Explanation of nacbracs

XG2 Rollout Is TCTC

In this rollout from last May, playing up, U = 24/23 24/18, fares pretty well. Although clearly in third place, it trails by less than 0.01 points of equity. By the Ballard/Weaver error scale, that’s a tie.

In addition, this is one of those rare occasions where a full rollout overturns the XGR++ eval.

If you have a rollout of this position that you would like to share, please send it may way. I’ll include it in my RolloutSummary spreadsheet and give you credit.

Thanks.

Mike
