Preflop Range Library

Ready-made ranges for common spots. 24 hand-picked ranges: opens, defends, 3-bets, 4-bets, squeezes, push/fold. Pick your seat and what happened before you; any range loads into the equity calculator in one click.

Example filled in: under the gun, nobody has bet. Change anything.

Step 1: Where do you sit?

Each seat shows how many hands it opens; the gold-er the seat, the more. The big blind never opens: it already has a bet in.

Step 2: What happened before you?

Under the gun, nobody has betOpen 9.8%

Raise with these 22 hands and fold the rest: 130 of the 1,326 two-card hands you can be dealt, 9.8%.

From the worst seat, you only open hands that play well multi-way and against light 3-bets. Tighten further at lower stakes; loosen at very passive tables.

Why

5 players act after you, and any of them can wake up with a strong hand, so an early seat plays few hands. Under the gun opens 9.8%; the button, last to act after the flop, opens 40.0%.

Open (RFI): RFI means raise first in: nobody has bet, so you are the first to raise. Every square is a starting hand; a range is the group of them you play.

What the names mean

Open (RFI): RFI means raise first in: nobody has bet, so you are the first to raise.
BB defend: Defend means keep playing against a raise. From the big blind that is mostly a call.
SB defend: Defend means keep playing against a raise. From the small blind that is mostly a re-raise.
3-bet: A 3-bet is a re-raise: someone raised, and you raise again.
4-bet: A 4-bet raises a re-raise: you raised, someone re-raised, and you go again.
Iso-raise: An iso-raise is a raise after a player only called the big blind (a limp), to play them alone.
Squeeze: A squeeze is a re-raise after one player raised and another called.
Push (Nash): Push means all in. Nash means the solved heads-up answer, the same as the push/fold chart.
Call shove: A call shove is the big blind calling an all in from the small blind.

Where these ranges come from

Ranges are calibrated against modern 6-max theory. They're a starting point: adjust to your specific opponents and stake level. The opens, defends, 3-bets, 4-bets, iso-raises and squeezes assume 100 big blind cash-game stacks; the push and call-shove ranges are the solved heads-up answers at 10 to 20 big blinds, the same hands as the push/fold chart.

Widths count combinations: a pair is 6 of the 1,326 two-card hands, a suited hand 4, an offsuit hand 12, so a range of pairs is narrower than its count of squares suggests.

Why a curated library beats a range dump

Preflop ranges are everywhere: screenshots on forums, charts in training videos, grids in Discord servers. The problem isn't finding ranges; it's knowing which ones to trust and being able to do something with them. This library solves both: 24 hand-picked ranges covering every core preflop spot, each with notes on when it applies, and each loadable into the range equity calculator in one click so you can actually test it.

It's built for micro-stakes players building their first serious preflop game. The collection spans raise-first-in ranges for all five positions, big blind and small blind defense versus different openers, value and mixed 3-bet ranges, 4-bets, isolation raises against limpers, a squeeze range, and tournament push/fold ranges at 10-20bb.

How to use it

1.Filter by category or search by name (e.g. "BB defend" or "squeeze").
2.Open a range and read the 13×13 grid plus the usage notes below it.
3.Load it into the equity calculator to see how it performs against another range or on a specific board.
4.Memorize one range per week. Opens first, then defends: that order matches how often the spots occur.

What "curated" means here

Every range is a solver-informed baseline adjusted for how micro-stakes games actually play: slightly tighter cold-calls (rake punishes marginal calls at NL2-NL10), slightly more value-weighted 3-bets (people don't fold enough), and isolation ranges that assume limpers are weak. They agree with the preflop charts on the core and extend them to spots the charts don't cover. If you want the frequency-level detail behind any open or defend, Solver-lite shows the full mixed strategies for nine of these spots.

Frequently asked questions

Where do these ranges come from?›

They're curated from solver-derived baselines and established charts, then tuned for 6-max 100bb play at micro and low stakes. Each range card includes notes on when to tighten or widen it. They're deliberately opinionated: a library of 500 ranges helps nobody.

How do I load a range into the calculator?›

Click any range card and choose to open it in the range equity calculator. The full combo set transfers automatically, so you can immediately test it against another range or a specific board.

Are the ranges for cash games or tournaments?›

Both. The opens, defends, 3-bets, 4-bets, isolations, and squeezes assume 100bb cash-game stacks. The push/fold section covers 10-20bb tournament shoves and calls, where Nash charts take over from standard ranges.

Should I follow these ranges exactly?›

As a starting point, yes. A disciplined baseline beats improvisation at micro stakes. As you gather reads, deviate on purpose: tighten your calls against nits, widen your isolations against limpers. The notes on each range tell you which direction to bend.

Which ranges should a beginner learn first?›

The five opening ranges (UTG through SB), in that order. They cover the decision you face most often. Add the BB defense ranges next. The 3-bet, squeeze, and push/fold ranges matter, but only after opens and defends are automatic.
