Calling Station

Also known as: station, calling-station, stationy

A player who calls far too often and folds far too rarely — they pay off value but can't be bluffed.

A calling station is the passive species of fish: they call bets they should fold, chase draws without the pot odds to justify it, and almost never raise. Their leak is folding too little, which means their range stays wide and weak all the way to showdown.

The exploit is the most lucrative and most counterintuitive in poker: stop bluffing and value-bet relentlessly. Against someone who calls a river bet with bottom pair or ace-high, you can bet thin value bets that would be reckless against a reg, and you should size bigger because they call regardless. Conversely, firing three barrels as a bluff into a station is lighting money on fire — they were always calling.

This is textbook exploitative play: deviate hard from balanced frequencies because the opponent isn't punishing the imbalance. Tag stations in your player notes immediately — "never folds" is one of the most profitable reads you can hold, and it changes your bluff frequency to roughly zero and your thin-value frequency way up.
