Before the flop you have three buttons: fold, call, raise.
The 3-bet post is about whether you press the rightmost one often enough. This post is about the middle one — the button you press without thinking and without counting.
It is far too easy to press. Somebody opens, you look down at KJs, folding feels like a waste, and raising means working out what you do when they 3-bet. The middle button neatly removes both problems.
But what it removes is the thinking, not the cost. Folding costs nothing at all; calling means matching their raise in full — you have paid, and you still have not decided anything. You think you bought the right to see a flop. What you bought is a pot with no initiative and usually no position, containing a player who acts before you with a stronger range than yours.
What is this number for? One sentence: it is your should-have-folded counter. This post covers what it costs, where the 5% line comes from, how to get yourself back under it, and how large a sample it takes before it counts. Read VPIP and 3-bet first if you have not.
Which of Your Calls It Counts
“Cold” means you have not voluntarily put a chip in this round.
Calling a raise from the big blind does not count — your blind is already on the table and you are only topping up the difference. Calling a cutoff open from the button does count: you start from zero and put the whole raise in cold, all at once.
The numerator is “you called”. The denominator is “you had the chance to call”. Four conditions have to hold at once, and they are the ones RushCraft actually applies when parsing hand histories:
You face exactly one raise, that raise was not yours, you have not voluntarily put money in this round, and you are not in the big blind.
So it only accumulates in four seats: MP, CO, BTN and SB. From UTG there is nobody in front of you to call; limping and then calling does not count (that is a limp-call, a different illness); calling after two raises does not count either (that is a different number).
Excluding the big blind entirely is deliberate, because it is a fundamentally different thing: your money is already in, the price difference is the smallest at the table, your position is fixed and the worst there is, and nobody behind you can squeeze. Averaging it in gives you a number that is wrong about both. Big blind defence belongs to fold BB to steal instead (target 55% or below, and only for the part that faces a late-position steal; facing an early-position open is currently not captured by any statistic, so you have to look at the hands yourself).
You Paid, and What You Bought Is Three Disadvantages
The difference between calling and 3-betting is not how much money goes in, it is who gets to define the pot — the 3-bet post covers that. A cold call carries three costs on top of an ordinary call, and they only apply while the call is cold.
First, your range is capped from the outset.
Your genuinely good hands went into 3-bets, so the ceiling of a cold-calling range is somewhere around JJ and AQ — no aces, no kings, no AK. Your opponent does not need to be a genius to know this. So when the flop comes ace-high or king-high, he can keep betting in complete comfort, because the strongest hands you could have simply do not exist.
A capped range can only defend after the flop, never counter-attack. This is the most expensive cost of a cold call, and the hardest one to notice.
Second, you invited the players behind you in.
Your call makes the pot bigger, which makes the price better for everyone behind. The button who would have folded T9s can now call, because of the money you added. You spent money improving somebody else’s pot odds — and now you play a flop against two opponents, from the middle seat.
There is a more direct version of this: the squeeze. An opener, you, and three or four players yet to act is the single best spot at the table for a squeeze, and you are the person who made squeezing profitable. When you get squeezed, folding is very nearly your only option (your range is capped and cannot take it), and the money you called with is gone.
Third, the price is worse than you think.
In the big blind, calling a 3bb open costs you 2bb more to see the flop. Here it costs you 3bb. Same hand, same flop, 50% higher cost. A lot of players build their calling habits in the big blind and then carry them, unchanged, into every other seat — this is the most common source of a high cold call, more common than simply liking to play hands.
The Target: 5% or Below, With No Floor
RushCraft’s target for cold call:
5% or below. Past 5% is a warning; past 6% it is flagged as a serious leak.
Start with the thing that is not written there: this number has no lower bound.
Every other statistic on the site is an interval, where too low and too high are both illnesses — VPIP at 18-25%, 3-bet at 8-12%, ATS with a band per position. Cold call is not like that: a player who never cold calls, who only ever chooses between 3-betting and folding, is not flagged for anything. He may give up a little marginal value, but he is not bleeding. Calling is not an action worth a frequency; it is an exception that is profitable under specific conditions — which is why this line only runs in one direction.
Note in passing that 5% and 6% are a single percentage point apart: the buffer between healthy and hazardous is thinner here than it is for 3-bet.
