The 5 Preflop Mistakes Costing You the Most in Spin & Go

In Spin & Go tournaments, your edge lives or dies preflop. With starting stacks of 25 big blinds and blinds that rise fast, most pots are decided before a community card ever hits the board. That means every preflop mistake — no matter how small it feels in the moment — compounds across hundreds and thousands of games into a significant chip leak.

Here are the five preflop errors that cost Spin & Go players the most, and how to fix each one.

Mistake #1: Playing the Same Ranges Regardless of Stack Depth

This is the most expensive mistake in Spins, and it's shockingly common. A player learns a set of opening ranges and applies them at every stack depth, as if 25 big blinds and 12 big blinds are the same game. They're not. They're fundamentally different strategic situations.

At 25 BB, you have room to raise, get 3-bet, and fold. At 12 BB, a raise commits such a large portion of your stack that you're often better off shoving or folding. The hands that are profitable to open-raise at 25 BB can become losing plays at 15 BB because the risk-reward changes entirely.

The fix: Learn your ranges at specific stack depth breakpoints. At minimum, you need different strategies for 25 BB, 20 BB, 15 BB, 10 BB, and under 8 BB. Each of these zones has meaningfully different optimal play. This is exactly what tools like OneRange are built for — they organize ranges by stack depth so you always know the right play for your current situation.

Mistake #2: Open-Limping from the Small Blind

In cash games and multi-table tournaments, limping from the small blind can sometimes be part of a balanced strategy. In Spin & Go tournaments with short stacks, it's almost always a mistake.

When you limp from the small blind, you give the big blind a free look at the flop with their entire range. You invest chips without building a pot or putting pressure on your opponent. And because stacks are short, any postflop pot quickly becomes an all-in situation where you're out of position — the worst possible combination.

The problem compounds because limping invites the big blind to check behind with hands they would have folded to a raise. You're literally keeping their worst hands in the pot against you.

The fix: From the small blind in Spins, your default strategy should be to either raise or fold. At shorter stacks, it becomes shove or fold. There are very few stack depths and positions where limping is correct in three-handed play. Remove it from your default approach and you'll immediately plug one of the most common leaks.

Mistake #3: Calling Too Many Shoves from the Big Blind

When someone shoves all-in and you're in the big blind, there's a natural temptation to call. You've already invested a blind, the pot is offering you a price, and folding feels like giving up. But calling too many shoves is one of the fastest ways to hemorrhage chips in Spins.

The math of calling an all-in is unforgiving. You need a certain amount of equity against your opponent's shoving range to make a profitable call. Many hands that feel "good enough" — hands like K6 offsuit or Q8 suited — are actually losing calls against a reasonable shoving range at certain stack depths.

The emotional pull to call is strong. You're getting "a price." You're tired of folding. Your opponent has been shoving a lot and you want to fight back. But emotion doesn't change the math. A losing call is a losing call, no matter how justified it feels.

The fix: Learn your calling ranges against shoves at each stack depth. These ranges are tighter than most players expect. The key variable is your opponent's shoving range — the wider they shove, the wider you can call. But against a reasonable opponent, you need a stronger hand than you think to call profitably.

Mistake #4: Ignoring Position Entirely

In a three-handed Spin & Go, position is everything. The button acts last on every postflop street. The small blind is sandwiched. The big blind gets a discount but plays out of position. These aren't small differences — they fundamentally change which hands are profitable to play.

Yet many players treat all three positions the same. They open the same range from the button and from the small blind. They defend the same hands in the big blind whether the raise comes from the button or the small blind. This ignores one of the most basic and powerful concepts in poker.

How this leaks chips:

• Playing too tight from the button. This is the most profitable position at the table. If you're not opening wide from the button, you're leaving money on the table every single orbit.
• Playing too loose from the small blind. The SB is a tricky position. You have position on the BB but are out of position against the button. Playing too many hands here — especially with medium-strength holdings — gets you into difficult spots.
• Over-defending the big blind. Getting a discount on calls doesn't mean calling is always correct. The postflop positional disadvantage often outweighs the preflop discount, especially at shorter stacks.

The fix: Have distinct ranges for each position at each stack depth. Your button range should be significantly wider than your small blind range, which should be wider than your big blind range (when you're the one initiating action). This isn't complicated — it just requires knowing the correct ranges and applying them consistently.

Mistake #5: Not Adjusting Your 3-Bet/Shove Ranges

When an opponent opens with a raise, your response options include folding, calling, or re-raising (3-betting). At shorter stacks, that 3-bet often becomes an all-in shove. Many players either never 3-bet shove (too passive) or always do it with the same hands regardless of stack depth (too rigid).

The optimal 3-bet shove range changes dramatically based on several factors:

• Your stack depth. At 25 BB, a 3-bet isn't necessarily all-in — you can raise and fold. At 15 BB, a 3-bet is essentially a shove. At 10 BB, your only options are shove or fold.
• The opener's position. A button open is wider than a small blind open, which means you can 3-bet shove wider against it. Adjusting your reshove range based on who opened is critical.
• Your position. 3-bet shoving from the big blind against a button open is different from 3-bet shoving from the small blind against a button open. Each has its own correct range.

The fix: Learn the key reshove breakpoints. The transition from "3-bet and fold to a 4-bet" to "shove or fold" happens around 15-18 BB depending on the situation. Below that threshold, you need a clear shove-or-fold strategy that accounts for your position, the opener's position, and your stack depth. Above it, you can be more creative — but you still need to know which hands are profitable to 3-bet.

How These Mistakes Compound

None of these mistakes feels catastrophic in isolation. Limping one hand, calling one marginal shove, opening a bit too tight from the button — each error costs a fraction of a big blind. But Spins are high-volume games. You play hundreds of tournaments per week. Each hand-level mistake multiplies across every session.

A player who fixes all five of these leaks doesn't just improve marginally. They transform their results. The gap between a player making these mistakes and a player who isn't can easily be several buy-ins per hundred games. Over a month of play, that adds up to a meaningful difference in your bankroll.

The Common Thread

Look at these five mistakes again. They all share one root cause: not having a clear, position-specific, stack-depth-specific preflop framework. Every one of these errors goes away when you know exactly what to do in each spot.

You don't need to be a solver expert. You don't need to calculate equity on the fly. You just need access to simplified, correct ranges for every position and stack depth — and the discipline to follow them. That's the entire game in Spins: know the right play, execute it consistently, and let volume do the rest.
