Further proof that you must roll it out

This position proves why XGR++ can not be relied upon to be entirely accurate. This is a position where the difference in plays must be 0.
Even when you roll it out 1296 there is still a .001 difference in the plays, so even that is wrong. And if you use XGR+ it is a BLUNDER to make the second best play. (It gets even funnier, as XGR+'s play is 9/3 6/1!)
Now, my goal is not to criticize XG, but to simply remind everyone that:
a) use XGR++ over XGR+;
b) you need to roll things out to be more certain, and
c) even rollouts are not 100 percent.
