Another strange thing

In Response To: stronger RO gives expected result (362k trials) (Nack Ballard)

A super long 4 ply rollout settled down on different answers than the XG++ rollout. It is much more easy to see a misplay being made from the gammon saving player's side so if there is any misplays I was expecting the 4 ply RO to give higher equity. However the 4 ply RO gives lower equity to the gammon seeking player than the XG++ RO does. Compared to your 1.4863 for the XG++ the 4 ply rollout is giving 1.4788 and 1.4758.

It is possible that an XG++ play is wrong while the 4 ply play is correct. Does anyone want to search for differences in plays made by 4ply and XG++?
