SB HU (Exploit)

End of the Small Blind position in Heads-up (SB HU)

This chapter is the continuation (and therefore the end) of Chapter 2 (Push vs Recreational Players).

In Chapter 2, your only options were All-in or Not All-in. Now, for the hands that don’t go all-in (Not All-in), you have three choices: Fold, Limp, or Min-raise (2 BB).

🎯 Against a recreational player, three key differences compared to GTO

1. Far fewer folds preflop

Recreational players tend to iso-raise (= raise) far too little against limps.

As a result, when you limp, you often see a flop for the same price.

Since you realize your equity more easily, even your weaker hands have incentive to limp rather than fold.

The passivity of recreational players allows you to realize your equity even with your weakest hands.

🗑️ That said, it’s still fine to fold the 4–5 worst combos (the very bottom trash hands), even with deep stacks. In the trainer, folding the very bottom of your range will still be counted as correct.

🤑 More profitable min-raises

Most recreational players defend poorly against min-raises. They fold too much and 3-bet too little. That makes min-raising more profitable.

You can even consider min-raising a lot more hands than our standard charts recommend.

Our charts suggest MR with the top of your range (up to A8o / K8o / Q8o / J8o…),but you can expand to hands that “play well postflop” such as 87o, 86o, 67o, etc.

As explained in the SB HU guide, as long as your opponent doesn’t adapt, you could theoretically MR almost 100% profitably.

The only issue: even a recreational player eventually notices if you’re abusing MR in HU. So, adapt: if the BB starts defending or 3-betting more, reduce your MR frequency.If nothing changes, keep exploiting it.

Don’t make the mistake of underestimating recreational players. Most of them will notice excessive min-raising and respond with more aggression.

⚖️ In the trainer, we’ll therefore accept more min-raises than in our standard exploitative charts. So, you have a choice:

  • either follow our Exploitative Charts and min-raise moderately,
  • or deviate and min-raise more hands.

Your goal is to develop a feel in-game for the right balance between MR and limp, depending on your opponent’s reaction.

🤏 Very few limp-traps (except pocket pairs)

Against recreational players, it’s your job to put money in the pot.

Since they iso-raise so rarely, limping strong hands to “trap” (hoping for a raise) often means leaving value on the table: the pot stays small, and you give free cards.

Relying on recreational players to fall into your traps will often disappoint you…

Except for pocket pairs (especially medium/strong ones) which can sometimes limp-trap when short, there should be very few limp-traps in your SB range.

Thanks to Chapter 2, you already know which hands to push directly (especially dominant Axo). For the other strong non-push hands, prefer min-raising over limping: you take the initiative and grow the pot without depending on your opponent.

For example, GTO (chart above) might sometimes limp-trap a strong hand like KQs.

But the Exploitative version of that chart ☝️ will always min-raise this hand and similar ones.

💥 Special case: playing vs an aggressive BB

Against an aggressive recreational player, be careful not to become too passive or overfold.

In GTO, the BB strategy includes many ISO (both shove and non all-in) — yet the SB GTO strategy still mixes Limp and Min-raise across a wide range.

Here, for example, is the GTO BB chart (20–25 BB deep) vs a SB limp: You’ll notice in red and pink a large number of ISO.

Therefore, the default plan vs an aggressive BB should be to move closer to GTO:

  • add limp-traps with your strong hands (AK, AQ, KQ, good pairs, etc.)
  • shift your medium/fragile hands from MR → Limp
  • widen your fold range slightly

💣 If the opponent is hyper-aggressive (much more than GTO BB), push this logic further: more traps, more selective MR (open mainly hands that handle 3-bets well), and a few more folds with weak offsuits or borderline connectors.

That way you protect your EV while capitalizing on their over-aggression.
