Just a guess of me what a "2-liberty local rule" might look like:
"If a string has at most / exactly 2 liberties, then first consider as next move a play on an intersection adjacent to the string or adjacent to one of its adjacent strings that have at most 2 liberties themselves."
"If two strings, of which neither is a basic nakade string shape, share the same 2 liberties and do not have any other, then first do not consider a play on either."
Is this roughly something you might be using? (You do not need to reveal your secrets. I just would like to understand roughly what you mean by the concept "2-liberty local rule".)
