I have created a reference chart that suggests various actions for the big blind in response to a single raise. (This is a modification of an Excel spreadsheet written by Matt Mangham.)
To allow flexibility in the big blind's range for defense against a possible steal attempt, there are three "Call" categories: A (yellow), B (green), and C (blue). Adding only Category-A hands to the "Raise" hands will result in a fold-BB-to-steal of 60%; adding A and B: 50% fold; adding A, B, and C: 40% fold.
I am an amateur when it comes to blind defense, so there may be significant flaws with this arrangement. I would appreciate any opinions on which hands should be moved to which categories. Also, against which opponents and in which situations would you use A, A+B, or A+B+C to defend?
Thanks!
