A “calling station” is a player who calls often regardless of their hand strength. These fold-averse players are most commonly found in live and low stakes online games.
Calling stations are relatively easy to beat, but they can also be frustrating to play against if you catch a cold run of cards. In this article, we’ll discuss 3 adjustments you can make to crush calling stations and boost your win-rate.
These insanely profitable adjustments were tested by Ryan Fee when he played 10,000 hands at $0.25/$0.50 on America’s Card Room for a recent Upswing Poker module. Here is his graph before he realized the player pool was full of calling stations:
And here’s his graph after making the adjustments:
Implement these adjustments to improve your win-rate against calling stations.
1. Drastically reduce your bluffing frequency
This is perhaps an obvious adjustment to make, but it’s too important not to emphasize: Do very little bluffing versus calling stations. Many players learn this lesson the hard way, though it can be easily avoided.
Put simply, if you notice that an opponent is making absurdly wide calls, then bluffing them will probably be in vain.
Fee played a hand at the $0.25/$0.50 tables that illustrates this point:
Americas Cardroom, $0.25 / $0.50 6-Handed. $10.87 Effective Stacks.
Hero is dealt K♣ 9♦ in the big blind
UTG folds. MP raises to $1. CO folds. BTN folds. SB folds. Hero calls.
Flop ($2.25): 8♥ T♠ 7♠
Hero checks. MP checks.
Turn ($2.25): 5♣
Hero bets $2. MP calls.
River ($6.25): 2♥
Hero bets $7.87. MP calls and shows K♦ 7♦.
Theoretically this is a great overbet bluff spot for Fee. The board is heavily favors Fee’s range, he holds a blocker to the nut straight (J9) and he doesn’t block the missed spade flush draw.
But these reasons are basically irrelevant if his opponent still won’t fold third-pair. The silver lining is that he learned his opponent is a calling station, and so he could ease up on bluffing as a counter strategy.
Again, the broader lesson to be learned here is to pay close attention to how your opponents play, and in particular take note of what they show down with when they call. Gathering information is key for making certain adjustments against your opponents.
Of course, calling stations do fold sometimes, so mixing in the occasional bluff in a especially prime spots is fine. This has the added benefit of maintaining our image as a potential bluffer, which makes it more likely we get paid off when we’re value betting. (If we never bluff, then we are the ones who become easy to exploit.)

2. Go for razor-thin value as often as possible
One of the most effective adjustments to make against calling stations is to bet for value in spots that would be too thin against most players. If you’re paying attention, you’ll notice that thin-value spot arise quite often—take advantage!
Here’s a good example from Ryan, again at $0.25/$0.50:
Americas Cardroom $0.25 / $0.50 6-Handed. $22.77 Effective Stacks.
Hero is in the CO with J♦ J♣
UTG folds. Villain (MP) raises to $1. Hero raises to $3. BTN folds. SB folds. BB folds. MP calls.
Flop ($6.75): 2♠ 5♥ 6♣
Villain checks. Hero bets $2.14. Villain calls.
Turn ($11.03): 6♦
Villain checks. Hero checks.
River ($11.03): 5♦
Villain bets $3.49. Hero raises to $17.63. Villain calls and mucks A♠ Q♦.
This hand demonstrates why you should think twice before making an “easy call” (or “easy check”) versus a calling station.
On the river, a conservative player might just call Villain’s bet fearing that a raise will only get called by better. However, Fee suspects more value to be had considering Villain’s range:
- Villain will rarely have 6-x or 5-x since he called a 3-bet pre-flop
- With hands as strong as QQ–AA, Villain would likely have been shoved all-in either pre-flop or on the flop
- Villain’s range is mostly hands with some showdown value, like Ace-high or 77-TT
Combine these range considerations with a player pool that’s practically allergic to folding, and you’ve got a recipe for a razor-thin value raise that will be called by worse often.
3. Size Up On Your Bets
Calling stations tend to have inelastic calling ranges. This means that in many spots they will call a bet regardless of how big or small it is.
We can exploit this tendency by using larger sizes with our value bets. Savvy players would pick up on sizing tells like this over time, but weaker players will rarely give it a second thought.
This final hand demonstrates how important it is to go for max value when it’s there for the taking:
Americas Cardroom $0.25 / $0.50 5-Handed. $50 Effective Stacks.
Hero is in the BB with A♥ A♠
MP folds. CO folds. BTN folds. Villain (SB) raises to $1.50. Hero raises to $4.50. Villain calls.
Flop ($9): 8♦ T♣ J♦
Villain checks. Hero checks.
Turn ($9): 6♠
Villain checks. Hero bets $7. SB calls.
River ($23): 4♣
Villain checks. Hero bets $38.50. Villain calls and mucks Q♦ T♦.
Once Villain checks for a second time on the turn, and then flats our delayed c-bet, we can heavily discount two-pair+ from his range. Given how connected the board is, we’d expect those hands to be played as leads or check-raises on the turn.
When the river bricks, we are confident we have the best hand and so we size up to exploit Villain’s tendency to over-call. The fact that the opponent calls almost a 2x pot bet on the river with second-pair, despite blocking our most likely bluffs, is proof of just how punishable calling stations are.
There’s also something to be said for the polarized nature of larger bet sizes. When an overbet is used, we are signaling to our opponent that we have either a very strong hand or complete air. As a result, players will still call down with marginal bluff-catchers.
Since we are going to be value-heavy versus calling stations, using larger bet sizes in polarized situations will be very effective.
To recap, make these adjustments to crush calling stations:
- Tone down your bluffing frequency
- Go for thin value as often as possible
- Use large bet sizes with strong hands to exploit their tendency to over-call
