Trailer needs 16% to take ATS. XG recubed me here so I needed to decide whether or not I had 16% wins. OTB, I tried to estimate each side's EPC. For White, I used 12.5 wasted pips for an EPC of 64.5 (it's actually 65.9) vs. 76 for Black (don't know what it actually is). Then I wanted to know what kind of a favorite the leader would be with these same EPC's if it was a pips vs. pips bearoff. So I subtracted 7 from each to get a pip count of 57.5 vs. 69. Kleinman's formula gives the 57.5 side just under 84% chances. I figured there would be a little less variance in the actual position than in the pips v pips position so that it was probably a close pass. It is a pass, and a little bigger than I thought.
