ATS opening

In Response To: ATS opening (eXtreme Gammon)

I am curious how many RO got their results changed (just the move order) from 3-ply to 4-ply.

On 4-ply, only the top plays have been rolled (usually the top two, occasionally the top three or four). For money, nine of the opening rolls have been covered, and 115 replies (at last count).

The only opening roll overturned is 64 [P S1 R6] <206, [R=S P4] ^46. However, of note is 41 [S $8] <173, [S $22] ^25; and 54 [S D3] <67, [S D11] ^46.

For opening 32, Z hasn't been rolled out on 3-ply, but we have [S Z6 D8] ^46, which is narrower than the other bots: [S D18 Z17] ~75*44 and [S D7 Z13] /92.

Let me know if you find this information helpful; if so, I'll report some of the differences that have arisen from the (more extensive list of) replies.

You also asked about estimating AtS results from money rollouts. I agree with David's comments. Notwithstanding, I think it would be a nice option to make the main three AA (Artificial AtS) results displayable, as Snowie does: buttons marked 1-1, 1-2, 2-1 -- though if I had my way they'd be d, s and g :)

There are positions for which AA (artificial AtS) equities won't be of much use, but not many (at least not in the early game) will lead one wildly astray. Even using David's example, 53P-41...

Snowie .. m[S U33 $34], d[$=S U9], s[S U8 $21], g[S $5 U34]
GnuBG .. m[S $32 U?], d[$ S10 U24], s[S $1 U11], g[$ S4 U?]
XG 3-ply m[S $23 U30], d[$ S3 U17], s[$ S2 U11], g[S $2 U?]

... even there, Snowie's AA results aren't so bad.

Applying rollout results to AtS scores other than d, s and g is problematic, because you have cube action muddying the waters as well. Perhaps Rick Janowski would have some thoughts.

While I've got your eye, you might have missed my question (and David's before it) here.

Cheers,

Nack
