The reason I posted this is that it is important to know recurring positions.

For money this is a close double so AtS it won't be a proper double as the single point to get to 4 away is quite valuable in comparison to the next point.

Here's the AtS RO. This is am important position to understand. The leader's TP is quite low when he can't lose a G. I was shocked when White passed instantly.
