Stick put it this way (
BGO Msg. No. 160835):
The basic idea of O'Hagan's Law is that you usually have an initial double:- If you have 9 market losers
- Are doing alright on the other 27
- If you're within 6% of the opponent's true take point.
In a non-volatile position, you can wait to double until you reach the high end of the doubling window. When a position is volatile, however, and there are many market losers, you may want to double sooner. O'Hagan's Law gives you a rough quantitative guide to help decide just how much sooner.
BTW, O'Hagan's Law is more a guideline than a law. Depending on the position, for instance, you can lay off your bad rolls against some of your good ones. If you have 12 big market losers, but also have 3 rolls that swing big the other way, you can subtract the two to reach the 9 needed for a double.
Caveat emptor!
This is a guideline, not a rigid rule.
