Overcall
Calling after someone else has already called, so the pot goes to showdown three or more ways.

- What it means
- An overcall against an all-in means you join a pot where one player has shoved and another has already called. You need to beat both of them, not just one.
- How it is calculated
- The price looks great because two stacks are in the middle, but your equity is split three ways. Call when equity against both ranges × final pot beats the cost of the call. The drill samples the three-way equity with the engine, using the first-in push/fold ranges for the shove and the call.
- Worked example
- At 12bb the cutoff shoves, the button calls and you are in the big blind. The pot is 26bb and it costs 10.875bb more, so you need 10.875 / 36.875 ≈ 29% equity. A hand with 45% against one of them can have only 25% against both.
- Why it matters
- The caller's range is strong, because they called knowing someone could be behind them. Overcalls need much stronger hands than calling a single shove, and players who miss that pay off both stacks.
