Re: Engine Test......Alekhine Move
Arasan finds this difficult (not solved in 5min, although on a slow machine).
If I may ask, what Alekhine game is this from?

Re: Engine Test......Alekhine Move....thanks
In my opinion Robert, a very good test move plus the fact that is being played by noless than Alekhine gives it an extra value to my eyes!! Here are the results from several programs on my pentium 3.2gzh:rightrook wrote:Thanks...! This must be a very good test move....Not very many replies or results posted...
My Junior 10 takes about 5 minutes to find Ng4....
regards
Robert

Re: Engine Test......Alekhine Move
Hi,
glaurung2.01 took a long think. To find out that Ng4 is better than Qg4 and to get a score of +203 it took 2044 sec.
Here some output on an AMD X2 5200+ running with 512 MB hash on 2 procs.
kind regards
Bernhard