Which hands you are actually meant to call with
RushCraft’s cold-call drill (the “practise cold calling” button on the diagnostic card) puts you in the spot of facing one open, choosing between folding, calling and 3-betting. It checks the 3-bet range first, so a hand appearing in both tables is scored as a 3-bet, and only then does the calling list apply. That list splits four ways by seat:
| Your position | Default cold-calling list | Share of all starting hands |
|---|---|---|
| BTN | 22-JJ, ATs, AJs, KTs, KJs, QTs, QJs, JTs, T9s, 98s, 87s, 76s, 65s, AQo, KQo | 10.0% |
| CO | 22-TT, ATs, AJs, KTs, KJs, QTs, QJs, JTs, T9s, 98s, AQo | 7.7% |
| MP | 22-99, ATs, AJs, KJs, QJs, JTs, T9s, AQo | 6.3% |
| SB | 22-TT, ATs, AJs, KJs, QJs, JTs | 5.6% |
Two things there are worth a look. The more position you have the wider it goes, by nearly a factor of two: the button list contains hands like 76s and 65s that are pure potential, and the small blind has none of them — what position decides is not how much you call, it is whether you are allowed to call with hands that are not strong enough. And the SB row is narrowest not because the small blind gets bad cards: it is the only one of the four seats that has no position and still has players left to act, so it takes both disadvantages at once. A small-blind cold call should nearly always collapse into a 3-bet or a fold.
The third thing needs its own section: play the whole list and you go past the target band.
A hand being on the list does not make this hand a call
The right-hand column above is what share of all starting hands those lists cover. Call every time you are dealt one of them and your cold call lands around 7% — the button group on its own is close to 10%.
The line is 5%. Play the list in full and your own diagnosis flags you as high.
One hand makes the point fastest. You are on the button, the cutoff opens, you have 76s — a hand on the list. But at this table today, the man in the small blind re-raises the moment he sees anybody call. This hand is a fold, and the list will never tell you that.
Because the list only knows two things: where you are sitting and what you were dealt. It cannot see who is behind you, whether your opponent pays off after the flop, or how many chips you have left. Get any one of those three wrong and a hand on the list becomes a hand to fold.
So: the list says which hands are eligible to be considered a call. The 5% is how often you actually called. Getting from 10% down to 5% is a halving, and what closes that gap is what is actually happening at this table today. The five conditions in the next section are how you cut it.
(Practice mode’s 3-bet ranges are currently a first-pass approximation, reusing the table organised by the opener’s position; the preflop range charts draw them out square by square.)
When a Cold Call Is Not Laziness
Three sections on what it costs. But the line is not zero, which means there are times when it is right. Five conditions: the more of them hold, the more this is a call. With only one or two, go back to 3-betting or folding.
One: you have position, and there are not many players left behind you.
On the button facing a cutoff open, only two blinds are left to act. In middle position facing an UTG open, there are four players behind. The same KJs is a call in the first case and a fold in the second. The hand did not get weaker; every extra player still to act is one more player who can 3-bet you out of the pot — and if they merely call instead, you have more opponents to handle after the flop.
Two: your hand is the kind that lets go when it misses, not the kind that gets stuck halfway there.
This is about hand type, not hand strength:
- Small pairs and suited connectors: easy to recognise when they make a set or a flush, and easy to release when they do not. They run on implied odds — the full arithmetic is in how to work out pot odds
- Big offsuit hands like AJo and KQo: when they make top pair you cannot tell whether you are ahead or outkicked, and there is no second way to win. This is where cold calling loses the most money; these hands belong in a 3-bet or a fold
Three: the stacks are deep enough.
Set-mining with a small pair hits about one time in eight, so the pot you win back has to be big enough to justify it. With forty big blinds behind, the “hit it and win a fortune” story never gets told — with no implied odds, cold calling a small pair is just throwing a chip in the water every time.
Four: your opponent will not let go just because you 3-bet.
A 3-bet earns most of its money in the instant the other player folds. Against the kind of player who calls with anything he liked enough to play, and calls your 3-bet too, that income drops to zero — and 3-betting a medium hand into him just builds a big pot as a gift. Against that player, calling is correct: you get a cheap look at a flop, and when you hit he pays.
Five: the opener’s range is tight.
An UTG open means his range was strong to begin with. Re-raise with TT and you run into a bigger pair a good share of the time, and he is not folding — against a tight opening range, the fold equity and the hand-strength edge in a 3-bet disappear together. Calling to see a flop is reasonable here.
Turned around, those five conditions are a self-check. Before your next cold call, count how many of them hold. If you cannot count one, that was not a decision. That was laziness.
Reading Opponents: What a High Cold Caller Is
Everything so far has been your own number. Flipped around, a high cold call on the player across the table is one of the most welcome signals you can get.
Cold calling is the largest component of the gap between VPIP and PFR. Take a player with VPIP 30 and PFR 12: how does the money in those 18 percentage points get into the pot? Mostly by calling — limping, and cold calling. That gap is not an abstract personality sketch. It has a specific source.
