The BTN vs BB single raised pot spot is the most common scenario in 6-max poker and represents the fundamental case study of positional advantage. BTN opens a wide range (45-50% of hands) while BB defends widely (55-65%) due to favorable pot odds and partially invested pot. Postflop, BTN holds range advantage on most high-card boards but BB can hold advantage on middling card boards. This spot is extensively solved by software and serves as the foundation for studying how position and range interact across every possible board texture.
