astonishing that XG doesn't see it with 3-ply becausee the Anti-joker is not beyond the horizon.
I should say that this was XG 3-ply with a normal move filter, and 23/17 doesn't make it all the way through the move filter. If you manually force an XG 3-ply evaluation of both of the top two candidate plays, then 23/17 comes out on top.
