gaps, it is easier to make a straight; however, the probability of making a straight is low (about 5% for an open-ended straight draw on the flop), and it has no flush potential, making it difficult to play postflop. If you want to play trash hands, it is recommended to choose 54s, 65s, etc., which have flush potential and are connected.

3. Misconception: 40BB is deep, so you can play more hands – In fact, 40BB is medium depth, and trash hands should still be folded. Only in very deep stacks (>100BB) and against very weak opponents might you occasionally enter the pot with a few speculative hands in position, but 93o and 86o are still in the folding range.

4. Misconception: Which has a higher win rate, 93o or 86o? – Many think 86o is better because it is connected, but in a showdown, 93o has a larger pair, so it wins slightly more often. However, both are terrible hands, so there is no need to dwell on it.

Summary

For 93o and 86o at 40BB stack depth, the preflop strategy should be: fold in almost all situations. If in the small blind facing an unraised pot, you may consider completing at a very low frequency to see the flop, but mathematically it is still -EV. If stealing from the button, it is better to use hands with flush potential or connectedness instead. Remember, long-term poker profit comes from positive expected value decisions, and in the vast majority of scenarios, playing these trash hands is simply giving money to your opponents.
