Strategic Guide

Sometimes, this spot just isn't that favorable.

BB vs BTN open (3-max)

This is probably the position where you’ll lose the most money in Spins. Let’s see how to limit the damage.

👀 Key Takeaways

1️⃣ Position is a big advantage for the BTN, so stay cautious with your calls.

2️⃣ Avoid bluff 3-bets. Recreational players call too often for them to be profitable.

3️⃣ Prefer value 3-bet shoves. They punish loose calls and maximize your EV.

4️⃣ Pay attention to open sizings. The bigger the raise, the stronger the hand likely is — tighten your range accordingly.

5️⃣ Don’t overcomplicate things. Keep it simple: call a good chunk of hands, shove the best ones, and fold the rest.


1. One of the positions where you’ll lose the most money

Even against recreational players, the BB vs BTN open spot is structurally tough. You’re forced to invest 1 bb every hand and play out of position against a generally solid range.

Theoretical winrates (GTO vs GTO) — i.e., when both players play perfectly — look like this:

Stack Size EV (bb)
20-25 bb -0.42
16-18 bb -0.47
12-14 bb -0.59
8-10 bb -0.73

➡️ Even when playing perfectly, you still lose money.

📊  Against recreational players, you’ll lose a bit less, but your goal won’t be to crush the position — it will be to minimize the damage.
That’s why we’re going to be careful — no matter who you’re up against.

2. Stay cautious, even against recreational players

We’ve already analyzed BTN open ranges in the following strategic guides: SB vs BTN open and BB vs BTN open + call, but here’s a quick refresher.

📊 What’s in the BTN open range?

Recreational players tend to open slightly less than GTO, but with a similar structure:

  • Pocket pairs (22+)
  • Most Ax
  • Broadways (KJo, QTo...)
  • Occasionally higher sizing with premiums (AA, KK...)
Left: GTO open range at 25 bb. Right: Recreational player open range.

Ranges are fairly similar, though the core of the recreational range tends to be slightly stronger.

❓ Why not defend everything?

Even against a recreational player, being out of position is a huge disadvantage.
Calling hands like Q2o, K3o, or T6o puts you in awkward, often losing spots postflop.

Exploitative Range – BB vs BTN open (18–25 bb)

✅ A good habit to develop

Use your tracker to check your BB/100 winrate for “borderline” hands — the ones you often hesitate to call or fold (e.g. K4o, J7o, J6o...).

→ Rule of thumb: for any hand with EV lower than -100bb/100, folding is better than calling.

📉   The reason is simple: if you had chosen to always fold these hands instead of calling, you could never lose more than 100bb/100, since you’d be losing exactly 1 blind per hand — that is, 100bb per 100 hands.

That means you’re losing more money trying to play the hand than you would just folding it every time.

Sometimes folding a marginal hand is just the smarter play.

⚠️ Important note on open sizings

Our ranges are designed to counter a standard 2 bb open from BTN.

However, recs often use non-standard sizings.

→ In most cases, their open sizing correlates with hand strength — the bigger the raise (2.5x, 3x, 4x+), the stronger their hand usually is.

🛡️   So, the bigger the BTN’s open sizing, the tighter your defense range should be. Especially since we can observe in practice that their c-bet frequency increases with the pot size.

Here are the average recreational open ranges by sizing (2x, 2–3x, 3x+):

Left: 2x • Middle: 2–3x • Right: 3x+.

You don’t need to study every range in detail — just note the general trend:The bigger the sizing, the stronger the range.

Recreational players are basically telling you to be careful when they go big.

Note: That doesn’t mean you should fold everything vs a 3x open. There are still plenty of medium-strong hands in their range.

But when you're unsure about whether to call or fold a marginal combo, remember:

There’s no clear line.

Between a clear call (like A8s) and an obvious fold (like 72o), there’s a wide neutral EV zone.

➡️ There’s no need to beat yourself up over a marginal call or fold that might have cost you some chips — there’s some leeway.

Notice how EV declines progressively as hand strength drops.

3. Shove your good hands and forget the bluffs

❓ Why avoid 3-bet bluffs?

Recreational players tend to call too much after they’ve invested preflop.

So your bluffs will not get through as often as they should.

❌   Non-all-in 3-bet bluffs become ineffective, because they rely heavily on fold equity. Plus, they expose you to difficult postflop spots out of position.

✅ Why value 3-bet shoving works

A 3-bet shove directly exploits overly loose calls from recs.

It’s simple, efficient, and prevents tricky postflop spots out of position.

With your strong hands (AT+, 55+, KQo...), you’ll maximize EV by shoving rather than slowplaying or doing a non-all-in 3-bet.

Call rate of recreational players vs BB 3-bet shove:

Stack Size GTO 🤖 Recreationals 🐟
20-25 bb ~30% ~46%
16-18 bb ~40% ~70%
12-14 bb ~45% ~66%
8-10 bb ~67% ~88%

As you can see, they call way more than they should versus your shoves from the BB.
