In chapter 18 of Small Stakes Hold’em, the authors explain how and when to use overcalls—calling a bet after someone else has already called—to squeeze extra value out of loose, multiway river situations.
What an Overcall Really Means
An overcall happens when a player bets, one person calls, and you call after them. This is not the same as being the first caller. To justify an overcall, your hand must be stronger, because:
-
You must beat two hands, not just one.
-
The original bettor might be bluffing, but the first caller almost never is.
If your hand only beats a bluff, overcalling is a mistake.
Why Overcalls Matter in Small Stakes Games
Small stakes games go to the river with multiple players far more often than tougher games. Many players overcall with hands that have almost no chance to win. This creates “dead money” in the pot. If you choose your spots well, you can profit by encouraging those bad calls rather than chasing them away with a raise.
When You Should Try to Get Overcalls
Instead of raising a river bet with a strong hand, it is often better to just call when:
-
There are several players left to act behind you.
-
Those players are loose and will call with weak holdings.
-
Your hand is strong enough to beat most of what they can have.
-
The pot is not already enormous.
-
The bettor might have a very strong hand or might be bluffing.
In these cases, raising often gains little, while calling gives loose players a chance to put in extra money with worse hands.
Why Raising Can Be a Mistake
If the bettor is bluffing, he may fold to a raise, costing you value.
If the bettor is very strong, he will not fold anyway, so your raise only risks extra money.
Meanwhile, the loose players behind you—who might call one bet with second-best hands—will often fold if faced with a raise. By just calling, you keep them in and let them make costly mistakes.
Key Situations Where Overcalls Shine
Some hands are especially well-suited to this tactic:
-
One-card straights: You often tie or beat part of the field, but raising scares off the hands you beat while never folding the hands that tie or beat you.
-
Second-best flushes or similar near-nut hands: The bettor may have the nuts, and raising will not push him out. But weaker hands behind you may still call one bet if you do not raise.
In both cases, your best chance to earn extra money is to let others overcall.
The Big Picture
Raising on the river is not always the best way to extract value. In loose, multiway pots, calling can be more profitable because it invites weak players to make bad overcalls. Thinking carefully about who is behind you, how strong your hand is, and how your opponents behave will help you decide when a simple call is worth more than a raise.
