The Calling Station

Calls with any pair and any draw. Get paid, don’t bluff.

The Calling Station calls too much and rarely raises or folds. They hate to fold any pair, call with draws whatever the price, and never bluff. Most players lose to them by trying to make them fold. You beat them by getting paid.

In short

Before the flop

The Station rarely raises first. They raise a short list of strong hands and limp a lot of the rest:

SeatRaisesLimps
UTG8% of hands42%
HJ and CO9%46%
BTN9%56%
SB9%66%
The Station's raise from any seat but under the gun: 122 combos. (Under the gun it's KQ instead of KJ+.)

That split tells you a lot:

The Station's limp from the button: 748 combos, 56% of hands.

If you raise their limp, they never re-raise. They call with the grid below: 66% of their under-the-gun limps and 77% of their button limps fold.

What the Station calls a raise of their limp with: 252 combos.

A 3-bet is the grid below. That's under 5% of hands, so believe it.

The Station's 3-bet: 34 combos. From the big blind it's JJ+ and AQ+ (56 combos).

If you 3-bet them, they 4-bet only the grid below, and call with almost everything else they raised. Only KJo folds: 10% of their raises from the later seats, nothing from under the gun.

The Station's 4-bet: 16 combos.

When they call your raise, their range is huge: 45% of hands from the big blind against a button open. But it has a ceiling: JJ+ and AQ+ 3-bet, so it holds no big pairs.

After the flop

The Station's habits are simple, and they're the same on every street:

Facing a bet, they:

Any pair, two pairCallCallCall
Any draw, even a gutshotCallCallCall
Ace-highCallCall on flop and turn with two overcardsFold

Everything elseFoldFoldFold

A raise from them is a set or better. Top pair and two pair just call. Any pair calls on every street, even a raise: top pair, second pair, bottom pair, a pocket pair under the board. Draws call on the flop and turn, and missed draws fold the river.

Once less than three pots are left behind, ace-high calls any bet. Too much in the pot to fold, in their eyes. That is the one thing the size of the pot changes: a 3-bet pot plays like a single-raised one.

K♥10♣4♦
The Station called your button open from the big blind. Here they bet 80 of 524 combos.

Those 80 are top pair, two pair and sets; the other 444 check. So a check means no top pair. A bet means top pair or better. A call mostly removes their air, and how much of it depends on your size:

K♥10♣4♦
After that check, 395 of 444 combos call a 1/3-pot bet. Only 208 call half pot or 2/3.

The small bet is called by every pair, straight draw, ace-high and backdoor flush draw; 49 fold. The half-pot or 2/3-pot bet is called by pairs and straight draws, and 236 fold.

On the turn and river the pairs keep calling, and the draws call until they miss. Say they called a 2/3-pot flop bet and a pot-size turn bet:

K♥10♣4♦7♠2♣
On this river 142 combos call another pot-size bet, and 48 missed draws fold.

The 142 are 126 pairs and the 16 combos of AJ, a missed gutshot that calls only because the pot is big next to their stack: 38.5 in the pot and 81 behind, two pots. The 48 that fold are QJ, Q9 and J9.

How to exploit them

in both− they have, you left out+ you included, they don’t have
The Station's range after checking K-T-4 and calling a 2/3-pot bet.

The read kept KQ, KJ, TT and 44, which would have bet, and left out the weaker tens, bottom pairs, gutshots (AJ, Q9, J9) and the open-ender QJ.

What this leak is worth. The Station is the villain who pays you most, and steadily. On Q-7-3-K-8, after calling your flop and turn bets (two-thirds pot and pot), 90 of the 102 combos that check the river call a pot-size bet, every one of them a pair.

What their bet sizes tell you

Nothing about the hand. A third of the pot on a dry board, half the pot otherwise, on every street, with top pair and with a flush alike. Raises are always three times your bet. The bet itself is the tell: top pair or better.
