40/40 'Short Game' analysis

[Shaun]

Short decided games analysis.

I am running some analysis of our short decided games from the 40/40 rating list.

Analysis is for games decided in 20 or fewer moves.

Analysis - 15 minutes per move (equivalent to 10 minutes on the standard CCRL machine).

I am using Crafty 21.5 for analysis as it can run from the command line off a usb key without intalling anything, a book of common moves is used to analysis save time.

for info here is the crafty.rc file I am using for analysis of whites moves (i.e. game won by black).

Code: Select all

hash 512m
hashp 128m
annotate BlackWin(clean).pgn w 1 -1 900 1

The book is from a database of GM games 2400 elo plus (no blitz etc), using the following parameters

Code: Select all

book create 2400Plus.pgn 40 5 50

output

Code: Select all

parsed 9003887 moves (236515 games).
found 0 errors during parsing.
discarded 0 moves (maxply=40).
discarded 4264201 moves (minplayed=5).
discarded 26693 moves (win/lose=50.0%).
book contains 83022 unique positions.
deepest book line was 40 plies.
longest cluster of moves was 20.
time used:    1:04 elapsed.

P.S. I would be interested in any other ways I could script the analysis from the command line that would allow me to use additional engines.

White win 1.

Hi Shaun! Thanks for doing this analysis! Can you already post any conclusion or summary (even for several games)? Are those games valid which means the losing engine made mistakes? Or was the opening clearly biased so the games should be removed?

[Shaun]

Kirill,

So far the 2 short wins for black do not look like book losses to me.

I am working through the 11 White wins within 20 moves.

White game 1.

Blacks move 9 analysis is still running (this has been running 24 hours now)

so after

9. Na4

Black(9): Nxe4 is behind Rybkas first choice at depth 21

The 2 common book moves Bd7 and Bb7 are not currently liked by Rybka so I am giving her more time.
