I apologize if this is the wrong spot, I'd appreciate any guidance and where I should post poker theory questions ♠ tied to this book specifically?
I'm looking at the two alpha examples on pages 82 and 83:
Example 1):
9 handed 12.5% ante;Action ♠ folds to hero in the SB with 72o and an overly tight player in BB. What's the alpha if we ♠ raise 2.5bb from the SB?
They proceed to show alpha as 2/(2+2.625)=0.43.
