RO ..etc etc etc

RO's with XGR+ will be extremely valuable for studying some endgame situations. Here the position is quite simple to play and XGR+ is only three times slower than 4 ply RO. Some of this is because a lot of plays are nearly forced and won't need to be put through the filters all the way up to XGR+.
But when rolling out a game from the start, using XGR+ will be at least several times slower than 4 ply rather than just 3 times.
Once I know that I have the release version of the new XG2 NN, I'll start a RO of the opening 21 to get an idea of how long it will take. (I expect a couple weeks at least, even on this supercomp). For the opening roll junkies, I really don't expect to RO anything more than 21 and 64 using XGR+ although perhaps if I decide to use more computer time or have reason to think it may show something new, a couple other opening rolls will get some time.
