Above is the XGR++ rollout of the original position, copied from BenF's post.

Below are two variants. In Variant 1, it is still right to escape, despite the option of "safely" counter-priming.

In Variant 2, White's prime is reduced by one point, and Blue should no longer use the opportunity to escape.

Nack
