Nactation Tutorial • Explanation of nacbracs • Nacbracs for cube actions

This one is in my RolloutSummary spreadsheet. Tim already has a copy, but in case you do not, drop me a line if you would like to be added to my distribution list. Be forewardned, the RolloutSummary uses Nactation and nacbracs to summarize a large number of early game rollouts.

I added the no-Jacoby GnuBg trunc today just to remind readers how good the neural nets are in version 1. In the overwhelming majority of cases, GnuBg matches XG almost exactly in these early game positions. That is true for both equity and ranking of plays.
