Above is the XGR++ evaluation of Svilo's position.
The only way I found to make the choice close (without being more radical) is to extend White's prime.
In Variant 1 below, a spare from each of White's points is moved back to make her 9pt. That's still not quite enough to overturn the robust @ (anchor, bar/22 23/22).
Variant 2 is the same as Variant 1, except for a minor spare adjustment. That's enough to (barely) reverse the order of the best and second best play.
