Neil's errors in OLM play

Posted By: Jason Lee

A question was raised in the last OLM match ending thread. The question was about how much time Neil Kazaross spends on the OLM, and what his error rates might be if he had unlimited time.

I sort of have an answer. Neil plays against the USBGF Members in the USBGF OLM. There are no time limits on Neil, and I know that he occasionally takes full advantage of that.

We're early on in the 4th 11 point match, and in the first three matches, Neil had PRs of 0.18, 0.39, and 0.33. Early on in the 4th match (just the second game), he's so far at 0.46.

As a matter of interest, I'm going to give you every single one of Neil's errors (according to XG, at least) in the USBGF OLM (at the XG threshold of 0.020) in three matches plus part of a fourth. The usual caveats apply as to whether or not these are really errors.

I hope this is clearly seen as proving Neil's knowledge and capability at backgammon, rather than anything negative. I'm posting this partly to show what might be interesting positions, and partly to point out HOW FEW OF THESE I'M POSTING! Also, all of these matches are public information to USBGF Members.

I will post the rollouts and what Neil actually played later.
