Required win rate
Basic Definition
The required win rate refers to the minimum win rate needed in poker to expect a profit by calling the current bet. Calculating this helps avoid losses in the long term and aids in making appropriate decisions.
Specific Situation
If your opponent bets $100 into a $100 pot, the win rate you need to call is "100 ÷ (100 + 100×2) = 33.3%".
On the flop with 

and a hand of 
, you have 8 outs for a straight draw, giving you an approximate 31.5% chance of winning (considering both the turn and river). If this win rate exceeds the required win rate, it is worth calling.
Important Information
When calculating the required win rate, pot odds serve as the standard. If the pot odds are favorable, the required win rate decreases, making a call advantageous.
The larger the opponent's bet size, the higher the required win rate, so it's important to carefully assess the risk and return. Especially when considering the possibility of a bluff, the required win rate may change.
Examples of Term Usage
"I folded because the opponent's bet was too large, and my winning odds didn't meet the required odds."
