In Response To: Othello quizzes revisited (Timothy Chow)

Do you know you used XG1 for these evals? I noticed immediately because with #1 I would have anchored up at the score. XG2 agrees w/me though the plays are still close enough. (difference of .017 on XGR++) XG2 anchors on all plies.

For 'Position #7 from 2003' you posted the cube decision instead of the checker play problem.

Pos #2 from 2005 is 21$-55P-54 and a huge next agreed.

Pos #9 from 2007 .. your XG1 analysis is way off from the rollout results and from XG2's XGR+ analysis.

Pos #10 from 2007 has 4/3* 4/2* as bad. I'm not sure how bad it should be but it's clearly not correct. If you compare both positions your checkers are all in the wrong place after 4/3* 4/2* whereas 11/9* 4/3* puts them more or less where you want them.

Pos #9 from 2008. I don't think anyone is getting this play right.
