Test Position

I had HIARCS play the Nf6+ continuation out at 15 min/move.
White is winning, but it takes a while.

Code: Select all

Hi Marc,

Here are the CM9_R1 settings (only for use in the CM GUI!). All are default except:

Material/Positional = -7
Selective Search = 12
Transposition Table = 128MB (this is what I use for analysis, you can go smaller for blitz games)

Own/Opp Control of Center = 116
Own/Opp Mobility = 143
Own/Opp King Safety = 166
Own/Opp Passed Pawns = 137
Own/Opp Pawn Weakness = 137

Own Queen = 10.0
Opp Queen = 9.9
Own/Opp Rook = 5.4
Own/Opp Bishop = 3.4
Own/Opp Knight = 3.3
Own/Opp Pawn = 1.1

The King has always been an excellent tactical engine and brilliant at mate-finding.

Enjoy!

Crafty likes Rf6 instantly and the score climbs each iteration. Looks completely fatal for black.
