In Response To: Break Anchor Better With This One Weird Trick (Timothy Chow)

When these positions are placed side by side, it's clear that breaking anchor is more dangerous in Position 1. But how do you decide when the tipping point has been reached? I guess you amass positions like this one and gradually build your judgment. Note, by the way, that giving Blue a five-point board also makes a difference (not shown here).

There's a position sort of like this in What's Your Game Plan? I meant to look it up but forgot to.