When you see a high cold caller, three things follow:
| What he does | How you change |
|---|---|
| He enters with a pile of marginal hands, so his range is wide and capped | You can open a little wider, because he will call with worse than you |
| Once he calls he struggles to let go after the flop | Cut the bluffs and size your value bets up. Bluffing someone who does not fold is a pure loss |
| He cold calls in front of you with players still to act | This is the ideal squeeze spot. The opener is wide, the caller is capped, and neither can stand a big re-raise |
That last row is worth remembering: somebody else’s cold call is your opportunity. The second section said a cold call invites people in to squeeze you. Here you are the one being invited.
Sample Size: 50 Opportunities Resolve to Two Percentage Points
RushCraft’s rule for this number: under 50 cold-call opportunities, the card answers “not enough data” and says nothing else.
First, how fast they accumulate. The conditions are slightly stricter than 3-bet’s (you have to be in one of MP, CO, BTN or SB, facing exactly one raise), which works out at roughly 20 opportunities per 100 hands. So 50 opportunities is about 250 hands — a low threshold, as thresholds go.
But a low threshold does not make the number accurate. If your true cold call is 5%:
| Opportunities | Roughly how many hands | Observed number lands at | What that interval is good for |
|---|---|---|---|
| 50 | ~250 | 0% – 11% | Catching only the outrageous |
| 200 | ~1,000 | 2% – 8% | Obvious excess becomes visible |
| 500 | ~2,500 | 3% – 7% | You can start saying high or not high |
| 2,000 | ~10,000 | 4% – 6% | Only now is fine-tuning meaningful |
(Normal approximation of the 95% interval; the orders of magnitude are right.)
The first row is the point, and there is a blunter way to say it: at 50 opportunities the resolution is two percentage points — one extra call moves the number by 2%. Meanwhile the top of the target band is 5% and the serious-leak line is 6%, one point apart. On a 50-opportunity sample you cannot tell which side of the line you are on, and a single hand can push you from “normal” to “serious leak”.
So why set the threshold at 50? Because the illness this number is really hunting is not “5.4 or 4.8”, it is the player at 15% or 20%. That level is unmistakable at 50 opportunities, and how wide the interval is makes no difference to the conclusion.
The right way to use cold call is therefore bracketing, not tuning:
- 50 to 200 opportunities: confirm whether you are abusing it. A double-digit number is a conclusion already; no more data required
- Around 500: put yourself in the normal or high bracket, then cut using the five conditions above
- Past ten thousand hands: only now does “4.5 or 5.5” apply — and frankly that question is not worth much, because this number has no floor and going down is always safe
When the card flags you as high it gives you two buttons: one pulls up every hand you cold called (actually looking at those hands is far more useful than looking at a percentage), the other opens practice mode. The one to press after you see the number is the first — your cold calls will mostly cluster in two or three situations, and ten hands is enough to see the pattern.
If You Play Rush & Cash
On fast-fold tables, folding moves you to a new table, and that affects cold call more than any other statistic — in the direction of tightening.
The reason is in those five conditions: you cannot verify the fourth or the fifth. “This opponent will not let go to a 3-bet” and “this player’s opening range is tight” both require a read, and on a fast-fold table you never play ten hands against the same person, so no read ever accumulates. A condition you cannot verify is a condition you cannot assume, so cold calling on fast-fold tables should be narrower than at a fixed table, with the marginal hands going out to the 3-bet and fold sides.
There is an upside the other way: the opportunities accumulate quickly. At about 20 per 100 hands, fast-fold speed reaches the 500-opportunity mark from the previous section in a few evenings. The way to do it is to export your hand history from PokerCraft first (six steps, see downloading your Natural8 hand history); import it into RushCraft and your cold-call rate, its distance from the target band and which hands are producing it are already computed.
Cold call comes down to one sentence: facing an open, how often you choose the button that decides nothing.
- The denominator: exactly one raise faced, no voluntary money in yet this round, and not the big blind. In practice it only accumulates in MP, CO, BTN and SB
- The thing that is missing: this line has a ceiling and no floor. Calling is not an action worth a frequency, and too little has never been an illness
- The three costs: a capped range, the players you invite in behind you (and the squeeze), and a price 50% worse than the big blind’s
- The gap between the list and the line: the lists come to 7-10%, the target is 5% or below. The list only knows where you sit and what you hold, not who is behind you, whether he pays off, or how deep you are — that part of the gap is what those three things cut away
- The five conditions: position, a hand type that can let go, deep enough stacks, an opponent who cannot be pushed off, a tight opener. Cannot count one, and it was laziness
- The sample: 50 opportunities resolve to two percentage points, enough only for the outrageous. Bracket, do not tune
Next time somebody opens in front of you and your hand is neither strong nor trash — do not reach for the middle button yet. Ask yourself whether you are making a decision, or postponing one.
Folding is free. Postponing is not.
