The number of seconds is not comparable as the hardware is different but the number of ply taken by Bright on my system is much more than on Dann's system (17 ply vs 14 ply). I wonder what is causing the difference ... I used 256 MB of hash for Bright and one thread.

Bright's transcendence was short lived. Glaurung has consumed only one second:

The number of seconds is not comparable as the hardware is different but the number of ply taken by Bright on my system is much more than on Dann's system (17 ply vs 14 ply). I wonder what is causing the difference ... I used 256 MB of hash for Bright and one thread.

I used 1 GB ram and 4 threads.

Dan The only info I have on this position is:

It is move 21
I entered this position in my test position database in 3/15/2003.
I cannot find the position in my game database.

I wish I had more info on all of my test positions.

My database shows three games that reached this position:

M Novik vs R Irzhanov at St Petersburg Open Feb 1994 (Drawn)
D Doric vs M Zufic in an event titled "TCh - CRO" 09 Sep 2004 (1-0)
G Crawley vs Say Hassan in an event titled "3rd Open" 04 May 2000 (0-1)

In all three games, White played Ne6 (not considered as strong as h3 by many different engines).

The database I found these in was Ed Shroder's Million Plus Updated list of 1.75 Million games.
