Somebody needs a good pounding. Wait... It's Dann again.

Split from Opening performance of engines.

This is the set for which your list of best moves does not match the move in my computer analysis. 19 of the analysis records are less than 36 plies, so not much value in an opening move analysis. I plan to analyze each one until it has a depth of at least 37 and an analysis time of at least one hour.

I counted 34 positions with depth under 37 in your list, Dann. Below is a trimmed version, numbered so that anyone can contribute analysis without duplicating effort.

Recommended analysis conditions:
- multiPV=2
- depth 37 or higher; or at least an hour if d=37 is reached sooner

Hmm, given that Komodo takes upwards of 3X SF's time to reach d=37, it somehow doesn't seem to equate the depths between the two.

Hmm, given that Komodo takes upwards of 3X SF's time to reach d=37, it somehow doesn't seem to equate the depths between the two.

I think it is a function of the individual position.

I guess that there are other positions where SF takes 3 times as long.

Watching TCEC, it appears that SF and K reach about the same depths in about the same times (on average). SF used to be much faster to ply depth, but the switch to LazySMP changed it so that they usually take about the same time.

Houdini, on the other hand, takes much longer to get to the same depth.

[Dann Corbit]

I am also reanalyzing the positions that agree. That has moved some of the positions from the success pile to the failure pile.

There are currently 68 positions total for which I have a different answer than the bm list stated in the problem set.

My current list of problems with a different answer from the stated list (found in field c3):
